Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake caliper tool, socket set, torque wrench, brake cleaner, and safety goggles.
Parts Required: Brake caliper rebuild kit or replacement caliper, brake fluid.
Safety Warnings: Always wear safety goggles and gloves. Ensure the vehicle is on a flat surface and secured with jack stands before beginning work.

2. Remove Wheel

Loosen the lug nuts on the affected wheel using a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Remove Brake Caliper

Inspect the brake caliper for visible damage or corrosion.
Remove the caliper mounting bolts using the appropriate socket.
Carefully slide the caliper off the brake rotor. Support it with a bungee cord or similar to avoid straining the brake line.

4. Rebuilding or Replacing the Caliper

If Rebuilding:

Use a caliper tool to retract the piston fully.
Remove the piston and seal from the caliper housing.
Clean the caliper and piston thoroughly with brake cleaner.
Install the new seal and lubricate it with brake fluid.
Reinsert the piston into the caliper.

If Replacing:

Remove the brake line from the old caliper, being cautious of brake fluid spillage.
Install the new caliper by reversing the removal process.
Tighten the brake line securely to the new caliper.

5. Reassemble and Test

Reattach the brake caliper to the rotor and secure it with the mounting bolts. Torque to manufacturer specifications (typically around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to ensure even tightening.
