• Q: How to overhaul the parking brake shoe on 2001 Toyota Highlander?

  A: You should start the parking brake shoe overhaul by taking off the wheel along with the rear disc brake caliper assembly LH yet leaving the flexible hose intact. First free the parking brake then take off the rear disc [42431/98-63] while noting the disc and axle hub positions; wheel rotation should be possible before disc removal when shoe adjustment cannot achieve this. You must use a brake drum gauge to measure the inside diameter of the brake disc. The standard size is 170 mm (6.69 inch) yet the maximum allowed measurement is 171 mm (6.73 inch). Comply the following sequence to remove the brake components: First, detach the parking brake shoe return tension spring [46550G/98-78] using needle-nose pliers followed by extracting the parking brake shoe strut compression spring [47613D/98-78] by sliding out the front shoe. Begin by removing the parking brake shoe strut LH [47614/98-78] followed by the parking brake shoe through cup claw release and parking brake cable disconnection from the shoe lever then removal of tension spring and shoe adjuster screw set and two shoe hold-down springs and four cups and two pins. To remove the C-washer along with the shim and shoe lever from the parking brake shoe insert a screwdriver. The recommended measurement of parking brake shoe lining thickness is 2.0 mm (0.079 inch) while the minimum accepted value is 1.0 mm (0.039 inch). If any brake shoe lining drops below minimum thickness or indicates uneven severe wear, the affected brake shoe requires replacement. Observe shoe lining contact with brake disc by applying chalk on the inner disc surface before grinding the lining as needed. The shoe attached surface of the backing plate requires high-temperature grease before shoe installation while attaching the shoe lever along with shim to the rear shoe using a new C-washer. The required tool is a feeler gauge for clearance measurement which must be below 0.35 mm (0.0138 inch) standard. Replace the shim when the measurement does not meet specifications. First grease the adjusting bolt before setting the shoe adjusting screw set together with the tension spring and securing the two pins as well as four cups and two shoe hold-down springs. The parking brake cable must be joined to the shoe lever before installing the front and rear parking brake shoes. Reinstall needle-nose pliers to secure the parking brake shoe strut LH [47614/98-78] as well as the parking brake shoe strut compression spring [47613D/98-78] and the parking brake shoe return tension spring [46550G/98-78]. The installation must include a double-check to confirm every element is in its correct position with no evidence of oil or grease residue on the friction surfaces. First install only the hub nuts then remove the hole plug to adjust the parking brake shoe clearance by rotating the adjuster until the disc locks and then turn the adjuster back until the disc rotates freely while returning the adjuster 8 notches. The final procedure involves checking brake performance with the hole plug in and the rear caliper assembly attached with 47 Nm (480 kgf-cm, 35 ft. lbs.) torque using two bolts. Then secure the rear wheel with 103 Nm (1,050 kgf-cm, 76 ft. lbs.). To complete the process adjust the parking brake pedal according to specifications.
