Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pad thickness and condition for wear or damage.
3
Inspect suspension components including control arms, bushings, and tie rods for wear or play.
4
Verify wheel alignment and balance.
5
Check for any foreign debris or contamination on the rotor surface.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts on the affected wheel.
Raise the vehicle using a jack and support it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Measure rotor thickness with a micrometer; replace if below minimum specifications.
- Check for warping using a dial indicator; if warped, replace or machine the rotors.
Inspect Brake Pads:
- Check the thickness of the brake pads; replace if they are below 3 mm.
- Ensure no contaminants are present on pad surfaces.
Replace Brake Pads and Rotors (if necessary):
- Remove the caliper bolts using a socket wrench.
- Secure the caliper aside using a bungee cord, do not let it hang on the brake line.
- Remove the old pads and install new ones.
- If replacing rotors, remove the old rotor and install the new one, securing it with the rotor screws if applicable.

4. Reassemble Components

Reattach the brake caliper and tighten the caliper bolts to the manufacturer’s torque specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

5. Final Checks

Reconnect the battery.
Start the vehicle and pump the brakes to ensure proper pedal feel.
Conduct a test drive to ensure the issue is resolved.
