Diagnostic Steps

1
Inspect brake pads for uneven wear and thickness.
2
Check rotor condition for warping or scoring with a dial indicator.
3
Verify brake caliper function and inspect for sticking or binding.
4
Check wheel alignment and tire pressure.

Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Pads

Remove Wheel:
- Use a lug wrench to loosen and remove the wheel lug nuts.
- Lift the vehicle with a jack and secure with jack stands.
Remove Caliper:
- Remove the caliper mounting bolts using a socket set.
- Slide the caliper off the brake rotor and secure it with a bungee cord to avoid stress on the brake line.
Check Brake Pads:
- Inspect pads for uneven wear; replace if thickness is below specification (typically 3mm).
- Use a wire brush to clean the caliper bracket and mounting surface.
Install New Brake Pads:
- Apply brake grease to the back of new pads to prevent squeaking.
- Install new pads into the caliper bracket.

3. Inspect and Resurface/Replace Rotors

Check Rotor Thickness:
- Use a micrometer to check thickness; if below minimum specification, replace rotors.
Resurface Rotors:
- If rotors are within specifications but warped, take them to a machine shop for resurfacing.
Install Rotors:
- If replacing, install new rotors onto the hub and tighten to manufacturer specifications.

4. Reassemble Braking System

Reattach Caliper:
- Slide the caliper back over the new pads and rotor.
- Tighten mounting bolts to specified torque.
Reinstall Wheel:
- Place the wheel back onto the hub and hand-tighten lug nuts.
- Lower the vehicle and torque lug nuts to manufacturer specifications.

5. Test Brake System

Start the vehicle, pump the brake pedal to ensure proper engagement, and check for any unusual noises.
