Symptoms

•Brake pedal feels soft and goes to the floor when pressed
•Reduced braking effectiveness or 'spongy' brake feel
•Warning lights illuminated on the dashboard (e.g., brake warning light)
•Possible fluid leakage under the vehicle
•Increased stopping distance

Diagnostic Steps

1
Inspect brake fluid level in the master cylinder reservoir.
2
Check for visible leaks in brake lines, calipers, and master cylinder.
3
Scan for error codes using an OBD-II scanner to identify any electronic brake system faults.
4
Inspect the condition of brake pads and rotors for wear or damage.
5
Test for air in the brake lines by performing a brake pedal pump test.

Solution

Diagnostic Steps

2
Check for visible leaks in brake lines, calipers, and master cylinder.
3
Scan for error codes using an OBD-II scanner to identify any electronic brake system faults.
4

Solution

1. Preparation

Gather tools: socket set, brake fluid, bleed kit, OBD-II scanner.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Remove the cap from the master cylinder reservoir.
Inspect 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. Locate and Repair Leaks

Visually inspect all brake lines, calipers, and the master cylinder for leaks.
If a leak is found, replace the damaged component (e.g., brake line, caliper).
Tighten any loose fittings or connections.

4. Bleed the Brake System

Attach a brake bleeding kit to the bleeder valve on each brake caliper.
Start with the caliper furthest from the master cylinder (usually the passenger rear).
Have an assistant press the brake pedal while you open the bleeder valve to release air and fluid.
Close the valve before the assistant releases the pedal. Repeat until no air bubbles are visible.
Repeat for all calipers in the correct order (passenger rear, driver rear, passenger front, driver front).

5. Recheck Brake System

After bleeding, check the brake fluid level and top off if necessary.
Test the brake pedal for firmness before taking the vehicle for a test drive.
