Hydroboost died in my Chevy Silverado ...
Hello,
The hydroboost in my 2000 ChevySilverado 2500 died at 46,000 miles due to broken pump shaft a few years ago. I was lucky to have been going slow on a side street, as on the truck it powers both brakes and steering, and lost both. Very dangerous set-up IMO. I had roughly 10 percent stopping power after that, if that. I left work early and drove slowly on the highway, and kept 1/8th mile between me and cars in front, and was planning on driving in to the guard rail to stop if the need came. I had no ability to panic stop and was really squeezing it on that ride home. Vacuum brakes at least stop, albeit with a harder pedal if it goes.
For the T-Type, I contacted RedRegalT, and bought his vacuum conversion. Haven't installed it yet, but not going to trust PM or hydro down the road, especially when car is getting faster. HTH.
