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.

Brake Noise: A squeak, squeal, clunk, or groan that occurs when the brakes are applied or released. b. Brake Judder: A vibration that can be felt in the vehicle, steering wheel, or brake pedal when the brakes are applied. c. Pedal Feel: The effort needed to operate the brakes is too high or too low. SERVICE PROCEDURE 1. Verify the condition by road testing the vehicle with the customer. 2. Determine the specific brake issue based on the description in the Service Information above. 3. Follow the appropriate repair procedure(s), listed on the following pages, for your specific issue. BRAKE NOISE • Brakes can make a range of noises when applied or released. Some noises are normal and no repair action should be taken. • Use the following descriptions to identify the specific type of brake noise and the appropriate repair: Squeak noise when the brakes are cold: • Usually occurs during the first few stops in the morning. • This is a normal condition. No service action is necessary Squeak noise with the brakes at normal operating temperatures: • Refer to technical bulletins specific to the model of vehicle regarding this issue. • If there are no bulletins for the car you are working on, install OE type pads using the information listed under Brake Service on page 5 of this bulletin and the appropriate Service Manual procedures. Notes about brake pads and brake noise: Original Equipment (OE) brake pads are installed on all current Infiniti vehicles at the factory. • The OE pads use a Non-asbestos Organic (NAO) compound.
