hydroboost problems

[vince72]

guys i need some help;
i just installed my hydroboost system. the unit is from abs power brake,
the problem that i am having is that when we attempted to bleed the rear right caliper the fluid would not come out with pressure. this is after about twenty minutes of trying. then we tried it with the car on and we got the same low pressure, and also the lines that run from the hydro to the power steering pump would get hot (is it suppost to?)
please help me

I was just on Htdratech's website and they do say that it is normall for the lines to get hot during operation as for the line pressure problem i don not know how to help. May be you might have a clog in the line on a kink in the line.

I had the same problem. Wrong master cylinder.

Is there a chance you have the line from the p/s pump to the hb and the line from the hb to the steering gear reversed?

I did that to the one on my Blazer and after looking at my El Camino a few times I finally realized I had the lines backward! I swapped them and voila, I had brakes!

thanks vince

Car on/off will have no effect on being able to bleed the system. It can and should be bled with the engine off.

The power steering feed/return lines will get warm if the engine is running.

Did you bench bleed the master cylinder?

I agree with the above. Either the wrong/bad/incorrectly bled master cylinder.

i did find out about the maser and it is one for a disc set up. since this weekend we had no success as soon as i have the chance i will bleed the system all over again. i will start from the master and then go to the furtherst most to nearest the master, wish me luck

Vince, I bought my master cylinder from Baer. It was what they sold me. It still did not work. I had the same bleeding problems. I talked to Paul at Hydratech, switched MC and 10 minutes later all is good.

Great guy. Very knowledgeable.
