MINI (2002-Current)
Replacement Front Polymatrix B brake pads for the Wilwood Big Brake System NMB2041.

Fits all current MINI models (except Countryman).


  • Medium-high friction, good cold response
  • Gently rising torque curve, predictable engagemnet
  • Low wear rate at medium temperatures, increasing to moderate at high temperature.
  • Medium-high friction, good cold response

* Medium-high friction compound with good cold response and a gently rising friction curve as temperature increases.
* Smooth, predictable engagement with excellent control over a wide range of applications.
* Long wearing pad in the middle temperature ranges with moderate wear in sustained high heat conditions.
* Easily bedded without abrasion on new iron or steel rotors.

Race ONLY compound used in ARCA, ASA, ALMS, Grand-AM, NASCAR, REMAX, SCCA, USAC, and other severe duty oval, road course, and off-road series that require an aggressive response and durability in the highest temperature ranges.

Lightweight sprints and club sport racers using steel plate rotors that require fast response at low temperatures with resistance to fade during periodic or temporary high temperature spikes.

Temperature range and overall friction value are the primary considerations for pad selection. The pads must be capable of maintaining the proper amount of friction for stopping power within the temperatures that will be realized on the track during the event. Then, overall wear rate must be considered. For most asphalt and road race applications, compounds in the high temperature ranges over 1000°F range are usually necessary. Dirt track, drag race, and street performance applications usually operate at temperatures between 500° and 1000°F. Keep in mind that these are general ranges, and not absolute values. Many factors and unforeseen influences can affect brake temperatures. The best indicator for pad selection will always be on track performance. If pad fade (friction loss) due to overheating occurs, then improved cooling, a heavier rotor, or a higher temperature range pad may all become necessary.

For other pad types, see NMB2045-P.

Brake fluid should be replaced every 2 years, more often if you track your MINI.
