What Causes Rear Wheel Lock-up in Volkswagen Jetta?

[DePhoebe]

The specific reasons for rear wheel lock-up in Volkswagen Jetta are as follows: 1. Water ingress into the brake drum causing rear wheel lock-up: If the vehicle has been parked for too long, moisture was not promptly removed after driving in the rain, or the brake drum was not treated after water ingress during car washing, the brake drum may rust, eliminating the gap between the brake drum and the brake shoes, leading to wheel lock-up. Replacing the brake pads In cases where rust on the brake pads causes rear wheel lock-up, the owner should visit a repair shop to replace the brake pads, which will resolve the issue of rear wheel lock-up. 2. Hard emergency braking causing rear wheel lock-up: During emergency braking, if the brake pedal is pressed too hard, the brake shoes may lock the wheels, meaning the brake locks the tires, and if the rear axle locks, it may cause rear wheel skidding. Installing an ABS anti-lock braking system Installing ABS can solve the problem of wheel lock-up during braking. The ABS system ensures that the wheels maintain a slight slip rolling state during braking without locking up, thereby improving braking efficiency.
