Hard Brake Pedal but No Brakes!! Help!

Well finally got the truck back and I have a few issues the one thats plauging me the most (besides not having a proper tune, some mounting of parts issues, (Insert complaint list) is the brakes my brake pedal is hard as a rock but it doesn't have any stopping power but the thing is my power steering and hydraulic assist are working fine? I don't understand! I need some help please! We've (me and all my me*****s) tried bleeding the brakes and the power steering system and nothing works. The best I got was a "contamination issue" from Ford from Elite "I should go buy the in line filter from ford to correct the problem......." I didn't have any problems with the brakes prior to my trip.

Any help that anyone can give me would be greatly appericated.

If you have a 6.4 I know nothing about it.. but sounds like a vacumm pump from a 6.0....

Given your write up I'd have to assume you have a hydromax system, which I haven't seen on Fords yet.. thank god.

Yeah, I just read another thread and they said they have an 07 with a 6.4 so I figured that was the case. We still have 09's with the 6.0 so I'm not up to speed since that motor doesn't fit in the E's :/

This is the only TSB... the only thing of interest is the possibility of crossed lines.

BRAKE PEDAL KICKBACK OR GRABBING

FORD:
1997-2007 E-Series
1999-2008 F-Super Duty
2000-2005 Excursion

This article supersedes TSB 99-25-8 to update the vehicle model years.

ISSUE
Some 1999-2008 F-Super Duty, 2000-2005 Excursion, and 1997-2007 E-Series vehicles equipped with Hyrdo-Boost(R) brake booster system may exhibit a brake pedal kickback and/or grabbing condition when applying the brakes. This may be caused by contamination within the power steering system.

ACTION
Filter the power steering fluid by installing a temporary filter in the power steering system. Refer to the Service Procedure below.

SERVICE PROCEDURE

1. Verify that the line from the pump and the line to the gear at the Hydro-Boost(R) are in their correct orientation (and not crossed). The passenger side goes to the pump, the driver side goes to the gear.

2. Attach a pinch-off clamp to the lower power steering hose approximately 6" (15 cm) from the lower port of the power steering cooler to keep fluid from emptying out of the system when the hose is disconnected.

3. Disconnect the power steering hose from the lower port on the cooler. Cap the cooler port to minimize fluid leakage and immediately install the temporary filter in line with the power steering hose using hose clamps to retain the filter (the filter needs to go in the low pressure line that goes from gear to cooler to reservoir, where it would be most accessible).

4. Attach the other end of the filter to the cooler using the clamps provided.

5. Remove the pinch-off clamp from the power steering hose.


FILTERING PROCEDURE

CAUTION BE SURE THAT THE PARKING BRAKE IS APPLIED DURING THE FOLLOWING STEPS 1-7.

1. Check power steering fluid level before starting the vehicle.

2. Start the vehicle and allow it to idle for approximately 15 seconds.

NOTE DO NOT HOLD THE STEERING AT LOCK FOR MORE THAN 5 SECONDS.

3. Turn steering wheel lock-to-lock 10 times.

4. Pump service brake pedal hard to floor 25 times.

5. Turn steering wheel lock-to-lock 5 times.

6. Remove the filter and reconnect the power steering line to the cooler. Discard the filter. Fill the power steering system. Refer to Workshop Manual (WSM), Section 211-00 Power Steering System Filling.

7. With the engine at idle, gradually apply the brake pedal until fully applied. If the brake pedal kickback persists, replace the Hydro-Boost(R) brake booster. Refer to WSM, Section 206-07.
