- Seals your brake master cylinder reservoir
- Helps protect brake fluid from moisture and debris
- Replace when broken or missing
Your Nissan's braking system includes a brake master cylinder that contains the brake fluid. This reservoir might be responsible for holding the fluid, but your Nissan Brake Master Cylinder Reservoir Cap helps protect the fluid from contaminants and stop it from splashing out or leaking.
Most brake fluids take in moisture from the air. This moisture can lower your brake fluid's boiling point and negatively impact the performance of your brakes. Your Brake Master Cylinder Reservoir Cap helps keep the moisture away and make your brake fluid last longer. While you might be tempted to drive without a Brake Master Cylinder Reservoir Cap, it's not recommended for this reason.
If there's a problem with your Brake Master Cylinder Reservoir Cap, you might not know until it's too late. To help make certain the cap is in position and working correctly, it's a good idea to visually inspect it occasionally. You should check for cracks and make certain it's sealing the reservoir effectively. After a brake fluid change or brake maintenance service, you should verify that the mechanic remembered to replace the cap correctly.
If your Brake Master Cylinder Reservoir Cap is broken or missing, a replacement is needed. Without it, you risk contaminants and moisture entering your brake fluid and potentially leading to brake failure. The cap is easy to replace on your own — simply twist it onto the reservoir. Still, you may want to take your Nissan into the nearest service center to have your brake fluid's moisture level checked, especially if you're not sure how long your reservoir has been exposed to the elements. Typically, your brake fluid should have no more than 3% water.
