Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a caliper tool.
Allow the vehicle to cool down and ensure it is parked on a level surface.
Disconnect the negative battery terminal for safety.

2. Remove Wheel and Brake Components

Loosen the lug nuts on the wheel.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.
Remove the caliper by unscrewing the caliper bolts and gently sliding it off the rotor.
Support the caliper using a bungee cord or wire; do not let it hang by the brake line.
Remove the brake pads from the caliper bracket.

3. Inspect and Clean

Inspect the brake pads for uneven wear; replace any that are excessively worn.
Check the brake rotor for grooves or warping and replace if necessary.
Clean the caliper bracket and any mounting surfaces with brake cleaner to remove debris.

4. Check and Repair Components

Inspect the caliper for sticking pistons; clean or replace as necessary.
Check the brake lines for kinks or damage; replace if needed.
Examine suspension components (like control arms and bushings) for wear; replace any worn parts.

5. Reassemble and Test

Install new or cleaned brake pads into the caliper bracket.
Slide the caliper back onto the rotor and secure it with bolts to the specified torque (typically 25-35 Nm).
Reinstall the wheel and tighten the lug nuts to the manufacturer’s specifications.
Lower the vehicle and reconnect the negative battery terminal.
