Yeah. I hate to say it but there's a LOT of people right here driving all around the country with single circuit brakes who are really "accidents looking for a place to happen"

It's just a matter of time.

 

Did you use an electric hydraulic PS pump, or regular? I assume you don't have OEM power steering in the old truck. I heard Toyota's have electric PS pumps and figured that might be a good donor. Thanks for the donor info on the hydroboost. I'll start my search in the local junk yards.

 

I was going to install a couple year newer power (assisted) steering system and I have everything including the pump. (It uses a control valve in the drag-link....I don't like that kind of power steering)

Now I think I'll just use the pump for the booster and maybe to power my liftgate. But it will operate the booster with nothing else connected.

I was particularly worried about master cyl fluid volume until I did a little measuring. The original MC has a piston diameter of 1.375" and if I remember correctly and about 1.5" piston stroke.

The newer F350 dual MC has a 1.5" diameter but a slightly shorter stroke. After a little calculation of available volume, I determined that the newer MC will have more than enough volume.

I will need a proportioning valve though to prevent excessive pressure in the front brakes with adequate pressure in the back.

Someone else used the same system in an F500 or 600 and said the brakes work extremely well.

I looked up the mid 2000 and found OEM PN: 5C322140FA is a MC for 05-07 F250-550 SD. That sounds like what you have. My 74' F650 is 1 1/2" dia. so no issues there. After market (Rock Auto) shows a hydroboost with and without "Brake control valve". Do you know if that is a check valve? Or are they idiot lights or abs feeds?

 

I am not familiar with that Brake Control Valve.

I do know that since I have dual wheel cyls (upper and lower) on the back and single piston wheel cyls in the front, the volume is different (probably less required in the front, so I'll need a proportioning valve...

 

Has anyone replace an old booster to a newer style yet? How fabrication was required? Use the old pedal system?

 

I bought a hydroboost for a Ford superduty. It is secured to a plate with an 8 point nut. I removed the plate cut the studs off and drilled the 3 hole pattern from my old master cylinder in it. Plate is too big to fit so it has to be cut down a bit as well. Bolted up with the original pedal assembly. The return line landed on the cross member. I drilled it with a hole saw and welded in a pipe to replace some of the section lost. Here's an old thread with more information. https://www.ford-trucks.com/forums/1...ster-help.html

 

Is the Wilwood 260-11179 brake booster still the best choice for a F600?
