How To Replace Parking Brake Shoe

Parking Brake Shoe Replacement

Helpful Information
The emergency/parking brake or "E" brake is used to securely hold the vehicle when in a stopped position. The brake is also designed to stop the vehicle in case of the primary system fails. On many vehicles with four wheel disc brakes, the parking brake has been integrated within the brake rotor disc.
This system is similar to the traditional drum brake systems with the exception of awheel cylinder. Most parking brakes are self adjusting, if the parking brake pedal seems low, or the brake doesn’t hold the vehicle there could be a problem and inspection is required.
Best Practices
  • Lift vehicle to manufacturers recommended instructions and secure with jack stands.
  • Brake material can contain asbestos. Avoid using pressurized air or other devices that can cause brake dust to become airborne.
  • Do not use a hydraulic jack to hold the vehicle while performing work.
Tools and Supplies Needed
  • Wrench set
  • Socket set
  • Lug wrench
  • Hydraulic jack
  • Jack stands
  • Replacement parking brake shoes
  • Shop towels
  • Protective eyewear and gloves.
  • Hammer
