Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear tires.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Tools Required: Socket set, lug wrench
Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel.

3. Remove Brake Caliper

Tools Required: Socket set, torque wrench
Locate the caliper mounting bolts and remove them using the appropriate socket size.
Carefully slide the caliper off the brake rotor. Do not let it hang by the brake line; use a bungee cord or similar to support it.
Inspect the caliper for damage or wear that may have caused the leak.

4. Replace or Repair Caliper

If the caliper is damaged:
- Tools Required: Brake caliper rebuild kit (if applicable), brake cleaner
- Disassemble the caliper and replace seals and piston if using a rebuild kit.
If replacing the caliper:
- Tools Required: New brake caliper, brake line wrench
- Disconnect the brake line from the caliper using a brake line wrench to avoid stripping.
- Install the new caliper by connecting the brake line and ensuring it's tightened to the manufacturer's specifications.

5. Reinstall Components

Reinstall the caliper onto the rotor and secure it with the mounting bolts.
Torque the caliper bolts to the specified torque value (usually around 25-30 ft-lbs, but verify with the service manual).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Bleed the Brake System

Tools Required: Brake bleeder kit, clean brake fluid
Refill the master cylinder with the specified brake fluid.
Start bleeding the brakes from the caliper furthest from the master cylinder, usually the right rear, then left rear, right front, and finally left front.
Ensure there are no air bubbles in the brake fluid by continuously checking the fluid level in the master cylinder.
