What are the causes of the parking brake failure in the Touareg?
1 Answers
The main causes of the failure are excessive clearance between the friction pads and the brake drum, oil contamination on the friction pads and brake drum, severe wear of the friction pads, exposed rivets, or surface hardening leading to slippage. It may also be due to severe wear of the parking brake pins, excessive clearance, or over-adjustment of the parking brake lever. Types of parking brakes: 1. Traditional handbrake: The traditional handbrake is a mechanical mechanism operated by hand or foot. When starting, the driver needs to manually release the handbrake or skillfully coordinate the throttle and clutch for a smooth start. 2. Electronic parking brake: This is a technology that achieves parking braking through electronic control. Its working principle is the same as that of the mechanical handbrake, both relying on the friction generated between the brake disc and brake pads to control parking braking, except that the control method has changed from the previous mechanical handbrake lever to an electronic button.
