Step-by-Step Procedure for Changing Brake Fluid in the CRV
Changing the brake fluid involves carefully flushing out old fluid and replacing it with fresh fluid while ensuring no air enters the braking system. The following outlines the methodical steps to perform this maintenance.
- Begin by parking the CRV on a level surface and engaging the parking brake.
- Open the hood and locate the brake fluid reservoir. Clean the reservoir cap area to prevent dirt contamination.
- Use a turkey baster or fluid extractor to remove as much old fluid as possible from the reservoir.
- Refill the reservoir with fresh brake fluid to the “MAX” fill line.
- Identify the brake bleeder valves on each wheel. The typical sequence for bleeding is:
- Right rear wheel
- Left rear wheel
- Right front wheel
- Left front wheel
- Attach a clear tube to the bleeder valve and place the other end in a catch container.
- Have an assistant press the brake pedal slowly several times, then hold the pedal down.
- Loosen the bleeder valve slightly to allow fluid and air bubbles to escape through the tube.
- Tighten the bleeder valve before your assistant releases the brake pedal.
- Repeat this process until only clear, bubble-free fluid emerges.
- Monitor the brake fluid reservoir and keep it filled to prevent air from entering the system.
