Hydroboost problem

[Scott Norris]

Has anyone had a hydroboost syestem not circulate fluid? I bought this from Hydratech before they went dealer,just getting the car running now.Started engine,before it reached operating temp the PS fluid was 246 degrees.Started checking lines and the fluid deadheads at the Hydroboost. have tripple checked the routing.PS-hydroboost-rack-cooler-resivoir-pump.Hydroboost lp-res.I hate not being able to talk to the manufacturer.

Like Mike says, I'm always here at least twice a day. Lat-G members can always look at my profile and get in touch with me directly as a result. First, take a deep breath, relax, and know that you now have my attention - I will work with you to get your scenario straightened out right here.

99% of this type of concern stems from having the adjustable brake pedal rod set incorrectly to not allow the brake unit to acheive a full state of release when the brake is not applied. Go ahead and crack loose the brake pedal rod adjustment under the dash and back off the adjustment (lowering the brake pedal height adjustment considerably to make sure the brake unit isn't being engaged or preloaded when not in use) OR disconnect the brake pedal rod from the brake pedal entirely for diagnostic purposes. If the PS system comes to life and all is now well, then we all chuckle about how adjustable items are infinitely more troublesome than non adjustable items.

I have a few questions: What model number brake assist system? What type of vehicle? 1st gen Camaro? Or? What type of PS pump? What type of steering gear? The more you can tell me about your specifics, the more accurate I can be within the diagnostic discussion. In cases like this, I also like to advise that a complete bypass of the hydraulic brake assist unit be performed, as the problem may not be related to the hydroboost unit at all. You can either take the two high pressure lines loose of the brake unit and then play some fitting games to interconnect them, or the high pressure hose from the PS pump to the brake assist unit can sometimes reach the steering gear as an easier bypass solution. As stated in the very first part of the system installation instructions, the power steering system must be in 100% condition to operate the hydraulic brake assist properly, so let's make sure the PS is functioning.

Let us know what you find and we'll take it from there.

I have an idea, but since Paul is here, its just my 1/2 a cent.

Check the return line. Where is it returning? Is it tee-ed into the line correctly. I have found that any resistance in the return will cause a problem. Just from my experience, but Paul is the king, so I'll wander off now.

HB #3021 67 camaro March Ultra w/Type 2 pump, Sn95 rack, DSE res, cooler,#6 AN thruout exept the low pressure return from res it is #10 AN.Will disconnect brake pedal and bypass both tomorrow.And no Gregg,when you have pressure going in one side unhook the line from the other and nothing comes out thats pretty much deadheading.

Ok,Here is what I did today.Reinstalled HB unit but left it loose on firewall,DID NOT hook it to brake pedal,Installed lines,turned pump by hand it comes up to compression-bleedoff.Installed belt deadhead at HB.Reroute line and bypass HB to just steering rack can turn by hand and watch fluid circulate back into res.Install belt work fine with just steering hooked up.Now what?
