Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, dial indicator, caliper, brake cleaner.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Remove Wheels

Loosen the lug nuts with a lug wrench.
Use a jack to lift the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheels to access the brake components.

3. Inspect and Replace Brake Rotors

Sub-steps:
1. Use a dial indicator to check if the rotors are warped; replace if runout exceeds manufacturer specifications.
2. Remove the brake caliper by unscrewing the caliper bolts; support it with a bungee cord to avoid strain on the brake line.
3. Unscrew the rotor from the hub (if applicable) and replace it with a new rotor, ensuring it is clean and free of debris.
4. Torque the rotor bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Pads

Sub-steps:
1. Check the thickness of the brake pads; if they are below the minimum thickness, replace them.
2. Remove old pads from the caliper bracket.
3. Install new brake pads, ensuring they are positioned correctly.
4. Apply brake grease to the backing of the pads to reduce noise.

5. Reassemble and Test

Sub-steps:
1. Reinstall the brake caliper and torque the caliper bolts to the specified value.
2. Reinstall the wheels and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
4. Reconnect the battery and pump the brake pedal to seat the pads.
