⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety glasses and gloves when handling brake fluid, as it can damage paint and irritate skin.
•Ensure the vehicle is secure and on a flat surface before performing any maintenance.

Symptoms

•Brake warning light illuminated on the dashboard
•Soft or spongy brake pedal feel
•Decreased braking performance or responsiveness
•Visual inspection reveals low brake fluid level in the reservoir
•Brake fluid appears dark or contaminated

Diagnostic Steps

1
Check Brake Fluid Level: Open the hood and locate the brake fluid reservoir; visually inspect the fluid level against the 'MIN' and 'MAX' marks.
2
Inspect Brake Fluid Condition: Remove the cap from the reservoir and check the color and clarity of the brake fluid; it should be clear or light yellow.
3
Look for Leaks: Inspect hoses, lines, and brake components for any signs of fluid leaks.
4
Test Brake Pedal Feel: Press the brake pedal; if it feels soft or goes to the floor, this may indicate low fluid or air in the brake lines.
5
Check for Warning Codes: Use an OBD-II scanner to check for any diagnostic trouble codes related to the braking system.

Solution

1. Preparation

Tools Required: Safety glasses, gloves, brake fluid (DOT 3 or DOT 4 as specified in the owner's manual), clean rags.
Ensure the vehicle is parked on a level surface and the engine is off. Allow the engine to cool if it has just been running.

2. Check and Top Up Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Clean the area around the reservoir cap with a clean rag to prevent contamination.
3. Remove the reservoir cap carefully.
4. If the fluid is below the "MIN" mark, use a funnel to add new brake fluid up to the "MAX" mark.
5. Replace the reservoir cap securely and wipe off any spilled fluid.

3. Bleed the Brakes (if necessary)

Sub-steps:
1. If you suspect air in the brake lines, gather a brake bleeder kit.
2. Start with the brake furthest from the master cylinder (usually the rear passenger side).
3. Attach a clear hose to the bleeder valve and place the other end in a container to catch fluid.
4. Have an assistant pump the brake pedal several times and hold it down.
5. Open the bleeder valve to let fluid and air escape, then close it before your assistant releases the brake pedal.
6. Repeat until no air bubbles are visible in the fluid coming out.
7. Top up the brake fluid in the reservoir as needed during the process.
