Solution

1. Preparation

Gather tools and materials needed for the repair.
Safety equipment: gloves and goggles.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which caliper is being inspected.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Take off the wheel to access the brake assembly.

4. Inspect the Brake Caliper

Visually inspect the caliper for any signs of leaks, cracks, or corrosion.
Check the brake pads for even wear and sufficient thickness.
Use a caliper tool to measure the remaining pad thickness; replace if below specifications (usually less than 3mm).

5. Test Caliper Movement

Apply the brakes gently while observing the caliper pistons. They should move freely without sticking.
If the caliper does not move smoothly, it may need to be serviced or replaced.

6. Replace or Service Caliper (if necessary)

If the caliper is faulty:
- Remove the caliper: Unscrew the caliper bolts using a socket set.
- Disconnect the brake line: Use a line wrench to avoid stripping the fitting.
- Install the new caliper: Reverse the removal steps, ensuring proper torque on bolts (typically 25-35 ft-lbs).
- Reconnect brake line and check for leaks.

7. Reassemble and Lower the Vehicle

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specification (usually around 80-100 ft-lbs).
