What are the parking brake faults of Audi A6L?
1 Answers
Common parking brake faults include poor parking brake performance and the parking brake lever failing to stay in position. Poor parking brake performance: Symptoms: The vehicle can still start after pulling the parking brake lever, or it cannot stably stop on a slope, leading to slipping. The main causes of poor parking brake performance are excessive brake clearance, insufficient contact area between the brake shoes and drum, oil contamination or hardening of the brake shoes or lining, exposed rivets, or severe deformation of the brake drum or disc. Parking brake lever failing to stay in position: Symptoms: The lever cannot be released after pulling the parking brake lever, and it returns to its initial position when released. The main causes are a failed or broken pawl spring, which should be replaced; excessive wear or stripping of the pawl and gear teeth, which should be replaced; deformation or jamming of the pawl or lever, which should be corrected or replaced; or loose rivets on the pawl or gear plate, which should be repaired.
