2005 Toyota Avalon Parking Brake Shoe Parts Q&A

• Q: What is the procedure to service and repair the Parking Brake Shoe on 2005 Toyota Avalon?

  A: You should start parking brake repairs by uninstalling the wheel while avoiding flexible hose detachment then removing the two bolts from the LH rear disc brake caliper assembly unit. First release the parking brake but maintain it marked while you both measure the rear disc and axle hub. Then take out the rear disc; in case of stiff resistance use the shoe adjuster to make the wheel spin freely. A brake drum gauge should measure the inside diameter of the rear disc which must be below 171 mm (6.73 inch) or require replacement. Use pliers with needle-nose to remove two return tension springs No.1 as the first step toward taking out both parking brake shoe struts LH with strut compression spring. The release of the spring cup claw allows you to remove the parking brake shoe assembly LH No.2 and No.1 while disconnecting the parking brake cable assembly No.3 and taking out the return tension spring No.2 and adjusting screw set. Begin the repair by first removing the 2 hold down compression springs along with their respective 4 hold down spring cups and pair of hold down spring pins. A screwdriver will help extract both the C-washer and the shim and shoe lever from the parking brake shoe assembly LH No.2. The shoe lining must be at least 1.0mm (0.039inch) thick per ruler standards; in this case replace all parking brake shoes as a set to maintain proper performance. An inspection for proper brake shoe lining contact can be made by applying chalk to the brake disc before adjusting the lining through grinding as needed. High temperature grease is applied to the backing plate before installation of the shoe lever and Shim to the parking brake shoe assembly LH No.2 using a new C-washer and feeler gauge clearance measurement to validate less than 0.35 mm (0.0138 inch); note that the Shim must be replaced if necessary. Thread the adjusting screw set and connect it to return tension spring No.2 as well as the hold down parts before reconnecting parking brake cable assembly No.3. Proceed to install the parking brake shoe strut LH along with its compression spring before you begin adding the two return tension springs No.1. Ensure you start with the front side spring. The assembly must have proper part installation and all friction surfaces must be free from oil and grease residue. To achieve proper parking brake shoe clearance, temporarily install the hub nuts while removing the hole plug. Follow by rotating the adjuster until the disc locks and finally contract it until the disc rotates freely while returning 8 notches. Use the hole plug before installing the rear disc brake caliper assembly LH. Tighten it to 62 Nm (630 kgf-cm, 46 ft. lbs.). Set the rear wheel with 103 Nm (1,050 kgf-cm, 76 ft. lbs.). Then check and adjust the parking brake pedal travel.
