ATE PowerDisc with the multipurpose groove

The new ATE PowerDisc from ITT Automotive, one of the largest independent automotive componen suppliers in the world, is a world first in the field of brake discs. It has been intensively tested in races throughout Germany. Compared with conventional brake discs, not only does it bring significant safety benefits, it also offers better comfort and more even wear - in all vehicle classes with and without ABS.

Increased safety in wet conditions

The ATE PowerDisc's continous groove safely absorbs moisture which might settle between brake disc and pad and drains it off, like the tread of a tyre. Braking actions start sooner and brake-travel is shortened, as numerous instances of use in motorsport, test-drives and bench-tests have demonstrated.

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 been 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.

Braking in comfort

Unevenly worn brake discs tend to rub during braking. It is precisely in the particularly vibration-sensitive range from 90 to 130 km/h that the ATE PowerDisc's advantages over conventional brake discs come fully into play, with clear improvement in braking comfort.

To victory with ATE PowerDisc

In 1996, Sabine Reck made racing history on the Nürburgring when, driving a "PowerBlitz" BMW M 3 as one of the Scheid/Widmann/Reck team, she became the first woman to win a 24-hour race. "The ATE PowerDisc responds faster, so that I needn't brake so early when approaching bends. What's more, on the Nürburgring, which probably makes greater demands on the equipment than any other racing circuit in the world, great stability in the brakes is all-important."

With ABE, of course

Every ATE PowerDisc is officially Certified for General Use (ABE). That means no presentation to the Vehicle Inspectorate, no entry in the vehicle documents - simply install and brake more safely.

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!

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.
