Custom wind turbine brake pads for yaw and rotor brakes
FTL is a custom wind turbine brake pad manufacturer, making new, existing and obsolete yaw and rotor brake pads for wind programmes in the UK and Europe.
Start with the application, an existing pad, a drawing or the performance problem, not simply a part number.
We develop the friction material and the complete pad around what the yaw or rotor brake must do, the conditions it runs in and the evidence required before repeat supply.
For the wider sector context, explore our wind energy materials and engineering.
When wind teams need a custom brake pad
The correct route depends on what has prompted the requirement.
A new turbine or brake programme needs a custom pad
The yaw or rotor braking function is understood, but the friction material, pad construction or repeatable production route has not yet been established. FTL can support the programme from application review and material selection through prototypes, testing, validation support and controlled repeat manufacture.
New Programme Support →An existing yaw or rotor brake pad is not performing as required
Inconsistent braking, excessive or unpredictable wear, thermal-performance concerns, or variation between manufactured pads or production batches. FTL can review the available evidence across the friction material, complete pad, operating environment and production route.
Performance Optimisation →An original pad, material or supplier is no longer available
The turbine must stay in service, but the original material, drawing, supplier or complete brake pad has become obsolete. FTL can review the existing pad and available evidence before proposing a redevelopment, prototype and revalidation route.
Legacy & Obsolete Reverse Engineering →The pad currently passes through too many suppliers
The friction material, backing plate, machining, bonding, finishing and inspection are divided between separate organisations. FTL can connect the relevant stages through one accountable manufacturing route.
Single-Source Friction Manufacturing →A prototype must progress into controlled repeat supply
The engineering solution needs to move into a defined production arrangement supported by repeat manufacturing controls, inspection, traceability, inventory holding, scheduled call-off, customer-specific packaging and identification, and delivery.
New Programme Support
For a new yaw or rotor brake requirement that needs a defined friction-material, pad-construction and manufacturing route. Support can include application review, material selection or formulation, pad and backing-plate engineering, prototype manufacture, testing and inspection, validation support and transfer into controlled repeat production.
Legacy & Obsolete Component Reverse Engineering
For a wind turbine pad still required after its original material, drawing, supplier or finished component becomes unavailable. Support can include existing-pad and evidence review, dimensional assessment, geometry redevelopment, alternative material selection or development, prototype manufacture, testing and revalidation support and repeat manufacture.
Friction System Performance Optimisation
For an existing yaw or rotor brake pad with inconsistent braking, excessive or unpredictable wear, thermal-performance concerns or production-repeatability problems. Support can include symptom and evidence review, operating-condition assessment, investigation of material and component factors, alternative formulation or component work, comparative prototypes, testing and inspection and implementation support.
Move from a brake-pad requirement to a controlled engineering and supply route
A custom wind turbine brake-pad project should define more than the pad's visible shape.
The engineering route must establish the required function, friction material, complete-pad construction, manufacturing stages, inspection evidence and responsibilities that apply before repeat supply begins.
Potential engineering outcomes
- A shared definition of the application and required braking or holding function
- A friction-material selection or development route
- A defined pad geometry and backing-plate route
- A prototype and test plan
- Agreed inspection and acceptance requirements
- Clear FTL and customer validation responsibilities
- A documented decision on whether further development is required
Potential manufacturing and supply outcomes
- One accountable route from friction material to finished pad
- Controlled machining, bonding, finishing and inspection
- Defined production records and traceability
- Progression from prototype into repeat manufacture
- Inventory and scheduled call-off where agreed
- Customer-specific packaging and labelling
- Scheduled delivery
Performance, service life, lead time and approval outcomes depend on the application, available information, agreed testing and respective customer and FTL responsibilities.
What a wind turbine brake-pad project can include
Not every project requires every stage. FTL can make the friction material, the finished pad or the complete brake component.
For FTL's composite yaw pads, backing plates are available in steel or in glass-fibre reinforced material, and the pads are made to a tight tolerance so they sit in the brake calliper without lateral movement. A complete project can draw on friction-material selection, pad and backing-plate engineering, machining, bonding, surface preparation, finishing, assembly, inspection and the move into controlled repeat supply.
Small batches, prototypes and repeat supply
FTL makes wind turbine brake pads in small batches as well as in repeat production.
A project can start with prototype pads, move to a low-volume batch and then into scheduled production, with finished pads held for call-off where agreed. FTL's minimum order depends on the part and the enquiry, and is confirmed for each component with the quantity range, set-up and commercial fit. For a pad that is no longer made, the reverse engineering route starts from the existing part.
What FTL needs to understand before recommending a brake-pad route
A material name, nominal coefficient or existing part number does not define the complete requirement.
Begin with the brake and what the pad must achieve.
What is the application?
- Yaw brake, or rotor or other disc brake
- What the brake is required to stop or hold
- Whether the turbine is new or already in service
- What has prompted the enquiry

Is this a new design or an existing brake pad?
- A new programme
- A new pad for an existing turbine
- An existing pad under performance review
- An obsolete pad
- A supply-continuity issue
- A prototype moving towards production
What conditions will the pad run in?
- Applied load or pressure
- Relative speed
- Temperature
- Contamination
- Braking or holding duration

Inputs that shape the material decision
- Required braking or holding behaviour
- Coefficient stability
- Wear rate
- Thermal performance
- Load, speed, temperature, contamination
- Pad and backing-plate geometry
- Bonding and finishing requirements
- Inspection and validation evidence
Published data is a starting point. Final material selection depends on the complete application and agreed validation route.

