Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, protective gloves, safety goggles.
Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.
Loosen lug nuts slightly before lifting the vehicle.

2. Lift Vehicle and Remove Wheel

Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a lug wrench.

3. Inspect and Remove Brake Caliper

Inspect the brake caliper for any signs of wear or damage.
If the caliper is leaking or damaged, use a wrench to remove the caliper mounting bolts.
Carefully slide the caliper off the rotor and hang it using a bungee cord or wire, avoiding stress on the brake line.

4. Replace or Repair Caliper

If replacing:
1. Remove the old caliper and install the new one, ensuring it is properly aligned.
2. Torque the caliper mounting bolts to the manufacturer’s specifications (usually around 25-30 lb-ft).
If repairing:
1. Remove the piston by carefully prying it out with a caliper tool.
2. Inspect the piston and seals for damage; replace if necessary.
3. Clean the caliper housing and apply brake grease to the new seals before reinstallation.

5. Reassemble and Refill Brake Fluid

Reinstall the brake caliper and ensure all bolts are securely fastened.
Reattach the wheel and torque the lug nuts to the manufacturer’s specifications (typically around 80-100 lb-ft).
Refill the brake fluid reservoir with new DOT-approved brake fluid.

6. Bleed Brake System

Use a brake bleeder kit to remove air from the brake lines. Start from the wheel farthest from the master cylinder (right rear, left rear, right front, left front).
Ensure the brake fluid reservoir doesn't run dry during bleeding.
