What does a parking brake malfunction in the Volkswagen Passat mean?
1 Answers
A parking brake system malfunction requires checking the working travel of the parking brake lever. If normal, the fault is generally caused by oil contamination or burning of the rear brake friction pads; if abnormal, the fault is usually due to excessive adjustment of the parking brake working travel, looseness in the parking brake cable connection, or poor movement due to obstruction. The main reasons for poor parking brake performance include: 1. Excessive clearance: Excessive brake clearance, too small contact area between the shoe and drum, oil contamination or hardening of the brake shoe or pad, exposed rivets, severe deformation of the brake drum or disc. 2. Looseness: Wear and looseness of the operating mechanism components, excessive clearance, or overly long cables.
