One of the most important properties required for sports driving is “Braking Performance.” Brake tuning is as critical as suspension and engine tuning in providing a well balanced platform for high performance street or track use. With deep roots in motorsports, Mugen has designed the “Advanced Complete Brake System” to deliver maximum stopping power and reliability under all circumstances.
Rotor Design: The material is a proprietary Hi-Carbon Steel, the same
material Mugen uses for the brakes on their GT Race Cars. The "Reverse Bench Design" is
again, designed just for this application; fig. A illustrates how this
design draws air from the hub, and forces it out between the rotor
faces. With more, and larger vanes, the Mugen rotors move substantially
more air, and as the illustration shows, they draw it from a large
opening in the front, instead of a small opening in the back. The hats
have cooling holes, which also reduce unsprung weight. The braking
surface grooves are offset, front to back to eliminate brake judder. The
rotors are also thicker and have a bigger circumference to give
stronger braking and handle excessive heat. The rotors are 3/8” larger
than OEM and there are 18 additional cooling fins.
Caliper Design: This is a from-scratch design of a true monoblock. If
you have a rigid caliper, but it uses an adapter bracket, you’re going
to have flex and deformation at the braking surface, without exception.
These calipers mount directly to the factory points –completely
eliminating this deformation. Again, this isn’t a one size fits all
product with an adapter bracket for each application, it’s an
application specific design. To eliminate brake pad tapering and ensure
even pressure across the entire pad surface, Mugen produced these
calipers with different size leading and trailing pistons. Even the dust
boots are proprietary material, made to withstand prolonged excessive
heat.
The brake pad material is designed to change the braking force in the
rear to match the increased braking power of the front. Even the
material, routing and sleeves on the brake lines are made to minimize
heat damage to the brake fluid. Also, Mugen developed anti-squeal shims
specifically for this setup – the stock shims are not re-used.
This system is certainly streetable, but will withstand the most
demanding of track useage. Not simply a “brake upgrade”, or a “street
version” of a real racing system, these brakes are made to be on the
track where rotors routinely glow red for most of the race, and hold up
without fail.
Without question, this is a premium product, but this brake system is not for
everyone, it’s geared towards enthusiasts that drive hard on the street,
and drive even harder on the track.
