Solution

1. Preparation

Gather tools and parts needed for the repair.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheels to access the brake components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the brake caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and hang it using a bungee cord (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper guide pins; clean and lubricate if necessary.
5. Install new brake pads, ensuring they are properly aligned in the caliper bracket.

3. Caliper Inspection and Repair

Sub-steps:
1. Check the caliper piston for signs of corrosion or damage.
2. If the piston is sticking, remove it and clean or replace as necessary.
3. Reinstall the caliper over the new brake pads and secure it with the bolts.

4. Rotor Inspection and Replacement

Sub-steps:
1. Inspect the brake rotor for scoring or warping; replace if necessary.
2. If the rotor is in good condition, clean it with brake cleaner to remove any debris.
3. Reinstall the wheel and torque the lug nuts to the manufacturer specifications.

5. Brake Fluid Check

Sub-steps:
1. Inspect the brake fluid reservoir for low levels; top up with the recommended brake fluid if necessary.
2. If brake fluid is contaminated, perform a brake fluid flush.
