2002 Toyota Land Cruiser Parts Questions & Experts Answers

• Q: How to service and repair the parking brake shoe on 2002 Toyota Land Cruiser?

  A: The first step for parking brake shoe maintenance requires initial removal of the wheel at 103 Nm torque and subsequent removal of the rear disc brake assembly by removing its 2 mounting bolts at 103 Nm torque. Securely suspend the assembly without stretching the hose. First create match marks on the disc and rear hub before taking off the component. Wheel rotation should be effortless if the disc shows signs of being difficult to detach. To proceed use needle-nose pliers to take out the tension spring from the backing plate alongside the rear shoe followed by the lower side tension spring. For removal of the 2 shoe return springs Special Service Tool: 09717-20010 should be used along with Special Service Tool: 09718-20010 to install the shoes on both the front and rear of the assembly. Start by taking off the shoe strut accompanied by its spring and then slide out the rear shoe including its adjuster while removing the shoe hold-down spring and 2 cups and pin until you reach the front shoe attached to the parking brake cable No. 2 from the lever with its respective shoe hold-down spring along with 2 cups and pin. The parking brake bellcrank assembly requires disassembly by removing the C-washer, pin, clip followed by 2 tension springs and then two bolts torqued at 13 Nm (130 kgf-cm, 9 ft. lbs.). To begin the inspection process, all components must be checked for signs of damage, rust and wear. Measurement of brake shoe lining material thickness should be taken at two points: 4.0 mm standard with a minimum acceptable value of 1.0 mm. Replacement of worn parts needs to occur if these measurements indicate so. Check and either replace or grind the brake disc when its inside diameter measures between 230-231 mm since uneven wear or scoring patterns are present. You should check the parking brake lining-disc contact point during this process while making adjustments when necessary before measuring the shoe-to-lever clearance (standard for less than 0.25 mm). Replace the shim if it is out of specification. The reassembly process occurs in the opposite order of disassembly by using high-temperature grease and lithium soap base glycol grease on designated parts. The parking brake shoe clearance adjustment requires cable disconnect followed by bellcrank tension spring removal followed by adjusting bolt loosening to temporarily install hub nuts, hole plug removal, shoe expansion until disc locking occurs and finally returning the adjuster 8 notches before reinserting the hole plug. The bellcrank adjustments begin with pulling it to remove play while screwing the adjusting bolt until it matches the dust seal position followed by loosening the bolt once and securing the lock nut to 5.4 Nm (55 kgf-cm, 48 inch lbs.). Afterward, reinstall the bellcrank tension springs followed by connecting the parking brake cable. The final step involves operating the vehicle at a 50-km/h (31-mph) speed while applying 88-N-force (9-kgf, 19.8-lbs.) to the lever across two or three consecutive 400-meter trips (0.25-mile) for checking and readjusting parking brake lever operation.
