Toyota reports that some 2003-07 Corolla and Matrix models may produce an irritating squeak from the front brakes when applying the pedal while moving slowly in reverse.
One likely cause for the noise, says the car maker, is the front brake pads vibrating in the caliper mounts.
Installing new-design caliper mounts (part No. 47721-02141), brake pad support plates (part No. 04947-02120) and bushing dust boots (part No. 47775-02090) should eliminate the noise.
