Diagnostic Steps

1
Inspect brake pads for wear; measure thickness to determine if they are worn beyond specification.
2
Check brake rotors for scoring or warping; use a micrometer to measure rotor thickness.
3
Examine brake calipers for sticking or seized components.
4
Inspect brake lines for leaks or damage.
5
Check for proper brake fluid level and condition.

Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully lift the caliper off the rotor and secure it with a bungee cord or similar to avoid stress on the brake line.
- Check the brake pads for thickness; replace if less than 3mm.
Replace Brake Pads:
- Remove old pads from the caliper bracket.
- Install new pads, ensuring they are properly seated.
- Apply brake grease to the backing of the pads to prevent noise.

4. Inspect and Resurface or Replace Rotors

Inspect Rotors:
- Check for deep grooves or warping. If warped, consider resurfacing or replacing.
Resurface Rotors (if applicable):
- Take rotors to a machine shop for resurfacing or use a brake lathe if available.
Replace Rotors (if needed):
- Remove caliper bracket by loosening the bolts.
- Slide the rotor off and install a new rotor, securing it with the caliper bracket bolts.

5. Reassemble and Test

Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s specified torque (usually around 20 ft-lbs).
Replace the wheel and lug nuts; torque the lug nuts to specifications (typically 80-100 ft-lbs).
Reconnect the negative battery terminal.
