Ford F-150/F-250: How To Replace Brake Fluid

Changing the brake fluid can not only increase braking power, but also protect and increase the life of other brake components. Here is how to replace the brake fluid on a Ford F-150 or Super Duty truck.

This article applies to the Ford F-150 (2004-2014) and the F-250, F-350 Super Duty (2005-2014).

Changing the brake fluid is relatively easy, inexpensive, and can prevent the headache of dealing with a shop. For those with a little helper in the house, this job makes for a great learning experience, too! A truck's braking distance highly depends on how well this job is done. Specific yet common tools are required, and it is essential to set aside adequate time to complete this task.

Materials Needed

  • 5 quarts Dot 3 brake fluid
  • Empty container (milk jug or 2 liter soda bottle works well)
  • 3/16” clear tubing to fit over brake bleeder valve
  • Wrench that fits the bleeder valve
  • 4 jack stands and a jack
  • Tire iron
  • An assistant/helper

Step 1 - Raise the vehicle

  1. Loosen the lug nuts on a wheel.
  2. Using the jack, raise the truck until a jack stand can be slid underneath the lower control arm.
  3. Remove the wheel and lower the truck onto the jack stand.
  4. Repeat for the remaining three wheels.

Step 2 - Bleed the brakes

  1. Open the hood and remove the master cylinder cap located on the driver side firewall (Figure 2).
  2. Siphon off any old brake fluid from the reservoir.
  3. Top off the brake reservoir with the new fluid.
  4. Attach the tubing to the bleeder screw on the passenger side rear brake; bleeder valve is located on the caliper on the side closest to the truck frame.
  5. Loosen the bleeder screw to let fluid drain from the tube into the container (Figure 2).
  6. Have an assistant pump the pedal until the clean, new fluid starts to come out air bubble-free (Figure 3).
  7. Promptly tighten the bleeder screw so fluid isn't wasted.
  8. Re-install bleeder screw cap if applicable.
  9. Repeat these steps for the driver side rear brake, then passenger side front brake, and driver side front brake in that order.

  • Figure 3. Bleed the brakes.
  • Figure 4. Pump the pedal.

Step 3 - Final review

  1. Re-install the tires and lower the truck back onto the ground.
  2. Make sure the reservoir is filled, and re-install the cap (Figure 5).
  3. Pump brake pedal a few times; the brakes should feel firm.
  4. If the brakes are not firm, there is a chance there is an air bubble in the brake line. In this case, bleed the brakes all over again. If not, the brakes can possibly fail with an air bubble.
  5. Properly dispose the old fluid.
  6. Re-torque lug nuts on the wheels in 50-100 miles.

Pro Tip

Dispose the brake fluid by taking it to Autozone.
