Sometimes, your GM vehicle?s brakes will alert you when there?s trouble. Whistling noises, chirping sounds or grinding are indications that maintenance is required. Here are some common causes of brake noise.
- Worn brake pads
- Heat cracked or worn "un-true" rotors
- Rough finish on resurfaced rotors
- Loose fitting brake pads in the caliper
- Lack of silicone compound on back of brake pad
- Missing springs or anti-rattle clips that should be on the caliper or pad
- Improper tightening sequence of lug nuts or caliper hardware
Vehicles often come equipped with a small thin piece of metal attached to the brake pad to act as a warning indicator when the pad material is getting low and the brake pads should be replaced. This device makes a loud noise on brake application, letting you know it is time to have your brakes serviced.
