Any newer options for brake master cylinder rebuild or brake booster repair?

I was removing these two items from my engine bay this evening and as I have done with most items, tried to research what options were available for repair/upgrade/rebuild if needed. There are two options noted in the FAQ, one for www.powerbrakes.com (the link in the FAQ is broken but the website can be found) and the other for the great Hal Boyles at 2002sonly. Unfortunately the first doesn't seem to do these rebuilds anymore as they are listed as "sold out", as is Hal's site. Regarding the brake master cylinder, this also seems to be a hard part to find. I got a bit worried when I broke one of the connectors but those appear readily available. Any new sources for these two items?
Based on at least one prior thread, I emailed Jay Stratton, but unfortunately the reply I got from him was rather rude - over three emails he asked first whether I read English, second whether I'd read his website, and then send a third email stating "Are you surgeon. You do not know the terminology to be working on Cars. People like you need to google and learn terminology before you start asking questions"
Point taken. He does not repair vacuum brake boosters.

This still leaves the question of what to do if either of these parts fail. Rebuilt master brake cylinders seem available for north of $700. A thread from last year had Don noting that this part could be found from bimmerparts and others, but unfortunately everything now seems out of stock. Options?

Hi,

Also considering replacing/having rebuilt my brake booster (late 72 CSi , flat one).
Hard to find the exact ref from ATE.
Gained contact with a shop in the Netherlands, specialized in reconditionning ATE BB.
Got a proposal for 400usd (intra Europe shipping).

For the brake cylinder, was recently still avalaible by Walloth&nesch, not cheap, but secure , and wirth the two versions of the brake cylinder.
 
Booster ships to Power Brake
Tell them you want powder coated

Keep in mind, master cylinders come in 2 sizes

If anyone is looking for a new ATE Power Brake Booster/Servo I can recommend the same one used in the Porche 924/944. It is an ATE T52 with part number P/N: 94435502311.
The mounts to the body bracket and to the brake master cylinder are the same. The diameter is 9 inches (instead of 10). One difference is that the drum itself is a little shorter. There are two ways to get around this: Either cut the push rod by about 13mm and thread it up to the corresponding length or screw a nut onto each of the four mounting studs to maintain the distance to both the brake pipes and the brake rod. The price is around 300US$
It provides the same braking force as the OEM part.
 
I have a box of new rods available but sending in your own booster for rebuild is cheaper and easier.
