Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes need inspection.
Secure the vehicle with jack stands.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Inspect the wheel hub area for any visible obstruction that may affect the brake system.

4. Inspect and Service Brake Components

Caliper Inspection:
- Remove the caliper bolts using a socket wrench.
- Check the caliper for proper movement and any signs of rust or corrosion.
- If stuck, clean the caliper slide pins and apply silicone grease.
Brake Pad and Rotor Inspection:
- Remove the brake pads and check for wear; replace if less than 3mm thick.
- Measure the rotor thickness; replace if below manufacturer specifications.

5. Reassemble

Reinstall the brake pads and caliper. Ensure all bolts are torqued to the manufacturer's specifications (typically around 20-30 lb-ft for caliper bolts).
Reinstall the wheel and lug nuts, torquing them to specification (usually around 76 lb-ft).

6. Brake Fluid Check

Inspect the brake fluid reservoir; if low or dirty, replace the brake fluid using DOT 3 or DOT 4 brake fluid.

7. Test Drive

Lower the vehicle, reconnect the battery, and perform a test drive to ensure proper brake function and check for dragging symptoms.
