Hydro-boost issues Q?
I've had quite a few trucks with hydro-boost and never had any issues before. I'm not a professional mechanic and have no understanding of the inner workings through experience. That time is now!
The issue is,sometimes I have nothing...pedal goes to the floor! I let the pedal return and I may get pedal or I have to give a couple/few tries. The rest of the time the pedal is low. I put a known to be good master cyl from one of my trucks and that made no difference. My instincts tell me there are internal seals that must be bad. It seems worse in cold temps and mostly when I first start it up. What do the guys with such wisdom think? And,what would be my best way to go...repair or replace? I have no idea about parts cost,how complex,reliable it would be to repair or if special tools are necessary. Don't have the Helm book ('85 6.2 truck) or GM parts book,so no exploded views. It appears to be pretty simple though. Could someone educate me?
