•Ensure the vehicle is properly supported before working under it.

Symptoms

•Spongy brake pedal feel when pressed
•Longer stopping distance than normal
•Brake warning light illuminated on the dashboard
•Brake fluid level low in the reservoir
•Unusual noises when braking (squeaking or grinding)

Diagnostic Steps

1
Check Brake Fluid Level: Open the hood and inspect the brake fluid reservoir for proper fluid level.
2
Inspect for Leaks: Visually inspect brake lines, calipers, and wheel cylinders for any signs of fluid leaks.
3
Scan for Error Codes: Use an OBD-II scanner to check for any related diagnostic trouble codes (DTCs).
4
Check Brake Pads and Rotors: Inspect the brake pads and rotors for wear or damage.
5
Bleed Brake System: Prepare to bleed the brake system if air is suspected in the brake lines.

Solution

Diagnostic Steps

5

Solution

1. Preparation

Gather Tools and Parts:
- Tools: Wrench set, brake bleeder kit, container for old brake fluid, safety goggles, gloves
- Parts: Brake fluid (DOT 3 or DOT 4), brake pads (if worn), brake rotors (if needed)
Safety: Ensure the vehicle is on a flat surface and securely supported with jack stands. Wear safety goggles and gloves.

2. Check and Refill Brake Fluid

Inspect Fluid Level: Remove the cap from the brake fluid reservoir.
Refill Fluid: If low, add the appropriate brake fluid (DOT 3 or DOT 4) until it reaches the "full" mark.

3. Bleed the Brake System

Locate Brake Bleeder Valves: Identify the bleeder valves on each brake caliper (starting with the farthest from the master cylinder).
Attach Bleeder Hose: Connect a clear hose to the bleeder valve and place the other end in a container to catch the old fluid.
Pump Brake Pedal: Instruct an assistant to pump the brake pedal several times and hold it down.
Open Bleeder Valve: With the pedal held down, open the bleeder valve using a wrench to allow air and fluid to escape. Close the valve before the pedal is released.
Repeat Process: Repeat the process until the fluid runs clear without bubbles. Do this for all four wheels, in the order of farthest to closest to the master cylinder.
Check Fluid Level: Continuously monitor the brake fluid reservoir level and refill as necessary during the bleeding process.

4. Inspect Brake Components

Check Pads and Rotors: Remove the wheel to access brake pads and rotors. Replace any worn pads or damaged rotors as needed.
Reassemble: Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.
