Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and set the parking brake.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle depending on which calipers are being inspected.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Carefully take off the wheel to access the brake calipers.

4. Inspect Calipers

Visual Inspection: Check for leaking brake fluid and any signs of corrosion.
Physical Inspection: Press the brake pedal and observe the caliper movement; it should move smoothly.
Check Pads: Inspect the brake pads for even wear and sufficient thickness.

5. Replace Calipers (if necessary)

Remove the Brake Caliper:
- Unscrew the bolts securing the caliper to the bracket using a socket set.
- Carefully slide the caliper off the brake rotor.
Install New Caliper:
- Position the new caliper over the rotor and align it with the bracket.
- Reinsert and tighten the caliper bolts to the manufacturer’s torque specifications (usually around 25-35 ft-lbs, but check service manual).
Connect Brake Line:
- If the caliper was replaced, connect the brake line ensuring it's properly tightened to avoid leaks.

6. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).
