Removal 1. Open engine compartment hood and fit paint protection covers to fenders. Raise and support vehicle. Remove wheels. 2. Release the tension on the parking brake cable by moving the parking brake caliper lever away from the cable end. Remove cable from parking brake cable lever. See Fig. 32 . 3. Remove the parking brake cable from the rear brake caliper. On vehicles with manually adjusted parking brakes, remove the retaining clip. See Fig. 33 . On vehicles with self-adjusting parking brakes, release the tabs on the parking brake cable housing. See Fig. 38 . NOTE: To prevent the loss of brake fluid, apply the brake pedal hold down tool and adjust to hold the brake pedal down 1.6″ (40 mm). Install a bleeder bottle to the bleed nipple and loosen the bleed nipple. 4. Remove union bolt from the rear brake caliper hose and discard sealing washers. See Fig. 61 . Remove brake hose from rear brake caliper. 5. Tighten the bleed nipple and remove the bleeder tube and bottle. Remove and discard the rear brake caliper retaining bolts. See Fig. 62 . Remove the caliper. 6. Clean and inspect all associated parts. Installation CAUTION: Retracting the caliper piston may cause the fluid reservoir to overflow. Remove brake fluid spillage immediately from paint work with clean water. NOTE: The left rear brake caliper piston retracts counterclockwise and the right rear caliper piston retracts clockwise. 1. Using the Brake Caliper Piston Retractor Tool (206-080) and Crankshaft Pulley/Damper Remover (303- 588), fully retract the rear brake caliper piston into the caliper housing. See Fig. 64 . NOTE: Make sure the piston location mark is in the correct position so that the

1. Remove master cylinder fluid reservoir cap. 2. Raise and support vehicle. 3. Remove tire and wheel assembly. CAUTION: DO NOT overtighten C-clamp. 4. Place appropriately sized C-clamp over brake caliper, placing screw-drive head against outboard shoe and hook against rear of caliper. Slowly tighten screw-drive retracting caliper pistons into bores and brake outboard brake shoe free from caliper fingers. See Fig. 22 . Remove C-clamp. 5. Once outboard shoe is free from caliper fingers, slide caliper inboard on guides providing clearance between the rotor and inboard brake shoe. 6. Slide an appropriate prying tool through center opening in top of caliper behind brake shoe between 2 caliper pistons. Use care not to come in contact with pistons or dust boots potentially damaging them. Pry against rear of inboard brake shoe braking it free from caliper pistons. 7. Remove the 2 brake caliper guide pin bolts. See Fig. 23 . 8. Remove disc brake caliper from brake adapter and hang out of way using wire or a bungee cord. Use care not to overextend brake hose when doing this. 9. Remove brake shoes from disc brake caliper adapter. See Fig. 27 . 10. Install master cylinder fluid reservoir cap. Installation (Front) 1. Place brake shoes in anti-rattle clips on adapter. See Fig. 27 . Make sure clips are properly installed. See Fig. 26 . 2. Install disc brake caliper over brake shoes on brake caliper adapter. See CALIPER . 3. Align guide pin bolt holes with guide pins and install caliper guide pin bolts. See TORQUE SPECIFICATIONS . 4. Install tire and wheel assembly. See TORQUE SPECIFICATIONS . 5. Lower vehicle. 6. Pump brake pedal several times to seat shoes to caliper and brake rotor. 7. Check and fill brake fluid level as necessary. See CHECKING & FILLING under BRAKE FLUID in SERVICE. 8. Road test vehicle making several stops to wear off any foreign material on brakes and to seat brake shoes.

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.

Front Pad Removal Before replacing the pads, inspect the master cylinder to ensure that it has not been topped off before retracting the pistons into the caliper bores. The front brakes are a floating dual-piston caliper type, the pistons are phenolic. The caliper bridge bolts have a guide pin and bolt that attach the caliper to the bracket. Removing the bottom bolt allows the caliper to be pivoted out of the bracket. Using a special piston retractor designed to push evenly on the dual pistons is highly recommended. The pads are retained in the bracket with anti-rattle clips. To release the pad from the clip, there are tabs at the ends of pad that are depressed to release the pad. The pads have noise dampening material attached to the back of the pads. Front Pad Install Inspect the dust boots for damage and replace if necessary. Inspect the guide pins and replace and lubricate if necessary. The boot is to be seated in the grooves of the caliper bracket and guide pin. Install new anti-rattle clips and pads, rotate the caliper and align the flats on the guide pin to the mounting ear of the caliper. Torque the guide pin bolts to 64 Nm (30 ft/lbs). The caliper bracket bolts on this vehicle use high strength thread locker to hold it in place (it is the “red stuff”). Make sure to clean the old thread locker material off the threads with denatured alcohol before putting new thread locker on. The bolts should be tightened to a whopping 129 ft/lbs! Rear Pads Inspect the dust boots for damage and replace the caliper if necessary. Inspect the guide pins and replace and lubricate if necessary. The boot is to be seated in the grooves of the caliper bracket and guide pin. Install new anti-rattle clips and pads rotate the caliper and align the flats on the guide pin to the mounting ear of the caliper. Torque the guide pin bolts to 64 Nm (30 ft/lbs). Like in the front, the rear caliper brackets use thread locker. Make sure to clean threads. Then torque the bolts to 148 ft/lbs. Rotor and Hub Inspection Specifications: Front Brakes

Remove two-thirds of the brake fluid from the master cylinder. Raise the vehicle and suitably support. Refer to Vehicle Lifting. Mark the relationship of the wheel to the hub flange. Remove the Wheel. Refer to Tire and Wheel Removal and Installation in Wheels, Tires and Alignment. Important: Do not use a screwdriver or pry bar to compress the caliper piston into the caliper. Any damage to the piston boot could cause corrosive elements to enter the piston sealing area and lead to the piston seizing in the caliper bore. Important: Do not exceed more than 1 mm of piston travel. Damage to the internal adjusting mechanism may result. 5. Using a large C clamp compress the piston into the caliper until resistance is felt, but no more than 1 mm of piston travel in order to gain enough clearance to allow the caliper to pivot off the caliper bracket. 6. Disconnect the park brake cable (1) from the brake caliper. 7. 8. 9. 10. Remove the bottom caliper slide pin. Pivot the caliper body (6) upward. Remove the inboard (2) and outboard (3) pads from the anchor bracket (5). Remove and inspect the pad retainers (1). Important: Inspect the caliper bolt suspension boots for cuts, tears, or deterioration. if damaged, replace the pin boots. Refer to Caliper Bracket Overhaul. Inspect the piston boot for deterioration. If damaged, Refer to Caliper overhaul. Caliper pin bolt for damage or corrosion. Replace if damaged or corroded. Do not attempt to clean away corrosion. Corrosion is typically caused by damaged pin boots. Installation Procedure
