Got a sweet relined #92 (7") valve body at the ready and a couple more at the machinist. Also just finished and tested a 7" MK2B unit; a bit more reliable than the MK2A critters. Send PM, etc.

Do TR6's not have the booster on the fronts only?

Back in the day I rebuilt my own servo......
My Healey has just eaten its second servo, so it is currently by-passed and going to be changed to dual circuit

I have now decided to go with dual circuit MC on the Tiger, and size the hydraulics appropriately, using a proportioning valve on the rear. A bit of math involved to get the leg force reasonable, but there are on-line calculators to help figure it out

My application has rear discs using larger Lincoln callipers on 10.4" Mustang Cobra rotors to match the Wilwood fronts, so not applicable to all.
The hydraulic sizing exercise is common to all applications

I intend to write an article on how I did the rear brake mod and the logic behind sizing the hydraulics

What was the name of that special restorer of hydraulics. Found it.. http://whitepost.com/
I have more 7" in storage but can't get to any fun project's or be a helpful hoarder.
I've seen several requests for these items lately across Tiger postings on different boards. It'd be a top vote I bet for a poll.
" What stopped the Tiger in it's tracks?"

You know what made the car undriveable and get parked then the dust collector then the first few boxes transforms to car into a garage shelf.

One of our directors had one fail on his way to meeting..

Robert the logic you mentioned is clear.
What's the warranty on a rebuild ? The same as a new clutch slave...
Not to hijack but I've been meaning to get a couple re sleeved too.

Warren: Apple Hydraulics does a fair job of re-lining in brass and smoothing the air horn seats. We use him when we are backed up. The downside is they DO NOT bevel the power valve bore and the lip seal will flip when installed, making it useless. We have to bevel it as a matter of assembly (not easy). There also was a guy in Sierra, CA but now retired. rw
