Understanding the problem is a failed power brake booster,
why not rebuild it? I stumbled into this problem on a TR6
and found TRF willing to sell me a new one for $200 or a
junkyard's unknown but bent one for $100. All my friends
free ones (6 units total) had been given away in the past
year to other TR6 owners.
Theory: The booster diaphram breaks after about 20 years
after brake fluid leaks
Solution: Buy a new unit for $200
Replace the diaphram $10
Okay, so order a new diaphram... NONE of the usual places sold
it, only new units (how do they build new units, used diaphrams?).
I was told it was a liability problem... (why do they sell MC rebuild
kits?, at least the booster is manually backed up)
I was told its impossible to rebuild the units.
I was told there was NO OTHER option, buy new while its still available?
So, I sent it to a brake/clutch rebuild center and for $90 received the
sandblasted/repainted/revalved unit which I am now using... AND I forgot
to tell them that the diaphram IS NOT available. I am tempted to
disassemble the unit to look at the diaphram, it likely has a GM part no.
My guess is you can order the diaphram under some universal number from
a supply house for $10 and either do it yourself or have a local place
rebuild it. It needs special tools to hold/rotate the pieces.
So, the question begs to be answered: "TRF WHY DON'T YOU SELL THIS DIAPHRAM?"
I can give you the name of a place which will rebuild it, but someone must
know the "REST OF THIS STORY" - any takers?
