How To Remove Brake Fluid Reservoir From Master Cylinder

If you ever take a close look at your vehicle’s brake, you will find a reservoir. This tank is made with plastic, and its task is to feed brake fluid to the master cylinder. In case there are cracks or other deformations in this component, or it gets damaged. This step will help you to escape the threats of contamination or fluid leaks. In such situations, it becomes inevitable to detach the master cylinder for examination and, consequently, replace the unit if the situation demands it. It would help if you did this by positioning the cylinder in a fixed spot so that no damages are caused to the brake fluid tank. 

Why Does The Brake Fluid Reservoir Need To Be Changed?

Our automobile may have many problems that need to be resolved, one of which may be the brake fluid reservoir. This is a problem that requires attention and timely resolution in order to be solved before a catastrophic car accident occurs.

Any damage or breakage in this area of the car can lead to spills of oil or other substances. If the fluid spills and spreads, you may have to deal with some contamination in the vehicle. If you check before things get out of control, cleanup will be a useless and time-consuming task.

How to Remove Brake Fluid Reservoir from Master Cylinder

For those who are familiar with automobiles and their parts, all of these experiences will not be too onerous. All of this is the point, and you’ll be done with it soon enough.

However, this may not be true for everyone, especially those who have never done anything like this before.

Therefore, to help you, we provide information on what you should do to get the job done without ruining it or hurting yourself.

Items Needed For Removal:

  • A screwdriver with a flat head or a pry bar
  • A vise

Step 1: Raise The Car Hood

Before starting work, you must first check the problem area. In this case, the problem lies in the engine compartment located under the front cover of the car.

Before proceeding, be careful to secure the car hood in place, as it could collapse and injure your head or neck. To prevent it from falling off, there is a pole.

Step 2: Find Master Cylinder

An automobile engine is a complicated mechanism. For those unfamiliar with this project, it can be difficult to determine what is behind the hood. Therefore, you must first find the master cylinder before continuing with the disassembly procedure.

Depending on whether one side is on the driver’s side, you will place it on the right or left. The plastic or metal components will be located near the firewall. You will see that four brake hoses and lines are connected.

Step 3: Secure with a Vise

You can start working after finding the master tank. For this, you must fix and tighten the master cylinder body. The vise must be clamped so that you can work on the cylinder. If you do not have this, your task will be difficult.

Step 4: Insert Screwdriver Or Pry Bar

After adjusting and securing all parts, insert a pry bar or flat-blade screwdriver between the metal or plastic cylinder and the brake fluid. Just make sure that the tools you use are of high quality so as not to damage anything else.

Step 5: Push Off the Reservoir

Now that you have inserted the screwdriver between the reservoir and the cylinder, you must press it in some way to completely remove the reservoir from the cylinder.

Once finished, you must remove the rubber that connects the two. You are ready!


Now, if you know what needs to be done to complete the job, this task will be easy. All you need is a little help and guidance, that’s our purpose here!
