Instructions:

  • Secure your vehicle on a flat surface. It is a good idea to set on the parking brake.
  • Prop the hood up and look for the master cylinder reservoir.
  • You have to use battery filler or a turkey baster to evacuate the brake fluid from the master cylinder reservoir. Add new brake fluid to the master cylinder reservoir and make certain that the new fluid fulfills the OE specifications, i.e. DOT3 or DOT4.
  • Raise the vehicle with floor jack and it is better to secure it with jack stands so that you can work underneath the vehicle without any fear.
  • Take block of wood and put it under the brake pedal to make certain that it doesn’t move.
  • Starting from the right rear wheel, look for the brake bleeder valve. You may find it connected to the brake caliper or brake wheel cylinder.
  • Fix a piece of clear plastic tubing on bleeder screw and insert the other end of the tubing into the container filled with brake fluid.
  • Instruct your assistant to depress and release the brake quickly for sometime and then hold it in the depressed position.
  • Remove the bleeder valve and let the old fluid and air bubbles evacuate. Once the air bubbles stops coming out, recap the bleeder valve and told your assistant to release the brake pedal.
  • During this process, make sure that the fluid doesn’t flow out completely. Add more brake fluid to the master cylinder and make sure that it reaches up to the required mark.
  • Bleed the remaining wheels’ brakes by following the same process. You need to move on to the left rear wheel, then to right front wheel and finally the left front wheel.
  • In the end make sure that brake pedal has enough resistance.
  • Remove the jack stands and floor jack and ground the vehicle.

Tips & Warning

  • Use safety clothing like safety goggles, latex gloves, and closed toe shoes to prevent injuries during the repair work.
