Solution

1. Preparation

Gather tools and materials (see Tools Required section).
Park the vehicle on a flat, stable surface and engage the parking brake.
Loosen the lug nuts on the wheel corresponding to the affected caliper.

2. Wheel Removal

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake caliper.

3. Caliper Inspection

Sub-step 1: Inspect the caliper for leaks and damage.
Sub-step 2: Check the condition of the brake pads and rotors.
Sub-step 3: Ensure the caliper bracket is secure and not damaged.

4. Caliper Replacement (if necessary)

Sub-step 1: Remove the caliper bolts using a socket set.
Sub-step 2: Slide the caliper off the rotor and hang it using a bungee cord or wire (do not let it hang by the brake line).
Sub-step 3: Remove the old brake pads from the caliper bracket.
Sub-step 4: Install new brake pads into the caliper bracket.
Sub-step 5: Compress the caliper piston using a caliper tool to fit over the new pads.
Sub-step 6: Reinstall the caliper over the new pads and secure it with bolts, tightening to manufacturer's specifications.

5. Reassembly

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the correct specification.

6. Final Checks

Refill brake fluid if necessary and bleed the brake system to remove any air.
Check for any leaks around the caliper and lines after the repair.
