Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery negative terminal for safety.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid tester, fluid catch container
- Open the brake fluid reservoir cap.
- Use a brake fluid tester to check the fluid quality.
- If contaminated or low, siphon out old brake fluid using a fluid catch container.
- Refill with the manufacturer-recommended brake fluid (e.g., DOT 4).

3. Check and Repair Brake Lines

Tools Required: Wrench set, pliers
- Inspect all brake lines and hoses for any signs of corrosion or leaks.
- Tighten any loose connections found during inspection.
- Replace any damaged brake lines or hoses with new ones.

4. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench
- Remove the wheel to access the brake caliper and rotor.
- Inspect the brake pads for wear; replace if they are below the minimum thickness.
- Check the brake rotor for grooves or warping; replace if necessary.
- Reassemble the braking system, ensuring all bolts are tightened to the manufacturer’s specifications.

5. Check and Replace Master Cylinder (if necessary)

Tools Required: Socket set, brake fluid catch container
- If leaks are found at the master cylinder, remove it from the brake booster.
- Replace with a new master cylinder, ensuring all connections are secure.
- Bleed the brake system to remove any air pockets.

6. Final Assembly and Testing

Tools Required: Torque wrench
- Reinstall the wheel and lower the vehicle.
- Reconnect the battery terminal.
- Pump the brake pedal to build pressure and check for firmness.
- Test drive the vehicle at low speeds to confirm proper braking function.
