Fixing a leak with your brake fluid can be done by any mechanically inclined do-it-yourselfer. If you have never done repairs on your car before, you will need to first sit down and review the information about your car. It is a good idea to go to your local automotive parts store and ask if they have diagrams regarding the braking system and how it works. Do not attempt to fix the lines or the fluid leak if you have not done your proper homework. Once you have reviewed material and spoken to different people, you can use the following directions as your guide to fixing any leaks.

Know Your Limits

First and foremost, you must know your limits. If you do not understand the components to your car, or if you are not intimately familiar with brake fluid and the requirements thereof, you must first either spend some time familiarizing yourself with these sections of the car or pull out your user manual and spend time studying. You should know that fixing the brake fluid leaks in a car is not done with a quick, easy solution. Many companies promote a quick-fix brake fluid formula and it has been proven time and time again that these formulas do not help.

Master Cylinder

Check your master cylinder. If it is showing signs of wear and tear or even leaking, you will need to go to your automotive parts store and purchase a rebuild kit. Pull the directions out of the rebuild kit and follow them closely. They will direct and show you how to take off a master cylinder and add a new one.

Brake Hoses

Take a look at the brake hoses to assess any damage. If they are leaking, you will need to purchase a set of new ones. Then, simply replace the old hoses.

Brake Lines

If it is only the brake lines showing signs of leaking, you can easily fix the leak with metal tubing and pipe bender. Purchase the necessary parts at your local store, and then pull out your user manual for your car and walk through it step by step to effectively fix your brake fluid lines. This is not a simple task. Enlist the help of a friend or someone that is in the know when it comes to automobiles. If you cannot find the proper help and you’re not confident in your own abilities, it is time to pay for a mechanic.


Purchase a new caliper at the automotive parts store and follow the directions inserted with it. Use these along with any pertinent information contained in your manual. Again, if you are unsure, do not change the new calipers. It can harm your car.
