Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Brake Inspection and Replacement

Sub-steps:
1. Remove the wheel by loosening the lug nuts and using a jack to lift the vehicle.
2. Remove the brake caliper by unscrewing the caliper bolts and sliding it off the rotor.
3. Take off the brake rotor by removing any retaining screws or clips.
4. Inspect the brake pads for wear. If they are worn down to the indicator, replace them.
5. Clean the brake components with brake cleaner and inspect the caliper for any leaks.
6. Reinstall the new brake rotor and pads, ensuring all components are properly aligned.
7. Reattach the caliper and make sure to torque the caliper bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).
8. Reinstall the wheel and lower the vehicle.

3. Drivetrain Component Inspection

Sub-steps:
1. Inspect CV joints for cracks or damage, replacing if necessary.
2. Check the axle for any signs of play or wear; replace if damaged.
3. Ensure all suspension components are secure and not worn out.
4. Reassemble any components removed during inspection.
