Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Brake Rotors

Remove Wheel: Using a socket set, loosen the lug nuts and remove the wheel to access the brake assembly.
Inspect Rotors: Check for warping or uneven wear using a dial indicator or by visual inspection.
Remove Brake Caliper: Unbolt the caliper using a socket wrench, then hang it securely (do not let it dangle by the brake line).
Remove Brake Pads: Slide out the brake pads from the caliper bracket.
Remove Rotors: If warped, unbolt and remove the rotor from the hub.
Install New Rotors: Align and install new rotors, ensuring they are torqued to manufacturer specifications.

3. Replace Brake Pads

Install New Brake Pads: Insert new pads into the caliper bracket.
Reattach Caliper: Position the caliper over the new pads and secure it with bolts.
Torque Caliper Bolts: Tighten to the manufacturer's specified torque value.

4. Check Suspension and Wheel Bearings

Inspect Suspension: Look for any signs of wear or damage on components.
Test Wheel Bearings: Check for play by gripping the wheel at the 12 and 6 o'clock positions and rocking it.
Replace if Necessary: If any component is worn, replace it following manufacturer instructions.

5. Reinstall Wheel and Test Drive

Reattach Wheel: Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower Vehicle: Use a jack to lower the vehicle back to the ground.
Torque Lug Nuts: Torque the lug nuts to the manufacturer's specification in a star pattern.
