Mini Cooper Big Brake Kit BBK Application Guide


      

The Mini Cooper Front Big Brake Kit (or BBK)  is the ultimate solution for improving braking performance.  The Big Brake Kit upgrade will:

  • Reduce stopping distances
  • Virtually eliminate Brake Fade under extreme conditions
  • Improve Pedal Feel for more accurate modulation
We strongly recommend the use of high performance brake fluid for maximum effectiveness.

Since the front brakes on the Mini performs a great majority of the stopping, a big brake kit on the rear is not necessary.  Simply upgrading the rear brake pads to match your application is sufficient to maintain the brake balance.

The primary reason for installing a Big Brake Kit is for improved braking performance under extreme conditions such as track day events.  The BBK allows drivers to go deeper into turns before braking.  Stock brakes will lose effectiveness as they heat up and eventually begin to fade.  The BBK will allow consistent braking performance throughout track day events and pretty much eliminate brake fade.  It would be extremely rare to 'overcook' the BBK. 

Other owners install the BBK for the 'looks' with the huge calipers and drilled and/or slotted rotors peeking thru their rims. 

These Big Brake Kits typically include 'street performance' type pads.  These pads are fine for an occasional track day, however if you frequent the track, it is recommended that you get a set of 'track pads' for track duty.

IMPORTANT NOTE:

Most of these Big Brake Kits have oversized calipers requiring a lot of space behind the wheels.  Most of these kits will NOT fit under stock wheels - GO TO THE PRODUCT PAGE AND USE THE LINKS TO BRAKE CLEARANCE TEMPLATES TO CHECK YOUR WHEELS BEFORE YOU ORDER THE BIG BRAKE KITS.   Some kits may fit with the addition of spacers, and other kits require different wheels altogether.

The OEM JCW kit and the Wilwood Kits have the smallest calipers.

While the JCW kit uses an oversized 4-piston caliper with larger rotors, the rotor is still a single piece unit.  The aftermarket BBK's all use larger 2-piece full floating rotors with alloy hats which reduces weight and improves heat dissipation.

The alternative to the Big Brake Kit is to upgrade the Rotors, Pads, and brake fluid.  Although the Big Brake Kits will always perform better than the rotor and pad upgrade, it is more expensive.  If you are on a tight budget, take a look at the following:
