Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Use wheel chocks to prevent movement.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle depending on which caliper you're inspecting.
Secure the vehicle with jack stands.
Remove the wheel to access the brake components.

3. Remove the Caliper

Remove the caliper mounting bolts using a socket set (typically 12mm or 14mm).
Carefully slide the caliper off the brake rotor without damaging the brake line.
Support the caliper with a bungee cord or rope to avoid stress on the brake line.

4. Inspect the Caliper

Examine the caliper for any signs of leaking brake fluid, rust, or physical damage.
Check the caliper piston for smooth operation by pushing it in with a C-clamp or brake tool.
If necessary, clean the caliper with brake cleaner to inspect more thoroughly.

5. Replace or Repair

If the caliper is found to be faulty, replace it with a new unit.
- Remove the old caliper and install the new one, ensuring proper alignment.
- Reattach the caliper mounting bolts and torque them to the manufacturer's specifications (typically around 25-35 lb-ft).
If servicing the caliper, replace any seals and lubricate the piston before reassembly.

6. Reassemble and Lower the Vehicle

Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.
Carefully lower the vehicle back to the ground.
