Driving with low brake fluid can be very damaging to your car's brakes. Seeing as it is quite easy to check your brake fluid, and to fill it if needed, it is worth learning how to refill your own brake fluid.

Difficulty: Easy
Instructions

Things You'll Need:

  • Brake Fluid
  • Funnel

    How to Refill Brake Fluid

  1. Step 1

    Pop the hood on your car open. Most cars have a lever on the inside of the driver's side door that will release the hood. You can then feel underneath and find the release. Once you push up on that your hood will lift.

  2. Step 2

    Prop your hood. There should be a bar attached at the front of the hood that you can swing up and put into place, holding your hood open so you can work. Others will stay open automatically.

  3. Step 3

    Locate the brake master cylinder. It should be on the driver's side, toward the back of the engine compartment. The cap will most likely read "use only DOT 3 or 4 brake fluid from a sealed container."

  4. Step 4

    Open the cap and see how much brake fluid is already in the car. There will be a full line, and the brake fluid should reach this line.

  5. Step 5

    Place a funnel in the brake fluid tank and begin pouring in brake fluid, making sure to keep your eye on how much you are adding. Fill to full line.

  6. Step 6

    Once you have filled the tank with brake fluid, recap it. Replace the bar and close your hood.

Tips & Warnings
  • Do not overfill the brake fluid container. There should be an indication as to where the brake fluid should come to.
  • Make sure to keep brake fluid away from the reach of young children, as it is harmful if swallowed.

on 7/26/2009 BALONEY! Brake fluid level decreases as brake pads wear. The fluid is still there, it has moved down to the calipers to compensate for the reduced thickness of the brake pads. When new pads are installed, the reservoir will overflow if you have added fluid. When your fluid reservoir nears the MIN level mark, it is time to have your pads replaced. The only exception would be if your brake system has developed a leak.
