- 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 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 stop it from splashing out or leaking.
Most brake fluids absorb moisture from the air. If enough moisture is absorbed, it can lower the boiling point of your brake fluid and make your brakes less effective. Your Brake Master Cylinder Reservoir Cap helps keep the moisture away 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 a problem with your Brake Master Cylinder Reservoir Cap, you might not realize it until it's too late. To help ensure the cap is in place and working right, you want to visually inspect it every once in a while. You should look for cracks and make sure it's sealing the reservoir effectively. After brake maintenance services or a brake fluid change, you should double-check that your technician didn't forget to replace the cap.
When your Brake Master Cylinder Reservoir Cap is damaged or missing, you need to replace it. Without it, you chance contaminants and moisture entering your brake fluid and possibly leading to brake failure. It's easy to replace the cap on your own — simply screw it onto the reservoir. However, you may want to bring your Nissan into the nearest service center to have your brake fluid's moisture level checked, especially if you don't know how long your reservoir has been left unprotected. Usually, your brake fluid should have no more than 3% water.
