2003 Toyota 4Runner Parking Brake Shoe Parts Q&A

• Q: What is the procedure to overhaul the Parking Brake Shoe with a 210 mm brake disc on 2003 Toyota 4Runner?

  A: Start the parking brake overhaul process by taking off the rear wheel followed by disconnecting the rear disc brake caliper assembly LH through unbolting its 2 mounting points that do not affect the flexible hose. After releasing the parking brake to remove the rear disc you must mark its brake disc and axle shaft location and readjust the shoe till the wheel spins freely. Use a brake drum gauge to check the brake disc inside diameter for compliance with the specification of 210 mm and maximum 211 mm. Sliding out the front shoe requires using needle-nose pliers to remove the 2 return tension springs until the compression spring can be extracted. The parking brake shoe strut LH and brake shoe require removal after disassembling the cup claw followed by disconnecting the parking brake cable from the shoe lever and removing the tension spring in combination with shoe adjuster screw set and 2 shoe hold-down springs along with 4 cups and 2 pins. To remove the C-washer operate a screwdriver before removing the shim and shoe lever from the parking brake shoe. Use a ruler to check shoe lining thickness because it should rest between 4.0 mm and 1.0 mm specifications. Perform replacement if necessary. Deaden the brake disc by applying chalk before adjusting the shoe lining contact with the brake disc through grinding as needed. High-temperature grease should be used to coat the shoe attached surface of the backing plate before you place the parking brake shoe along with its shoe lever and shim which will require a new C-washer. A feeler gauge measurement must show clearance below 0.25 mm for the correct shim replacement if the specification is not met. After applying grease to the adjusting bolt and piece the technician installs the shoe adjusting screw set and tension spring and positions the 2 pins, 4 cups, and 2 shoe hold-down springs. Next they must connect the parking brake cable to the shoe lever before mounting the front and rear parking brake shoe. Install the parking brake shoe strut LH and pair it with compression spring while adding return tension springs but line up the front side spring as the first step of assembly. Make certain that each component is correctly placed without any oil or grease contacting the friction surfaces. The shoes should be adjusted until the disc becomes locked then the adjuster is contracted 8 notches while the disc spins effortlessly. Check whether the brakes free correctly before you reinstall the hole plug. The rear disc brake caliper assembly LH requires installation with two bolts torquing to 105 Nm before installation of the rear wheel torquing to 112 Nm. The completion of the process requires an inspection and adjustment of parking brake pedal travel when needed.
