Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent vehicle movement.

2. Wheel Removal

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

3. Inspect and Replace Brake Rotors

Tools Required: Brake rotor tool, torque wrench
Sub-steps:
1. Inspect the brake rotors for warping by checking for uneven surfaces. Replace if warped beyond specifications.
2. If replacing, remove the caliper by unscrewing the caliper bolts and safely hanging it without straining the brake line.
3. Remove the old rotor by loosening the retaining screws (if applicable) and sliding it off.
4. Install the new rotor, ensuring it is seated correctly and secure with screws.
5. Reinstall the caliper and torque bolts to manufacturer specifications.

4. Inspect and Replace Brake Pads

Tools Required: Brake pad tool, torque wrench
Sub-steps:
1. Remove the brake pads from the caliper bracket.
2. Check for uneven wear; replace if necessary.
3. Install new brake pads, ensuring they are correctly positioned in the caliper bracket.
4. Compress the caliper piston using a brake pad tool to allow space for new pads.
5. Reinstall the caliper over the new pads and torque bolts to manufacturer specifications.

5. Reinstall Wheel and Lower Vehicle

Tools Required: Torque wrench
Sub-steps:
1. Place the wheel back onto the hub.
2. Hand-tighten the lug nuts before lowering the vehicle.
3. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
