How To Fix The Rear Wheel Locked Up While Driving?

Whenever you go car shopping, you usually heard about the rear wheel. The rear wheel is the wheel that receives the power from the engine and locates at the backside of the motor vehicle.

Friction is used by brake pads to slow the rotation of the rotor thus slowing the wheel and tire speed and ultimately slowing the car. If enough friction is applied to the rotor to stop its rotation or slow it to the point where the tire loses its traction and slide across the racing surface, This situation arises when the rear wheel locked up while driving.

Why Does Rear Wheel Lock Up?

The rear wheel locked up the problem is widely categorized into two parts. Firstly, due to mechanical problems and secondly due to Hydraulic problems in the system. Follow the symptoms and know the reason why the rear wheel locked up while driving.

6. Brake Shoe Contamination

Brake shoe contamination can be one of the reasons for the rear wheel locking wheel because it changes the coefficient of friction. If there is little contamination, the friction is increased. I there am severe contamination, the friction is reduced.
