Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, C-clamp, brake cleaner, socket set, torque wrench, OBD-II scanner.
Raise the vehicle using a jack and support it securely on jack stands.
Remove the wheel using a lug wrench.

2. Remove Caliper

Sub-steps:
1. Locate the caliper mounting bolts and remove them using a socket set.
2. Carefully slide the caliper off the rotor. If it’s stuck, gently tap it with a rubber mallet.
3. Support the caliper with a bungee cord or wire to avoid stressing the brake line.

3. Inspect and Replace Components

Sub-steps:
1. Inspect the brake pads for wear; replace if necessary.
2. Check the caliper piston for damage or corrosion. Replace the caliper if the piston is damaged.
3. Clean the caliper mounting bracket and rotor with brake cleaner to remove any debris or dust.

4. Reassemble Caliper

Sub-steps:
1. If the caliper is being reused, compress the piston back into the caliper using a C-clamp.
2. Align the caliper over the rotor and secure it by tightening the mounting bolts to the manufacturer's specified torque (typically between 25-35 ft-lbs).
3. Reinstall the brake pads if they were removed.

5. Reconnect Components

Sub-steps:
1. Ensure the brake line is securely connected and free from leaks.
2. Reinstall the wheel and tighten the lug nuts to the manufacturer’s specifications.

6. Test the Brake System

Sub-steps:
1. Lower the vehicle from the jack stands.
2. Pump the brake pedal several times to ensure proper brake engagement.
3. Test drive the vehicle at low speeds to confirm the brakes are functioning correctly.
