Either my vacuum pump is failing (Not likely as it's somewhat new but you never know these days) or the brake booster has failed (happens) but either way I'm not terribly interested in fixing either and would much rather switch to hydroboost. Or air brakes. As hydroboost is the far more likely and accessible of the two that's the direction I'm going to head in.
It's a 1986 F250 in amazingly good shape for a truck that old in Iowa no less! My question is there a particular year of hydroboost that I should be after or will pretty much any of them from the F450 line work? I'd be awful sad if I bought one and couldn't make it work as easy as it seems on all the threads (note: not that anything I've ever done has gone so easy but it's the thought that counts) The current master cylinder still work? (allegedly replaced recently by the PO). Current power steering pump handle it so long as I can plumb in the extra line for the return?
I'd love to be able to stop again without having to stand on the brakes.
Otherwise by way in intro my truck is in my profile, I'm still sorting out what was done to it and, so far, it looks like it was done by someone who knew what they were doing. Currently chasing all the little things that go wrong on a truck that's 30 years old. My background with the 6.9 goes waayyy back in the 1990's when I was turning wrenches for a postal contractor and he bought a Navistar truck from the Post Office and said "Make this work" Up to that point it had been LP converted Ford LS series, a couple of 3208 cats, and a pair of NTC Cummins with the odd postal jeep thrown in for flavor. I won't proclaim to be a guru and my memory is a bit fuzzy at times but I'm confident enough in my abilities to get into a lot of trouble quickly. Oddly, perhaps, prior to that I made a living fixing air cooled VW's. Currently bug free and recovering nicely, thank you, though it's very likely that I'll succumb to owning one in the not too distant future.
As the handle implies I have an affinity for the Mazda rotary as well. Guess I like engines off the beaten path right?
Thanks for the replies in advance!
