Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues during the repair.

2. Inspect and Replace Brake Pads

Remove Wheel
- Use a socket set to remove lug nuts and take off the wheel.
- Tools Required: Socket set, jack, jack stands.
Check Brake Pads
- Inspect the brake pads for thickness; replace if under specifications (typically less than 3mm).
- Tools Required: Caliper tool (if needed for compression).
Install New Brake Pads
- If replacement is necessary, slide new pads into place according to manufacturer specifications.
- Safety Warning: Ensure the caliper is properly reassembled and secured.

3. Inspect and Replace Brake Rotors

Remove Caliper and Rotor
- Use a socket set to remove the caliper and then the rotor.
- Tools Required: Socket set, brake cleaner.
Check for Warping
- Use a dial indicator to measure rotor runout; replace if warping is found (typically more than 0.002 inches).
Install New Rotor
- If replacement is needed, install the new rotor, ensuring it is seated correctly.
- Torque rotor bolts to manufacturer specifications.

4. Check Wheel Alignment and Balance

Inspect Tires
- Check for uneven wear patterns that may indicate alignment issues.
Perform Alignment
- Take the vehicle to a professional alignment shop if misalignment is suspected.
