Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent the vehicle from rolling.

2. Lift the Vehicle

Sub-steps:
1. Loosen the lug nuts on the front wheels slightly while the vehicle is on the ground.
2. Use a hydraulic jack to lift the front of the vehicle.
3. Secure it with jack stands and remove the front wheels.
Tools Required: Hydraulic jack, jack stands, lug wrench.

3. Inspect and Clean Brake Components

Sub-steps:
1. Remove the brake caliper by unbolting it from the bracket.
2. Inspect the brake pads for wear; replace if they are below the manufacturer’s specifications.
3. Check the caliper piston for any signs of seizing; clean or rebuild if necessary.
4. Inspect the brake rotor for warping or damage; resurface or replace if required.
5. Clean the caliper bracket and sliding pins to ensure free movement.
Tools Required: Socket set, brake cleaner, wire brush.

4. Replace or Adjust Components

Sub-steps:
1. If necessary, replace the brake pads, ensuring they are compatible with the vehicle.
2. Reinstall the caliper and torque the bolts to the manufacturer’s specifications (typically 20-30 ft-lbs).
3. If the brake lines are damaged, replace them with new lines and bleed the brake system.
Tools Required: Torque wrench, replacement brake pads, brake lines if needed.

5. Reassemble and Lower the Vehicle

Sub-steps:
1. Reattach the front wheels and hand-tighten the lug nuts.
2. Lower the vehicle to the ground and fully tighten the lug nuts in a crisscross pattern.
3. Recheck the brake fluid level and add fluid if necessary.
Tools Required: Torque wrench, lug wrench.
