Rebuilt brake booster

DIY is fine..and something I've done for decades. I've got more stories of 'professional' screwups than you have the time to listen to...things along the line of an NHRA record holding machine shop that made me a custom set of pistons that raised the heads 3/8" off the block deck.

When the cost of the parts equals or exceeds the cost of someone else doing it...why bother with it? For no good reason I figured...so I didn't.

A Midland kit for my car is the same as the cost for someone else to fuss with the entire mess....someone that has been doing the fussing for many years.

Nope. Not much inside of a booster. Also, not at all worth my time (and I have a LOT of it) according to me to deal with it.

YMMV of course.