Testing and inspection tied to defined engineering questions
Testing should be selected around what the project needs to establish, not used as a general claim that a pad will perform in every wind turbine brake.
Depending on the agreed scope, a project can draw on coefficient-stability and wear-rate assessment, thermal-performance and bond-integrity testing, CMM dimensional inspection and production evidence such as in-process checks, final inspection and batch traceability. The available methods, conditions and acceptance evidence are described in full on the testing and inspection capability page.
The exact samples, test conditions, methods, acceptance criteria and customer responsibilities must be agreed before testing begins.
Keep the friction material connected to the finished brake pad
A fragmented route can divide responsibility between the material formulator, friction-component machinist, backing-plate supplier, bonder, finisher, test provider and inspector.
FTL can connect the relevant stages through one engineering and manufacturing chain, helping keep the material, component and production decisions aligned and the friction material connected to the finished pad.
The full connected route, from application review through friction-material selection, machining, bonding, finishing, testing and traceability to scheduled supply, is set out on the Single-Source Friction Manufacturing page.
Actual lead-time, procurement or cost benefits depend on the current supply arrangement and agreed project scope.
Wind turbine brake pads for yaw and rotor brakes
FTL's wind grades cover yaw brakes, rotor and other disc brakes, and wider turbine and generator braking.
Each enquiry still requires review of the individual turbine, brake and operating environment.
Yaw brakes
Composite yaw pad materials FTL-207, FTL201, FTL203 and FTL204, with FTL-207 formulated and optimised for wind turbine yaw systems, and the organic grade FTL087. Wear in a yaw brake depends on braking force, sliding speed and distance, how often the system moves and the mating surface, so the pad is chosen around the installation.
Rotor and other disc brakes
FTL135.2, a DNV-GL approved organic material, for disc brake pads on wind turbines, and the sintered grades FTL004 and FTL509 for wind energy brake pads, both made for dry running. FTL509 is joined to a steel back plate.
Wider turbine and generator braking
The sintered grades FTL510 and FTL513 for wind turbines and FTL511 for wind generators. FTL510 and FTL513 are free of asbestos, lead and zinc; FTL511 is oil resistant.
Oil, grease and chemical exposure
FTL201, FTL203 and FTL204 suit installations where oil contamination is likely, and resist chemicals and grease. FTL087 and FTL511 are also oil resistant.
These are application contexts rather than stock product categories. FTL should confirm technical fit for every enquiry.
Questions buyers need answered before approving a wind turbine brake pad
Can FTL match or improve the current material performance?
FTL can review the current pad, available material information, operating conditions and required behaviour before proposing an established, optimised or newly developed route. Whether performance can be matched or improved depends on available application evidence, defined operating conditions, complete pad construction, agreed test conditions, acceptance criteria and validation responsibilities. No outcome is promised before the review and required development work are complete.
Is the proposed pad already proven in service?
Where relevant application history or established-material evidence exists, FTL can identify it during the technical discussion. A new, modified or redeveloped wind application may still require project-specific testing and customer validation.
How does FTL support consistent quality and repeatability?
The available route connects friction-material formulation, pad and backing-plate engineering, machining, surface preparation, bonding, finishing, testing, inspection, production documentation and batch and lot traceability. The exact production controls and acceptance requirements are agreed for the individual project.
Can FTL manufacture the complete pad?
Yes, where the project fits FTL's confirmed scope. FTL can support the friction material and complete-pad route through engineering, machining, bonding, finishing, testing, inspection and repeat supply.
Can FTL supply the pads sooner?
There is no standard lead time for every wind turbine brake-pad project. Timing depends on information available, material-development work, pad and backing-plate complexity, prototype iterations, testing and inspection, customer validation, production quantities and supply requirements. FTL confirms the proposed stages and timing after the initial technical review.
Can the price be improved?
Pricing depends on the agreed engineering, material, component, testing, documentation, volume and supply scope. The first conversation establishes technical fit. Commercial options can then be reviewed against the actual requirement rather than a standard online price.
A trusted, accountable supplier since 2003
High-performance friction and braking solutions, backed by decades of in-house expertise and made in North Wales.
Company-level standards support organisational and manufacturing assurance. Material suitability, component acceptance and programme requirements must still be agreed for the individual wind application.
Brake-pad engineering backed by controlled manufacture
SDTS approached FTL after an original aircraft brake pad became unavailable. FTL redesigned the pad, established a replacement material route and manufactured a component aligned with the stated aeronautical technical requirements, supporting SDTS's modification-certification process. This is an aircraft brake-pad example that shows the manufacturing capability behind a redeveloped pad, rather than wind proof.
“To continue flying our aircraft, we approached FTL to find replacement solutions for our brake pad problem, as the original part was no longer available on the market. The quality of our discussions, from both a technical and commercial standpoint, FTL's responsiveness in redesigning the pad with a material that meets aeronautical technical requirements, and their ability to adapt to our aeronautical environment allowed us to certify a modification applicable to our aircraft. The quality of the manufactured product is remarkable. Thanks to FTL, we can continue to fly, land, and brake safely.”

Is FTL the right route for your wind turbine brake-pad requirement?
FTL is a strong fit when:
- Your team has an application brief rather than a stock-parts request
- A new yaw or rotor brake pad requires a custom material or component route
- An existing pad has braking, wear or thermal concerns
- The original material, drawing, supplier or complete pad is obsolete
- The requirement includes a bonded pad or backing plate
- Prototype work may need to progress into repeat manufacture
- Testing, inspection and traceability matter
- You want fewer suppliers across material, machining, bonding and finishing
- The finished pads require scheduled supply
A different route may be more appropriate when:
- You need an off-the-shelf pad immediately
- You are purchasing solely by part number
- You need a stock catalogue
- Price is the only selection criterion
- No technical or manufacturing review is required
