2004 Toyota Sequoia Parts Questions & Experts Answers

• Q: How to service and repair the parking brake shoe on 2004 Toyota Sequoia?

  A: Service and repair of the parking brake shoe starts by taking out the rear wheel at 110 Nm (1,150 kgf-cm, 82 ft. lbs. torque). Starting with the rear disc brake assembly remove the two securing bolts with 105 Nm torque (1,070 kgf-cm or 77 ft.lb force) before hanging the assembly to protect the hose from stretching. After releasing the parking brake lever the technician should mark both the disc and rear axle hub and afterward remove the disc but can adjust the shoe when necessary to enable wheel rotation until free. To remove the 2 shoe return springs users must employ needle-nose pliers before taking out the shoe strut with spring which requires proper spring orientation forward when reassembling. The front shoe adjuster becomes accessible when sliding it outward while using needle-nose pliers to disconnect tension springs from the front shoe anchor before pulling off the front shoe with a clip remover protecting the cup. The process needs repetition for the back shoe where a clip remover should maintain pressure on the cup before reconnecting the parking brake cable to its shoe lever. All parts under inspection should be checked for wear and corrosion and rust damage and measurements should be taken for brake shoe lining thickness (standard 4.0 mm minimum 1.0 mm) before replacing the brake shoe when needed. Inspect the inside disc diameter using designated measurement tools (standard: 210 mm, maximum: 211 mm). Replacements need to be made or refreshing of the disc surface must occur if it exhibits scoring or uneven wear. Tests should measure the parking brake shoe lining contact with disc surfaces by using chalk powder for refinement as required. The technician needs to measure parking brake shoe to lever clearance (standard: less than 0.25 mm). If the measurement does not meet specifications the technician should replace the shim. Reassembly proceeds with a reverse pattern to disassembly where specified parts receive high-temperature grease application. The parking brake shoe clearance requires adjustment by screwing on three hub nuts and stretching the shoes until the brake disc locks before adjusting the 8 notches of the adjuster. Drive the vehicle at 50 km/h (31 mph) speed until you reach 400 meters (0.25 mile) while depressing the parking brake pedal with 147 N (15 kgf, 33 lbs) force for brake shoe and disc settling before performing the procedure an additional 2 or 3 times and inspecting parking brake pedal distance.
