Dieseljunky2 : Hello, have a look at the calipers again. Are the bleeder screws on both sides on the top or bottom of the caliper? Let me know. Thanks
Dieseljunky2 : Does this truck have 4 wheel or rear only abs?
Dieseljunky2 : Ok, from your description, the booster is working correctly. Try this, put the park brake fully on, and see if the pedal changes when the engine is running. Let me know. Thanks Customer:
It didn't change. I've got the abs control module out of it right now, I don't know if that would make any difference. I also read on the internet last night that there is a procedure to bleed the brakes and i did it in the wrong order.
Dieseljunky2 : How did you do it?
I started at the ABS hydraulic unit and went to the rear and then the front. The procedure said RR then LR and then the ABS unit. Next you do the RF and then the LF, but when I break the bleeders I have good flow with no bubbles or air so I didn't see where it would make any difference how you bleed it.
Dieseljunky2 : You will need to push at least a small bottle of brake fluid through the rear and the same through the front. Here are the exact procedures from the manual. If you don't run that much fluid through it, there can still be air in the lines.
Dieseljunky2 : em.NOTE: Bleed the primary and secondary hydraulic brake systems separately.^ Bleed one brake cylinder at a time. ^ Start the bleeding at the RH rear wheel cylinder and then at the LH rear wheel cylinder. After completing, proceed to the bleeder valve on the anti-lock brake control module. Then proceed to bleed the front brakes, starting with the right front brake, and finish bleeding on the left front brake. ^ Keep the brake master cylinder reservoir filled with the specified Ford High Performance DOT 3 Brake Fluid C6AZ-19542-AA or equivalent DOT 3 fluid meeting Ford specification ESA-M6C25-A. Never use brake fluid that has been drained from the system.If there is reason to believe air has entered the brake master cylinder, bleed as follows: 1. On the brake master cylinder reservoir, loosen the master cylinder to hydraulic line fittings. 2. Wrap a shop cloth around the tubing below the fitting to absorb escaping brake fluid. 3. Push the brake pedal down slowly to the floor of the cab. This will force air trapped in the brake master cylinder to escape at the fitting. 4. Hold the brake pedal down and tighten the fitting. Release the brake pedal. Do not release the brake pedal until the fitting is tightened or air will re-enter the brake master cylinder. 5. Repeat this procedure until air ceases to escape at the fitting. 6. Place a box wrench on the RH wheel cylinder bleeder screw. Attach a rubber drain tube to the wheel cylinder bleeder screw making sure the end of the tube fits snugly around the wheel 7. Submerge the free end of the tube in a container partially filled with clean brake fluid. Loosen the wheel cylinder bleeder screw approximately three-quarters of a turn. 8. Slowly push the brake pedal all the way down. Close the wheel cylinder bleeder screw, and return the brake pedal to the fully-released position. Repeat this operation until air bubbles no longer appear at the submerged end of the bleeder tube. 9. When the fluid is completely free of air bubbles, close the wheel cylinder bleeder screw and remove the bleeder tube. 10.Repeat this procedure at the LH rear wheel cylinder. Refill the brake master cylinder reservoir as needed. 11.Place a box wrench on the bleeder fitting on the anti-lock brake control module. Attach a rubber drain tube to the bleeder fitting making sure the end of the tube fits snugly around the bleeder fitting.CAUTION: Do not reuse brake fluid that has been bled from the system.12.Submerge the free end of the tube in a container partially filled with clean brake fluid. Loosen the bleeder fitting approximately three-quarters of a turn. 13.Slowly press the brake pedal all the way down. Close the bleeder fitting, and return the brake pedal to the fully released position. Repeat this operation until air bubbles no longer appear at the submerged end of the bleeder tube. 14.When the fluid is completely free of air bubbles close the bleeder fitting and remove the bleeder tube. 15.Bleed the front brakes starting with the right front brake and then the left front brake as described in Steps 6-10 of this procedure. 16.When the bleeding operation is complete, fill the brake master cylinder reservoir to the maximum level line.
That was my next step. All I can figure is there is still air in the lines, so even with the ABS control unit unplugged I should still have good brakes just no ABS right?
Dieseljunky2 : That is correct, the abs defaults to standard brakes.
I'll try the procedure you gave me and will let you know what happens.
Dieseljunky2 : Ok
Do I need the truck running while i do the procedure or does it matter?
