Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the negative battery terminal.
Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.

2. Remove Wheel

Loosen the lug nuts while the vehicle is on the ground.
Raise the vehicle using a jack and secure with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Service Caliper

Visual Inspection: Check for leaks and cracks on the caliper body. If damaged, replace the caliper.
Caliper Movement: Remove the caliper bolts using a socket wrench and slide the caliper off the bracket. Inspect the caliper piston for corrosion or debris.
Piston Cleaning: If the piston is sticking, clean it with brake cleaner. If it doesn’t retract smoothly, replace the caliper.

4. Replace Brake Pads (if necessary)

Remove old brake pads from the caliper bracket.
Install new brake pads ensuring they are correctly positioned.
Use brake lubricant on the pad backing to reduce noise.

5. Reassemble Components

Slide the caliper back onto the bracket and secure it with the caliper bolts. Use the manufacturer’s torque specifications for proper tightening.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

6. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal a few times to ensure proper caliper operation and brake engagement.
