⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface and properly secured with wheel chocks.
•Wear gloves and safety goggles.
•Keep brake fluid away from painted surfaces as it can cause damage.
•Do not mix different types of brake fluid, as it can affect performance.

Symptoms

•Brake warning light illuminated on the dashboard
•Spongy or soft brake pedal feel
•Reduced braking performance
•Brake fluid appears discolored or contaminated
•Presence of moisture in the brake fluid reservoir

Diagnostic Steps

1
Inspect the brake fluid level in the reservoir; it should be between the 'MIN' and 'MAX' lines.
2
Check the color of the brake fluid; it should be clear or light amber; dark or cloudy fluid indicates contamination.
3
Perform a moisture content test using a brake fluid tester; a reading of 3% or more moisture indicates the need for a change.
4
Check the age of the brake fluid based on the vehicle maintenance schedule; typically every 2 years is recommended.
5
Look for any leaks in the brake lines or around the brake components.

Solution

1. Preparation

Gather tools and materials needed for the fluid change.
Tools Required: Brake fluid tester, brake bleeder kit, wrench set, funnel, clean rags.
Safety Warnings: Ensure the vehicle is on a flat surface and properly secured with wheel chocks. Wear gloves and safety goggles.

2. Remove Old Brake Fluid

Open the hood and locate the brake fluid reservoir.
Use a turkey baster or suction tool to remove the old brake fluid from the reservoir.
Dispose of the old fluid properly according to local regulations.

3. Clean and Refill

Clean the reservoir with a clean rag to remove any residue.
Fill the reservoir with the recommended brake fluid type (usually DOT 3 or DOT 4 for Honda CR-V).
Avoid overfilling; keep the fluid level between the "MIN" and "MAX" lines.

4. Bleed the Brake System (if necessary)

If air was introduced into the system, bleed the brakes using a brake bleeder kit.
Start from the wheel farthest from the master cylinder (usually the rear passenger side) and work towards the nearest wheel.
Open the bleeder screw, have an assistant press the brake pedal, and close the screw before the pedal is released.
Repeat until fluid runs clear and free of bubbles.

5. Final Check

Ensure all brake fluid caps are securely closed.
Start the vehicle and check the brake warning light; it should not be illuminated.
Test the brake pedal feel to ensure firmness.
