Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Lift the Vehicle

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

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.

4. Inspect and Clean Brake Components

Brake Pads and Rotors:
- Inspect brake pads for uneven wear; replace if worn beyond limits.
- Check rotors for scoring or warping; machine or replace as needed.
Calipers:
- Remove the caliper by unscrewing the caliper bolts with a socket.
- Inspect the caliper piston for movement; clean or replace if seized.
- Lubricate sliding pins and ensure they move freely.

5. Replace Brake Components (if necessary)

If pads, rotors, or calipers are worn or damaged, install new parts:
- Install new brake pads and ensure they seat correctly.
- Reinstall caliper over the pads and torque bolts to manufacturer's specifications (usually around 20-30 ft-lbs).
- Replace rotors if necessary, ensuring they are properly torqued.

6. Reassemble and Test

Reinstall the wheel and torque the lug nuts to specifications (typically 80-100 ft-lbs).
Lower the vehicle and pump the brake pedal to restore brake pressure.
Test drive the vehicle to confirm that the dragging issue is resolved.
