- Seals your brake master cylinder reservoir
- Helps protect brake fluid from moisture and debris
- Replace when broken or missing
Your Nissan has a brake master cylinder, which holds the brake fluid. The reservoir might hold the fluid, but your Nissan Brake Master Cylinder Reservoir Cap helps protect the fluid from contaminants and prevent it from leaking or splashing out.
Most brake fluids soak up moisture from the air. This moisture can lower the boiling point of your brake fluid and make your brakes less effective. The Brake Master Cylinder Reservoir Cap helps keep this moisture out and prolong the life of your brake fluid. While you might be tempted to drive without a Brake Master Cylinder Reservoir Cap, it's advised against for this reason.
If there's an issue with your Brake Master Cylinder Reservoir Cap, you might not realize it until it's too late. To help ensure the cap is in position and working correctly, it's a good idea to visually inspect it occasionally. Keep an eye out for cracks and make sure it's sealing the reservoir effectively. After brake maintenance services or a brake fluid change, you should confirm that your mechanic remembered to replace the cap correctly.
If your is broken or missing, you need to replace it. Without it, you risk moisture and contaminants entering your brake fluid and potentially causing brake failure. It's easy to replace the cap on your own — simply tighten it onto the reservoir. Still, you may want to bring your Nissan into the nearest service center to have the moisture in your brake fluid checked, especially if you're not sure how long your reservoir has been vulnerable to the elements. Normally, your brake fluid should have no more than 3% water.
