Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Remove the caliper bolts and carefully slide the caliper off the rotor.
3. Remove the old brake pads from the caliper bracket.
4. Inspect new brake pads for proper fit and thickness.
5. Install new brake pads in the caliper bracket.
6. Reattach the caliper and tighten bolts to manufacturer specifications (typically around 25-30 Nm).

3. Inspect and Resurface/Replace Rotors

Sub-steps:
1. Remove the brake rotor from the hub by unscrewing any retaining screws if present.
2. Use a dial indicator to check for warping; if warped more than 0.002 inches, resurface or replace the rotor.
3. Clean the rotor surface with brake cleaner to remove dust and debris.
4. If resurfacing, ensure even thickness and smooth finish; if replacing, install the new rotor.
5. Reinstall the rotor and secure it with retaining screws.

4. Check Wheel Alignment and Balance

Sub-steps:
1. Inspect tires for uneven wear patterns and check pressure.
2. Take the vehicle to a professional alignment shop to ensure proper wheel alignment.
3. Have the tires balanced if necessary.
