Inspection at a glance
Visual, electric and acoustic wear-indicators have long been available for brake pads. Until now the expert glance in the workshop has generally had to suffice for brake discs, since precise measurement was costly: special measuring equipment was necessary and the wheels had to be removed. Now the multipurpose groove makes objective assessment of the condition of the brake disc possible at a glance. If the entire groove has been. worn away, the disc has reached its minimum thickness and must be replaced.

Scoring-free wear
The multipurpose groove's cleaning action causes the brake disc to wear more evenly. Even in heavy-duty use hardly any scoring occurs on the brake disc or pads.

Reduced fading
In hard use, brake discs can reach temperatures of 800° C and more. The result: gas emissions develop on the brake pad, primarily because of the bonding material, which can lead to a "Gas-Planing Effect" (fading). A temporary decrease in the coefficient of friction is the result. The ATE PowerDisc channels off these gas emissions via the multipurpose groove and so prevents fading. That means there is no increase in the force required to depress the brake pedal a plus for safety!

Braking in comfort
Unevenly worn brake discs tend to rub during braking. It is precisely in the particularly vibrations sensitive range from 90 to 130 km/in that the ATE PowerDisc's advantages over conventional brake discs come fully into play, with clear improvement in braking comfort as shown by the above diagram of a heavy-load test.

High Performance Rating (HPR)
Mintex 1144 (Race/Rallye): This compound has a higher temperature and nominal friction coefficient (.45) rating than the 1207 and are typically used for extreme braking conditions.

Mintex 1155 (Race): Similar high performance range as the 1144 but with a .42 nominal friction coefficient rating. Note that the rear HPR pads only come in this compound.

First, it is important to inform the customer that metallic pads should not be installed on a vehicle with worn rotors. A soft, organic pad will conform to the grooves in a worn rotor while a metallic pad will not. It is therefore essential to either replace or turn rotors when installing Mintex brake pads.

After installing Mintex pads they should be bedded-in to insure top performance.
Accelerate to approximately 40 M.P.H. and apply the brakes with moderate pedal pressure.
Slow to approximately 5 M.P.H.
Repeat this procedure 10 times allowing 1/3 of a mile between stops.
Do NOT attempt to bed-in pads by driving the vehicle with the brakes constantly applied. This will damage pads and result in decreased performance.
