Can You Flush the Brake Fluid Reservoir

Brake fluid is a vital part of your car’s system and as such, it’s important to make sure that you always have enough of it on hand. However, if you don’t flushes the brake fluid reservoir on a regular basis, the fluid can start to build up and cause problems. In this article, we’ll tell you how to flush the brake fluid reservoir and keep your car running smoothly.

What is the Brake Fluid Reservoir?

The brake fluid reservoir is a container that holds the brake fluid. The brake fluid helps to stop the car by reducing friction between the brakes and the wheels. The brake fluid reservoir is usually located under the car in the rear. When it needs to be replaced, it is usually easy to do yourself.

How to Replace the Brake Fluid Reservoir

If your car has a brake fluid reservoir, it’s important to keep it filled with the correct fluid level. Replacing the reservoir can be done in a few minutes, and will save you time and money in the long run. Here’s how:

1. Park your car on a level surface. Parachute or tow your car if necessary so that it doesn’t move while you work.

2. Remove the Drain Screw at the front of the reservoir with an Allen wrench.

3. There are typically two screws holding the reservoir cover in place: remove these screws with a Phillips screwdriver. Once they’re out, pop the cover off of the reservoir.

4. Locate the brake fluid pressure relief valve (it looks like a small black cap) and unscrew it with a Phillips screwdriver. The valve should now be free to move around. If it’s hard to unscrew, try using a crescent wrench instead.

5. Fill up the new brake fluid reservoir with fresh brake fluid and install the pressure relief valve, replacing any screws that were removed in step 3. Replace the cover and tighten all of the screws that were removed in step 2. 6. Drive your car, making sure to apply the brakes gradually at first and then harder as you get used to the new fluid level.

When to Replace the Brake Fluid Reservoir

The brake fluid reservoir is a small, metal container that stores the brake fluid. It contains a glycol solution that helps to stop the car. Over time, the glycol solution can become contaminated with dirt and other substances. When this happens, it can cause the brakes to stop working correctly. If you notice that the brake fluid reservoirs are starting to look dirty, it’s time to replace them.


It’s always a good idea to check the fluid levels in your brake reservoir, just to make sure there is enough fluid for the day. If you notice that the fluid level is low, you can flush it by opening the cap and pouring any remaining fluid into the carburetor. Be sure to replace the cap once you’re done flushing, so that no water gets inside and causes a leak.
