Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and protective gloves.
Safely elevate the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Remove Brake Components

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the brake caliper off the rotor and support it using a bungee cord or rope to avoid straining the brake line.
3. Remove the brake pads from the caliper bracket.
4. If necessary, remove the caliper bracket by loosening its bolts.

3. Inspect and Replace Parts

Sub-steps:
1. Inspect the brake pads; if they are worn down to less than 1/8 inch, replace them.
2. Check the rotors for deep grooves or scoring. If the surface is damaged, replace or resurface the rotors.
3. Clean the caliper bracket and rotor using brake cleaner to remove dust and debris.
4. Examine brake hardware for wear. Replace any worn clips or shims.

4. Install New Components

Sub-steps:
1. If replacing, install new brake pads into the caliper bracket.
2. Reinstall the caliper bracket if it was removed, ensuring bolts are torqued to manufacturer specifications (usually around 80-100 ft-lbs).
3. Slide the brake caliper back over the new pads and secure it with the caliper bolts, tightening to the specified torque (typically around 20-30 ft-lbs).
4. Ensure that all components are correctly aligned and that there is no binding.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).
3. Pump the brake pedal several times to ensure proper pad contact with the rotors.
4. Test drive the vehicle to confirm that the grinding noise is resolved.
