How To Flush Brake Fluid

How Do I Flush My Car’s Brake Fluid?

It’s important to flush brake fluid to ensure that all brake lines are devoid of fluid. This is typically done when replacing a brake master cylinder.

Here are some instructions on how to do the flush.

  • Set the parking brake
  • Open the hood and identify the brake master cylinder vessel (typically located right behind the driver’s side of the firewall)
  • Chock three of wheels to create an additional level of safety
  • Jack the vehicle up onto the furthest corner of the vehicle from the brake master cylinder (This is typically the rear right of the car, although if you have an ABS module installed, use the module as the starting point for the evolution.)
  • Once the vehicle is off the ground, install a jack stand
  • Drop the car back onto the jack stand
  • Undo the lug nuts of the wheel and remove its wheel/tire combo

Once you have access to the brake system, do this:

  • Identify the bleeder nipple
  • Place a fluid hose on the bleeder nipple
  • Using a small crescent wrench (sizes will differ depending on the car)
  • Slightly uncrack the bleeder screw
  • Slowly push the brake pedal throughout its complete cycle
  • Repeat this process until all fluid is pushed out of the particular line and into the fluid vessel or in the hose
  • Close the bleeder screw and remove the fluid vessel/hose from the brake nipple
  • Move to the next furthest brake assembly and repeat the process until all four brakes are devoid of air
  • Once no fluid is identified in any brake line, removal and replacement of the master cylinder can occur as necessary
