Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety goggles and gloves.

2. Wheel Removal

Tools Required: Socket set, torque wrench
Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Brake Inspection

Inspect the brake rotors for warping by checking for any visible grooves or uneven surfaces.
Sub-step: Use a dial indicator to measure rotor runout; it should be within the manufacturer's specified limits.
Check brake pads for minimum thickness; replace if below specifications.

4. Rotor Replacement (if necessary)

Tools Required: Brake cleaner, rotor removal tool (if needed)
Remove the caliper by unbolting it from the bracket.
Hang the caliper using a bungee cord to avoid stress on the brake line.
Remove the old rotor; clean the hub surface with brake cleaner.
Install the new rotor, ensuring it is seated correctly.

5. Brake Pad Replacement (if necessary)

Tools Required: C-clamp or brake caliper tool
Remove the old brake pads from the caliper bracket.
Compress the caliper piston using a C-clamp or brake caliper tool.
Install new brake pads, ensuring they are positioned correctly in the bracket.

6. Reassembly

Reattach the brake caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the appropriate specifications.
