Diagnostic Steps

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

4
Inspect brake pads and rotors for wear and damage.
5

Solution

1. Preparation

Gather tools and parts: OBD-II scanner, brake fluid, socket set, torque wrench, brake line wrench, and replacement components if needed.
Ensure the vehicle is on a flat surface and securely lift it using jack stands if necessary.

2. Inspect and Top Off Brake Fluid

Remove the cap from the master cylinder reservoir.
Check the fluid level; if low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Replace the cap securely.

3. Check for Leaks

Visually inspect all brake lines, hoses, and connections for signs of leakage.
If leaks are found, replace the affected components and ensure all connections are tight.

4. Inspect Brake Components

Remove the wheel to access the brake caliper and rotor.
Examine the brake pads for wear; replace if worn below the minimum thickness.
Inspect the brake rotors for grooves or warping; replace if necessary.
Reinstall the wheel and torque lug nuts to manufacturer's specifications.

5. Test Brake Booster

With the engine running, press the brake pedal several times to deplete vacuum assist.
Hold the pedal down; if it sinks to the floor, the brake booster may be faulty.
Replace the brake booster if necessary.

6. Check Master Cylinder

If previous steps did not solve the issue, remove the master cylinder.
Inspect for signs of internal failure (e.g., discoloration or debris in fluid).
Replace the master cylinder if found defective, ensuring to bleed the brake system afterward.
