Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety gloves and goggles.

2. Wheel Removal

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

3. Brake Inspection

Sub-steps:
1. Inspect the brake rotor surface for any signs of warping or scoring. Use a straightedge to check for flatness.
2. Measure the rotor thickness with a micrometer to ensure it meets specifications.
3. Check brake pad thickness; replace if below manufacturer specifications (typically 3mm).
Tools Required: Micrometer, straightedge.

4. Rotor Replacement (if necessary)

Sub-steps:
1. Remove the caliper by unbolting it from the bracket; hang it using a bungee cord to avoid straining the brake line.
2. Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.
3. Install the new rotor onto the hub, ensuring it is seated properly.
Tools Required: Socket set, screwdriver.

5. Brake Pad Replacement (if necessary)

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Compress the caliper piston using a caliper tool to make room for the new pads.
3. Install the new brake pads in the caliper bracket, ensuring they are correctly positioned.
Tools Required: Brake caliper tool.

6. Reassembly

Sub-steps:
1. Reattach the caliper to the bracket and secure it with bolts.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and then torque the lug nuts to the manufacturer’s specification.
Tools Required: Torque wrench.
