Diagnostic Steps

1

2
Check brake pad thickness to ensure they are within safe limits.

Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, torque wrench, dial indicator, and basic hand tools.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the braking system.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Use a dial indicator to measure rotor runout. If it exceeds manufacturer specifications, replace the rotors.
Replace Rotors:
- Remove caliper bolts to detach the caliper from the rotor.
- Hang the caliper using a wire or bungee to avoid straining the brake line.
- Remove the old rotor and install a new rotor, ensuring it is seated correctly.
- Reinstall the caliper and torque bolts to specification (typically 20-30 ft-lbs).

4. Inspect and Replace Brake Pads

Check the brake pads for wear; if less than 3mm thick, replace them.
Remove old pads from the caliper bracket and install new pads, ensuring proper alignment.
Apply brake grease to the backing of the pads to prevent noise.

5. Reassemble and Torque Wheels

Reinstall the wheel and tighten lug nuts by hand.
Lower the vehicle and torque the lug nuts to manufacturer specifications (typically 76-80 ft-lbs).
