Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, C-clamp, socket set, torque wrench.
Safety Warnings: Always wear safety glasses and gloves. Ensure the vehicle is on a level surface and properly secured on jack stands.

2. Remove the Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and securely place it on jack stands.
Remove the wheel completely to access the brake caliper.

3. Inspect and Remove the Brake Caliper

Inspect the caliper for any visible damage or leaks.
Remove the caliper mounting bolts using the socket set.
Carefully slide the caliper off the rotor. Support it using a bungee cord or hang it to avoid strain on the brake line.

4. Replace or Repair the Caliper

If replacing: Remove the old caliper completely. Install the new caliper by sliding it onto the rotor and aligning with the mounting bracket. Torque the bolts to the manufacturer's specifications (typically 20-25 ft-lbs).
If repairing: Replace any damaged seals or components inside the caliper. Clean the caliper with brake cleaner and inspect the piston for wear. Use the C-clamp to retract the piston back into the caliper.

5. Reinstall Brake Pads and Wheel

Inspect the brake pads and replace if necessary. Ensure they are seated properly in the caliper bracket.
Reinstall the caliper over the pads and rotor, securing it with the mounting bolts.
Replace the wheel and hand-tighten the lug nuts.

6. Refill Brake Fluid and Bleed Brakes

Check and refill the brake fluid reservoir as needed.
Bleed the brake system to remove any air trapped in the lines. Start from the wheel farthest from the master cylinder (usually the rear passenger side) and work toward the closest (front driver side).

7. Final Check

Replace the wheel completely, lower the vehicle, and torque the lug nuts to the manufacturer's specifications (typically 76-80 ft-lbs).
Test the brake pedal to ensure it feels firm before starting the vehicle.
