What is a brake fluid flush?

A brake fluid flush is an essential maintenance procedure on any vehicle. Brake fluid is a type of lubricant that helps to reduce the friction between the brake pads and the rotors. Over time, brake fluid can become contaminated with dirt, dust, and other debris. A brake fluid flush clears out all of the debris and restores the brake fluid to its original condition.

Why is a brake fluid flush necessary?

Brake fluid is a vital part of your car’s braking system. When the brake pedal is pressed, the brake fluid sends a signal to the car’s brakes, telling them to stop. Over time, brake fluid can become contaminated with dirt, dust, and other debris. A brake fluid flush removes all of this debris from the system and ensures that your car’s brakes function properly.

How to do a brake fluid flush

If your brake fluid is low, a brake fluid flush may be necessary. Here’s how to do it:

1. Park your car in a safe location with the emergency brake on.

2. Remove the air cleaner housing. It’s located on the right side of the engine near the firewall.

3. Remove the two bolts that hold down the reservoir below the air cleaner housing. The reservoir will now be accessible.

4. Pour out the old brake fluid and replace it with new brake fluid. Be sure to add enough new fluid to cover the metal lines running through the reservoir. Make sure there are no bubbles in the new fluid.

5. Replace the reservoir and bolts and reattach the air cleaner housing. Reinstall the emergency brake if you removed it in step 2.
