Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Inspect and Repair Brake Lines

Locate Leak:
- Visually inspect all brake lines and connections for signs of wear or damage.
Replace Damaged Lines:
- Use a wrench to disconnect the damaged brake line; replace with a new line.
- Ensure all connections are tight and secure; torque specifications vary by model.
Bleed the Brake System:
- Start at the farthest wheel from the master cylinder, using a brake bleeder kit.
- Repeat for all wheels until no air bubbles are present.

3. Replace Brake Fluid

Drain Old Fluid:
- Open the master cylinder reservoir and remove old fluid using a turkey baster.
Add New Brake Fluid:
- Fill the reservoir with manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Check for Leaks:
- After replacing fluid, check all connections again for leaks.

4. Inspect and Replace Brake Pads/Rotor

Remove Wheel:
- Use a jack to lift the vehicle and remove the wheel lug nuts with a socket wrench.
Inspect Pads/Rotor:
- Check the thickness of the brake pads and the condition of the rotors.
Replace if Necessary:
- If pads are worn below specifications (usually less than 3mm), replace them.
- For rotors, if warped or below minimum thickness, replace with new rotors.

5. Test Brake System

Reassemble:
- Reinstall the wheel and lug nuts; torque to specifications.
Test Drive:
- Conduct a test drive to check for proper pedal feel and braking performance.
