•Brake pedal travels to the floor
•Reduced braking effectiveness
•Possible brake warning light illuminated
•Fluid leakage around brake components

Diagnostic Steps

1
Inspect brake fluid level in the master cylinder reservoir.
2
Check for any visible fluid leaks in brake lines or around calipers.
3
Scan for error codes using an OBD-II scanner to identify any electronic issues.
4
Examine brake pads and rotors for wear or damage.
5
Test for air in the brake lines by performing a brake bleed procedure.
6
Inspect the brake master cylinder for internal failure.

Solution

Diagnostic Steps

Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Open the hood and locate the master cylinder reservoir.
Check the brake fluid level; it should be between the "MIN" and "MAX" marks.
If low, fill with the appropriate brake fluid type (often DOT 3 or DOT 4).
Close the reservoir cap securely.

3. Inspect for Leaks

Visually inspect all brake lines, calipers, and wheel cylinders for signs of fluid leakage.
If leaks are found, identify the source and prepare to replace damaged components (e.g., brake lines, calipers).

4. Bleed the Brake System

Locate the brake bleeder screws on each caliper.
Start with the wheel farthest from the master cylinder (usually the rear passenger side).
Attach a clear hose to the bleeder screw and submerge the other end in a container with brake fluid.
Have an assistant press the brake pedal down while you open the bleeder screw. Close the screw before the pedal reaches the floor. Repeat until no air bubbles are seen.
Repeat this process for the remaining wheels in order: rear passenger, rear driver, front passenger, and then front driver.

5. Inspect and Replace Components (if necessary)

If the pedal still feels soft, inspect the master cylinder.
If it is leaking or has internal failure, remove it by disconnecting the brake lines and unbolting it from the firewall.
Install a new master cylinder by reversing the removal process and ensuring all connections are secure.
