Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen lug nuts on the front wheels slightly while the car is on the ground.
2. Raise the vehicle using the jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake cleaner, C-clamp
Sub-steps:
1. Remove the caliper bolts with a socket and carefully slide the caliper off the rotor.
2. Use a C-clamp to compress the caliper piston back into its housing.
3. Remove the old brake pads from the caliper bracket.
4. Clean the caliper bracket and install new brake pads, ensuring they are properly seated.

4. Check and Resurface/Replace Brake Rotors

Tools Required: Torque wrench, dial indicator, rotor measuring tool
Sub-steps:
1. Inspect the rotors for signs of warping or damage; measure with a dial indicator.
2. If warped, decide to either resurface or replace the rotors.
3. If resurfacing, ensure rotor thickness is within manufacturer specifications; if replacing, install new rotors.

5. Reassemble and Torque Components

Tools Required: Torque wrench
Sub-steps:
1. Reattach the caliper over the new brake pads and torque the caliper bolts to the manufacturer’s specifications.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to the specified value.
