Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues.

2. Inspect Brake Components

Sub-steps:
- Remove the wheel to access the brake assembly using a socket set.
- Visually inspect brake pads for thickness; replace if less than 3mm.
- Check the rotors for scoring or warping; replace if necessary.

3. Check Caliper Operation

Sub-steps:
- Remove the caliper bolts using a torque wrench and slide the caliper off the rotor.
- Inspect caliper slides for corrosion or dirt; clean and lubricate with brake grease.
- Test the caliper piston movement; replace caliper if it is stuck.

4. Brake Fluid and Lines Inspection

Sub-steps:
- Check the brake fluid reservoir for proper levels; top off with manufacturer-recommended fluid if low.
- Inspect brake lines for cracks, leaks, or kinks; replace any damaged lines.

5. Reassembly and Testing

Sub-steps:
- Reinstall the caliper and wheel; torque the caliper bolts to the manufacturer's specifications.
- Reconnect the battery and perform a brake pedal test to ensure proper function.
- Test drive the vehicle at low speeds to check for dragging or abnormal braking behavior.
