Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Raise the vehicle using a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Rotors

Inspect Rotors: Use a dial indicator to check for warpage; if warped beyond manufacturer specifications, replace.
Remove Calipers: Unbolt the caliper using a socket wrench and hang it with a bungee cord to avoid straining the brake line.
Remove Old Rotors: Unbolt and remove the old rotors. Clean the hub surface.
Install New Rotors: Place new rotors onto the hub and torque the bolts to manufacturer specifications (typically around 80-100 ft-lbs).

4. Inspect and Replace Brake Pads

Remove Old Pads: Slide out the old brake pads from the caliper bracket.
Install New Pads: Place new brake pads into the caliper bracket. Ensure they are properly seated.
Reattach Caliper: Reposition the caliper over the new pads and secure it with bolts, torquing as specified.

5. Reassemble and Test

Reattach the wheel and lug nuts, and lower the vehicle.
Torque the lug nuts to the manufacturer's specification (typically 100-150 ft-lbs).
Pump the brake pedal to seat the pads against the rotors.
Test drive the vehicle to ensure proper brake operation.
