Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, safety glasses, gloves.
Lift the vehicle securely using a jack and support it with jack stands. Remove the wheels.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Use a dial indicator to measure rotor run-out. If it exceeds manufacturer specifications, the rotor is warped and needs replacement.
2. If rotors are within specifications but show signs of uneven wear, consider resurfacing them if applicable.
3. If replacement is necessary, remove the caliper bracket by unscrewing the bolts and carefully lifting the caliper off the rotor.
4. Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.

3. Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Apply brake cleaner to clean the caliper bracket and remove any debris.
3. Install new brake pads in the caliper bracket, ensuring they fit snugly.
4. If necessary, compress the caliper piston using a brake caliper tool to make room for the new pads.

4. Reassemble and Adjust

Sub-steps:
1. Reinstall the rotor (if replaced) and secure it with the retaining screws.
2. Reattach the caliper bracket over the new pads and torque the bolts to the manufacturer’s specifications.
3. Reinstall the wheels and secure them with the lug nuts, torquing to manufacturer specifications.

5. Final Checks

Sub-steps:
1. Refill brake fluid if necessary and bleed the brakes to remove any air from the system.
2. Lower the vehicle and perform a test drive to ensure brakes operate smoothly without pulsation.
