Solution

1. Preparation

Gather all necessary tools and parts.
Safely park the vehicle on a level surface and engage the parking brake.
Use a jack to lift the vehicle and secure it with jack stands.

2. Remove Wheel

Using a lug wrench, loosen and remove the wheel lug nuts.
Carefully remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Inspect: Check the brake rotors for warping or scoring. Use a dial indicator to measure runout.
Replace: If warped, remove the caliper assembly by unbolting it and hanging it securely to avoid stressing the brake line.
- Tools Required: Socket set, torque wrench
- Warning: Use caution when handling brake components to avoid injury.
Install New Rotors: Place the new rotors onto the hub, ensuring they seat properly.

4. Inspect and Replace Brake Pads

Remove old brake pads from the caliper bracket.
Inspect: Check for uneven wear or damage to the pads.
Replace: Install new brake pads, applying brake grease to the backing plate.
- Tools Required: Brake pad spreader, torque wrench
Torque Specification: Caliper bolts should be torqued according to manufacturer specifications (check the owner's manual).

5. Reassemble and Reinstall Wheel

Reattach the caliper assembly and ensure all bolts are tightened to specifications.
Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern to ensure even pressure.
