Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, dial indicator, torque wrench, brake cleaner.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery if working with electronic brake components.

2. Remove Wheels

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure with jack stands.
Completely remove lug nuts and take off the wheels.

3. Inspect Brake Components

Rotors: Check for warping using a dial indicator; replace if runout exceeds manufacturer specifications (usually 0.002 inches).
Pads: Measure thickness; replace if below 3mm or if unevenly worn.
Clean: Use brake cleaner to remove dust and debris from rotors and pads.

4. Replace Rotors (if necessary)

Remove the caliper by unbolting it from the bracket.
Slide the caliper off the rotor and secure it to avoid stress on the brake line.
Remove the old rotor and install the new rotor.
Reinstall the caliper over the new rotor and torque bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheels and hand-tighten lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Reconnect the battery and check the brake fluid level, topping up if necessary.
