My rotors, brakes or calipers are making this very high pitched noise but only have some time of driving, with the turn of the wheel, even just a little and after hitting bumps… it stops when i hit the brakes. I have a video of the noise if theres a way to share that
Generally if the noise stops when the brake pedal is applied it means you need to have the brakes serviced. Simple put, you need the brake pads replaced at a minimum. I recommend replacing the rotors at the same time you have the brake pads replaced.
Brake Pads, Replace
Front
Removal
Do not disconnect brake hose from caliper body assembly.
1. Raise and support vehicle and then remove front wheels.
2. Remove caliper bolt on lower side.
3. Raise caliper body assembly and support it, see image.
4. Remove brake pads from caliper bracket, see image.
Installation
Ensure to install so that pad return spring faces input side of direction of brake rotor rotation.
Correctly install pad return spring to supporting surface of pad retainer.
If pad return spring is deformed or damaged, replace brake pad with a new component.
Before installation, remove mud and foreign matter from caliper body assembly and support.
Install brake pad indicator in proper direction.
1. Inspect brake pad.
2. Apply a thin coat of grease to pad retainer, see image.
3. Apply a thin coat of grease to pad and both sides of shim, disc brake front inner (a), see image.
4. Install brake pad to bracket.
5. Install caliper body assembly to support. Torque caliper bolt to 20 ft. lbs.
6. Install front wheel and tire assemblies. Torque wheel nuts; except for C4 model to 89 ft. lbs. and C4 model to 74 ft. lbs.
Inspection
Wear indicators are installed on inner and outer disc brake pads.
If pad is worn to limit, end of wear indicator contacts disc rotor and a squeaking sound is heard as wheel rotates. If sound is heard, replace pad.
Always replace pads of both wheels and both sides as a set.
Replace pad retainers if they are twisted or worn.
Replace pad if there is oil or grease on it.
1. Inspect pad thickness. Standard .43 inch, Wear limit .059 inch.
2. If wear limit is exceeded in inspection, replace brake pad.
