Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the negative battery cable to prevent any electrical issues.

2. Inspect and Remove Wheel

Sub-steps:
1. Remove the lug nuts using a socket wrench and take off the wheel.
2. Inspect the brake caliper for any visible leaks or damage.
3. Check the brake pads for uneven wear and thickness.

3. Remove Brake Caliper

Sub-steps:
1. Remove the caliper mounting bolts using a socket set.
2. Carefully slide the caliper off the rotor. Support it with a bungee cord or rope to avoid straining the brake line.
3. Inspect the caliper piston for any signs of corrosion or damage.

4. Service or Replace Components

Sub-steps:
1. If the caliper piston is damaged, replace the caliper with a new or remanufactured unit.
2. If servicing, clean the piston and bore with brake cleaner and install new seals if necessary.
3. Replace brake pads if they are worn beyond specifications.

5. Reinstall Brake Caliper

Sub-steps:
1. Slide the caliper back onto the rotor and ensure it aligns correctly with the brake pads.
2. Tighten the caliper mounting bolts to the specified torque (check manufacturer specifications for exact value).
3. Reattach the wheel and hand-tighten the lug nuts.

6. System Check

Sub-steps:
1. Reconnect the negative battery cable.
2. Press the brake pedal several times to seat the pads against the rotor.
3. Check brake fluid level and top off if necessary.
