Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, socket set.
Ensure the vehicle is on a flat surface, and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Loosen lug nuts on the wheel where the brake issue is observed.
Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads and Rotors

Inspect: Check the thickness of the brake pads and the surface of the rotors for grooves or scoring.
Replace Pads (if needed):
- Remove the caliper bolts using a socket wrench.
- Carefully lift the caliper and support it without stressing the brake line.
- Remove the old brake pads.
- Install new brake pads, ensuring they are seated correctly.
Replace Rotors (if warped):
- Remove the caliper bracket if replacing rotors.
- Remove the old rotor from the hub and clean the surface.
- Install the new rotor, ensuring it is properly aligned.

4. Reassemble and Torque Components

Reinstall the caliper bracket and caliper, tightening bolts to the manufacturer’s specified torque settings (usually around 25-35 ft-lbs for caliper bolts).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 100-120 ft-lbs).

5. Final Inspection

Check brake fluid level in the reservoir and top off if necessary.
Reconnect the battery terminal.
Test the brakes by pushing the brake pedal a few times to ensure proper operation.
