Important safety information - read before proceeding

•Brake fluid is corrosive; avoid contact with painted surfaces and wash off any spills immediately.

Symptoms

•Brake warning light illuminated on the dashboard
•Soft or spongy brake pedal feel
•Reduced braking performance or effectiveness
•Brake fluid reservoir visibly below the minimum line
•Unusual noises when pressing the brake pedal (e.g., grinding or squeaking)

Diagnostic Steps

1
Inspect the Brake Fluid Reservoir: Locate the brake fluid reservoir under the hood and visually check the fluid level against the markings on the side.
2
Check for Leaks: Look for any signs of brake fluid leaks around the brake lines, calipers, and master cylinder.
3
Examine Brake Pads: Inspect the brake pads for wear, as low fluid might indicate that the pads are worn down and the fluid level has dropped.
4
Test Brake Pedal Feel: Press the brake pedal; it should feel firm. If it feels soft or spongy, this could indicate low fluid.
5
Scan for Warning Codes: Use an OBD-II scanner to check for any brake system-related codes if the warning light is on.

Solution

1. Preparation

Gather tools needed: funnel and clean cloth.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear gloves and safety glasses to protect against brake fluid.

2. Locate the Brake Fluid Reservoir

Open the hood of the vehicle.
Identify the brake fluid reservoir, which is typically found near the back of the engine bay on the driver's side.

3. Inspect and Clean the Reservoir

Wipe the outside of the brake fluid reservoir with a clean cloth to prevent contamination.
Check the fluid level; it should be between the "MIN" and "MAX" lines.

4. Add Brake Fluid

If the fluid is low, remove the reservoir cap carefully to avoid contamination.
Using a funnel, add the appropriate type of brake fluid (most likely DOT 3 or DOT 4) until it reaches the "MAX" line.
Replace the cap securely after adding fluid.

5. Test the Brake System

Start the vehicle and press the brake pedal a few times to ensure it feels firm.
Check for any leaks around the reservoir and brake lines.
