  • Check the brakes while taking a small drive and make sure that the problem is with brakes.
  • Secure the vehicle on flat surface and put it on parking brake.
  • Prop the engine hood up and look for the master cylinder reservoir on the driver side.
  • Withdraw the old brake fluid out from the reservoir and add fresh brake fluid to the reservoir.
  • Next, loosen the wheel lug nuts before using floor jack.

  • Remove the bleeder screw and let the old fluid and air bubbles withdraw through the piece of tubing. Recap the screw.

  • Fill up the reservoir with new fluid as required. Make sure that the level of the fluid in the reservoir is touching the ‘Max’ mark.
  • You have to repeat the steps from 9 to 14 for other remaining wheels you have to follow the order like left rear wheel, right front wheel and then left front wheel.
  • Put the wheels back and secure them with lug nuts. Remove the vehicle from jack stands and ground the vehicle.
