Chevrolet Uplander: Brakes
Affects Chevrolet Uplander · 2005 — about 4K vehicles.
The hazard
Certain vehicles do not comply with the requirements of CMVSS 135. To meet the Standard, the vehicle must not move for five minutes when stopped on a steep hill with the parking brake applied and the vehicle in NEUTRAL (N). A part that was not manufactured to specifications can cause the parking brake to fail this test. A loud popping noise as the parking brake is applied or a sudden decrease in the effort required to apply the parking brake can be indications of this condition. When the parking brake is released, the driver may notice unintended braking when accelerating, decelerating, or coasting, and a groan, humming, and/or vibration coming from the rear of the vehicle. Correction: Dealers will inspect for parking brake lever slippage at each rear brake caliper. The calipers will be replaced if lever slippage is identified.
