RICHMOND. Va, (Sept. 5, 2002) — General Motors Corp. has elevated Brake Align Runout Correction Plates to an “essential tool” for its dealers, according to Brake Align LLC, manufacturer of the products, used to eliminate brake pedal pulsation and related problems such as variations in brake rotor thickness.
Brake Align Runout Correction Plates have been on the market for more than two years and first received General Motors' approval in February of 2001. Since then, product acceptance by GM dealers has been “extremely strong,” particularly at the technician level, the company said.
With at least 18 months of data to support its decision, GM has granted the product “essential tool” status, meaning its use is mandatory for all GM dealerships attempting to remedy such problems. Brake Align said use of its product is the only warranty-approved method for correcting brake pulsations on GM's “N” platform cars, such as the 1997-2002 Chevrolet Malibu, '97-'99 Olds Cutlass, and “99-'02 Olds Alero and Pontiac Grand Am.
“General Motors feels they have found a significant warranty savings with the mandated implementation of Brake Align,' the manufacturer said in a news release. Brake Align also is in use at Midas, Meineke, Firestone and Goodyear service locations, the company said.
A GM service bulletin (No. 00-05-23-002A) that accompanied the Brake Align product release, explained that motorists may experience pulsation in the brake pedal or steering wheel during application of the brakes. The bulletin said further that in some cases, such pulsation has recurred within 3,000 to 7,000 miles of having had the vehicle's brakes serviced, tires rotated or any other type of service that requires wheel removal.
“Pulsation is the result of brake rotor thickness variation, causing the brake caliper piston to move in and out of the brake caliper housing,” the GM bulletin said. “…The major contributor to rotor thickness variation is excessive lateral runout of the rotor, causing the brake pads to wear the rotor over time.”
