Boosters and Master Cylinders

[Glenn 'Stinky' Stankevicius]

I have currently got a LC/LJ Torana booster and Master Cylinder fitted up to the FE Sedan, the problem is a slow persistant fluid leak from the Master Cylinder.
To date I have not been able to pinpoint where the leak is coming from, only that the rear reservior loses fluid.
In anticipation of taking it to a brake shop, are there any other booster/master combos that I might want to look at instead, that will fit where the Torana gear currently is?

Stinky, the Torana master cylinder is 1 inch bore as are all the H model Holdens and Commodores, so any master cylinder will be OK on your car.  Differences occur with the thread sizes on the pipes as well as the later Commodore masters having built in proportioning valves.
I would suggest getting a new Torana master cylinder the same as what you have got and you will fix the problem for good, rather than trying more second habd ones.

A couple of months later ...........

I took the FE for a pre-Rego inspection drive today with a few hard braking stop thrown in. Once stopped I got out of the car and started looking around the master cylinder for the leak.
It seems to be coming from a small bolt in the bottom of the master cylinder.
Only the rear resevoir is losing fluid, would this be the case if that bolt is leaking?
What sort of washer should be used? Fibre or metal?

Hard to say without looking at the problem/photo but I'd probably fit a copper washer if the bolt is the leak problem.You could try fibre but copper is more durable.

After getting a new Master, I had the old empty one sitting on the bench for a while. The problem end up being a casting fault with brake fluid seaping from a small hole in the casting.
