Diagnostic Steps

1
Inspect brake fluid level in the master cylinder reservoir.
2
Check for visible leaks in brake lines, hoses, and around wheel cylinders.
3

4
Inspect the brake master cylinder for signs of failure or leakage.
5

Solution

1. Preparation

Tools Required: Socket set, wrench set, brake fluid, brake line wrench, OBD-II scanner
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Top Off Brake Fluid

Open the hood and locate the brake master cylinder reservoir.
Remove the cap and check the brake fluid level; if low, top off with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).

3. Check for Leaks

Visually inspect the brake lines and hoses for cracks, corrosion, or wet spots.
If any leaks are found, replace the damaged brake line or hose using a line wrench for better grip.

4. Inspect Brake Components

Remove the wheel for better access to the brake components.
Check brake pads for thickness; replace if they are worn beyond the manufacturer's specifications.
Inspect the caliper for any fluid leakage and ensure it operates smoothly.

5. Replace Master Cylinder (if necessary)

If the master cylinder is leaking or not functioning properly, remove it by:
- Disconnecting the brake lines (use a line wrench).
- Unbolting the master cylinder from the brake booster.
Install the new master cylinder by reversing the removal process, ensuring to torque the bolts to the manufacturer's specifications.

6. Bleed the Brake System

Using a brake bleeder kit, bleed the brake lines to remove air:
- Start with the wheel furthest from the master cylinder (usually the right rear).
- Have an assistant press the brake pedal, and open the bleeder valve until fluid flows out without air bubbles.
- Repeat for the left rear, right front, and left front wheels.
Ensure the brake fluid level remains adequate during this process.
