Remote release handle Parking brake control Parking brake rear cable and conduit clip (part of 2A635) Parking brake cable bracket Parking brake rear cable and conduit— (LH) Parking brake rear cable and conduit— (RH) Parking brake cable equalizer Front parking brake cable and conduit Front parking brake cable clip The parking brake system is actuated when the parking brake control (2780) is depressed. The parking brake control applies tension to the front parking brake cable and conduit (2853) and parking brake cable equalizer (2A602). The parking brake cable equalizer is coupled to the RH parking brake rear cable and conduit (2A635) and the LH parking brake rear cable and conduit. The respective rear brake assemblies are then applied. The rear wheel brake assembly contains a cable-actuated parking brake assembly. The parking brake releases the rear brakes using a remote release lever incorporated with the parking brake control. If the parking brake control is not fully released, the parking brake signal switch will illuminate the brake warning light. The parking brake signal switch is mounted on the parking brake control. The switch is held in place by a self-tapping screw and aligned with a locater pin. The drum brake parking brake system is self-adjusting, therefore cable tension does not need to be adjusted.

Introduction Some 2010 Prius vehicles may experience rear brake squeak when backing up or moving forward during the ?rst few brake applications when the brakes are cold. An updated rear brake shim kit is available to reduce the likelihood of this condition occurring. Repair Procedure 1. Test drive the vehicle to con?rm the squeak is coming from the rear brakes. The condition occurs more frequently when backing up during light brake pedal application after cold soak. 2. Remove rear brake shims. Refer to the Technical Information System (TIS) 2010 Prius Repair Manual: Brake – Brake (Rear) Brake: Rear Brake: Removal 3. Clean the rear brake pad backing plates with a clean shop towel and apply a small amount of black disc brake grease to the backing plate of each rear brake pad. NOTE Make sure disc brake grease is not applied to the lining of the rear brake pads. 4. Install the No. 1 Anti-squeal shims. Install the No. 2 Anti-squeal shims. Figure 3. 5. Using the Variable Pin Wrench (SST 09960-10010), slowly rotate the caliper piston until the piston groove is positioned as shown in the illustration below. 6. Install new rear brake anti-squeal shims with brake pads into the rear caliper assemblies brackets. Refer to (TIS), 2010 Prius Repair Manual: Brake – Brake (Rear) Brake: Rear Brake: Installation NOTE • When installing the rear disc brake caliper assembly on the rear disc brake caliper mounting bracket, ensure the protrusion on the brake pad is centered in the caliper piston groove. • It is important to ensure the protrusion is not contacting the outer edges of the caliper piston groove. (both sides) 7. Road test the vehicle to con?rm the condition has been reduced.

1. NOTE: Make sure the parking brake control is fully released. Relieve the tension on the parking brake system. 1. Pull the front parking brake cable and conduit. 2. Insert a suitable retainer. 2. CAUTION: Do not use heat to loosen a seized lug nut (1012). Heat can damage the wheel and the wheel bearings. Remove the rear wheels and tires; loosen the lug nuts. 1. Remove the center cap. 2. With the weight of the vehicle on the wheels, loosen, but do not remove, the lug nuts. 3. WARNING: THE ELECTRICAL POWER TO THE AIR SUSPENSION SYSTEM MUST BE SHUT OFF PRIOR TO HOISTING, JACKING OR TOWING AN AIR SUSPENSION VEHICLE. THIS CAN BE ACCOMPLISHED BY TURNING OFF THE AIR SUSPENSION SWITCH LOCATED IN REAR JACK STORAGE AREA. FAILURE TO DO SO MAY RESULT IN UNEXPECTED INFLATION OR DEFLATION OF THE AIR SPRINGS WHICH MAY RESULT IN SHIFTING OF THE VEHICLE DURING THESE OPERATIONS. Raise and support the vehicle; refer to Section 100-02 . 4. Remove the tire and wheel assembly. 1. Remove the lug nuts. 2. Remove the tire and wheel assembly. 5. Disconnect the (A) parking brake intermediate cable from the (B) parking brake rear cable and conduit, LH. 6. Separate the (A) RH parking brake rear cable and conduit from the (B) LH parking brake rear cable and conduit at the (C) parking brake cable equalizer. 7. Remove the RH parking brake rear cable and conduit from the parking brake cable bracket (2530). 1. Compress the parking brake cable clip. 2. Remove the RH parking brake rear cable and conduit from the parking brake cable bracket. 8. Remove the RH parking brake rear cable and conduit to LH parking brake rear cable and conduit clip. 9. Remove the (A) RH parking brake rear cable and conduit from the (B) rear parking brake cable retainer (2A709). 10. Remove the RH parking brake rear cable and conduit to the RH hydraulic brake line clip. 11. Remove the parking brake cable retainer clip (2A826). 1. Remove the parking brake cable retainer clip bolt. 2. Remove the parking brake cable retainer clip. 12. Unclip the parking brake rear cable and conduit from the brake line clip on top of the rear axle housing.

WARNING: Occupational health and safety act (OSHA) requires areas where asbestos dust generation is possible to be isolated and posted with warning signs. Only technicians performing brake or clutch repair are to be present in the area. 1. Remove the rear disc brake rotor. For additional information, refer to Section 206-04. 2. Disconnect the rear parking brake cable at the parking brake intermediate cable (2A793). 3. Disconnect the parking brake cable at the parking brake lever. 4. Remove the outboard brake shoe retracting spring. 5. Remove the brake shoe adjusting screw spring. 6. Remove the brake shoe hold-down springs. 7. Remove the brake adjuster screw (2041). 8. Remove the parking brake shoe and linings (2N712) along with the inboard brake shoe retracting spring. 9. Inspect the components for excessive wear or damage and install new as required. Installation 1. NOTE: Make sure the inboard brake shoe retracting spring is attached to the parking brake shoe. Install the LH parking brake shoe and brake shoe hold-down spring, along with the inboard brake shoe retracting spring. 2. Connect the inboard brake shoe retracting spring to the RH parking brake shoe, and install the RH parking brake shoe and the brake shoe hold-down spring.

CAUTION: Refer to Brake Dust Caution in Cautions and Notices. 1. Inspect the fluid level in the brake master cylinder reservoir. 2. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, then no brake fluid needs to be removed from the reservoir before proceeding. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, then remove brake fluid to the midway point before proceeding. 3. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information. 4. Remove the rear tire and the wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels. 5. Install a hand tightened lug nut to retain the rotor to the hub. 6. Compress the caliper piston enough for clearance. Use a C-clamp (3). NOTE: NOTE: Use care to avoid damaging pin boot when rotating caliper. Support the brake caliper with heavy mechanic’s wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
