Tip & How-To about Ford F-150
Required tools and supplies:
Box-end wrench suitable for your car's bleeder screws.
(An offset head design usually works best)
Extra brake fluid (about 1 pint if you are just bleeding)
(3 if you are completely replacing the fluid)
12-inch long section of clear plastic tubing (sized to fit snugly over your car's bleeder screws)
Disposable bottle for waste fluid.
One assistant (to pump the brake pedal).
1. Open the hood and check the level of the brake fluid reservoir.
2.Add fluid as necessary to ensure that the level is at the MAX marking of the reservoir.
3.Do not let the reservoir become empty at any time during the bleeding process.
4. Begin at the corner furthest from the driver and proceed in order toward the driver.
(Right rear, left rear, right front, left front.)
This will also allow the system to be bled in such a way as to minimize the amount of potential
cross-contamination between the new and old fluid.
5. Locate the bleeder screw at the rear of the caliper body (or drum brake wheel cylinder.) (Remove the rubber cap from the bleeder screw)
6. Place the box-end wrench over the bleeder screw. An offset wrench works best since it allows the most room for movement.
7. Place one end of the clear plastic hose over the nipple of the bleeder screw.
8. Place the other end of the hose into the disposable bottle.
9. Place the bottle for waste fluid on top of the caliper body or drum assembly.
(Hold the bottle with one hand and grasp the wrench with the other hand)
10. Instruct the assistant to "apply." The assistant should pump the brake pedal three times,
hold the pedal down firmly, and respond with "applied." Instruct the assistant not to release
the brakes until told to do so.
11. Loosen the bleeder screw with a brief ¼ turn to release fluid into the waste line.
The screw only needs to be open for one second or less. (The brake pedal will "fall" to the floor
as the bleeder screw is opened. Instruct the assistant in advance not to release the brakes
until instructed to do so.)
12. Close the bleeder screw by tightening it gently.
13. Instruct the assistant to "release" the brakes. Note: do NOT release the brake pedal while
the bleeder screw is open, as this will **** air back into the system!
14. The assistant should respond with "released."
15. Inspect the fluid within the waste line for air bubbles.
16. Continue the bleeding process until air bubbles are no longer present.
Be sure to check the brake fluid level in the reservoir after bleeding each wheel!
Add fluid as necessary to keep the level at the MAX marking. (Typically, one repeats
this process 5-10 times per wheel when doing a ‘standard' bleed.)
17. Move systematically toward the driver – right rear, left rear, right front, left front -
repeating the bleeding process at each corner. Be sure to keep a watchful eye on the brake
fluid reservior and Keep it full
18. When all four corners have been bled, spray with brake cleaner and wipe dry with a clean rag.
Try to avoid spraying the brake cleaner DIRECTLY on any parts made of rubber or plastic, as the cleaner
can make these parts brittle.
19. Test the brake pedal for a firm feel.
(Be sure to inspect the bleeder screws and other fittings for signs of leakage. Correct as necessary.)
