Endless

Choose Endless brake pads for rally and circuit racing, in a range of competition compounds including ME20, N35S, N39S and N105SP. Each pad is listed with its dimensions and cross references to AP Racing, CL, Ferodo, Mintex, Pagid and PFC pad shapes, so you can find the right fit for your caliper. The range also includes Endless RF-650 racing brake fluid, with a 328°C dry boiling point.

Endless Brake Pads

Endless racing compounds are developed for the extreme conditions of competition braking, with stable performance across a wide temperature range and low pad and disc wear. Here’s what to look for:

  • Racing caliper pad shapes, such as RCP002, RCP108 and RCP173, each listed with full dimensions
  • Cross-reference filters for AP Racing, CL, Ferodo, Mintex, Pagid and PFC pad shapes, plus AP Racing caliper numbers, so you can search by what you already run
  • Vehicle filters covering rally and race cars, from modified MK2 escorts through to Rally4, Rally3 and Rally2 
  • Endless RF-650 brake fluid, built to hold its boiling point under severe braking

Choosing the Right Endless Compound

Endless make a wide range of competition compounds. These are four of the most common:

Compound

Friction (µ)

Heat range

Best for

ME20

0.35 to 0.40

150 to 800°C

Racing and rally, originally developed for BTCC Super Touring cars. Easy modulation, low pad and disc wear, and resists water fade in cold and wet conditions

N35S

0.42 to 0.52

300 to 800°C

Quick initial bite with low pedal pressure and low lock-up tendency. Balanced in wet and dry, making it popular for tarmac and gravel rallying

N39S

0.42 to 0.52

0 to 850°C

Shares N35S’s properties with a step higher initial bite and quicker response. Builds friction well from cold, with excellent temperature resistance and low pad wear 

N105SP

0.52 to 0.75

300 to 800°C

The highest initial bite in Endless’ SP series, with high heat resistance. Works directly from cold, gentle on discs, low pad wear, and proven in tarmac rallying and circuit racing

Finding the Right Pad Shape

Endless racing pad part numbers follow a simple format: RCP stands for Racing Caliper Pad shape, followed by the shape number, the compound and the thickness. For example, RCP002ME20-16 is the RCP002 pad shape in ME20 compound, 16mm thickness.

If you know the pad you currently run, use the cross-reference filters to search by your existing AP Racing, CL, Ferodo, Mintex, Pagid or PFC pad shape, or by your AP Racing caliper. Each product page also lists pad width, height, radial depth and thickness, so you can check the dimensions against your current pads before ordering. If there isn’t an Endless pad in the shape you need, our full range of competition brake pads covers other brands or contact our sales team for more information.

Frequently Asked Questions

Which Endless compound should I choose?

ME20 is the most forgiving, with easy modulation and low wear. N35S steps up to a quicker initial bite and is a popular choice for tarmac and gravel rallying. N39S builds on N35S with a higher initial bite and better response from cold. N105SP has the highest initial bite in Endless’ SP series and works straight from cold.

How do I bed in Endless brake pads?

Start by checking your discs for damage and cleaning off any old pad residue. Any cracked or damaged discs should be replaced with new brake discs before you start, since defects will affect both the bedding process and the pads’ performance. Then make about 10 smooth but hard stops from around 100 km/h to a standstill, aiming for a disc temperature of around 350°C, and let the brakes cool completely. On track, three laps at 80% pace with normal race braking does the same job. The brakes can feel poor during bedding, which is normal. See the full Endless bedding-in instructions for details.

What temperature do Endless brake pads work best at?

The Endless bedding-in instructions recommend 300 to 700°C as the best operating range for their competition pads, though they still perform well outside it. Each compound has its own heat range, listed in the table above and on the product page, with most topping out around 800°C and N39S rated up to 850°C. If your brakes regularly run above 650°C, the car needs more brake cooling rather than a different pad.

Can I fit Endless pads if I currently run another brand?

Yes, as long as the pad shape matches your caliper. Use the cross-reference filters to search by your current AP Racing, CL, Ferodo, Mintex, Pagid or PFC pad shape, then check the dimensions on the product page against your existing pads.
