Does anyone have any experience with a replacement brake booster.
I have a '69 and I would like to continue using my original MC. Tuff Stuff makes a new, USA made, replacement , but the push rod is sized for their own MC. Per their tech guy, it probably won't work with original MC's. They do make a combo booster/mc that would be a good fit, but the MC doesn't look original--no bleeder screws.
Any other new made brands available?
I'm hesitant to get a rebuilt unit because of the general crap that is out there.
Thoughts??
Looks like a good place, but, I'm not sure the one I have is original. I don't see any numbers on it and the exterior looks better than other parts around it. China junk????
This Stainless Steel Brakes, new, US made looks good. https://www.paragoncorvette.com/p-35...e-booster.aspx
I went with the tuffstuff booster and master cylinder becasue I wanted the round style booster to fit my hydraulic clutch bracket ( it still needed alot of modding)

I looked at the TuffStuff and it looks like a good option. But, per their own tech advisor, their master cylinder is not a direct replacement for a GM Delco unit. If you ever have a problem, you'd have to rebuild theirs or buy a new one from them. Seems that the push rod on the booster is not adjustable and only the right length for their mc.
So, I could not use my original mc which has the distinctive bleeder screws.

Yes they do use a precision cut rod. I measured it and it was perfect. Those CSSBinc ones I linked too look good, I think they are all made in theUSA. The paragon one looks like CSSBinc as well. CSSBINC also sells the masters with the bleed screws.

I have the Tuff Stuff booster and used my oem master cylinder. The oem adjustment rod wasn't used with the TS booster. The adjustment for the TS MC rod is done at the rear of the booster with adjusting nuts on the brake pedal connection. Been stopping the car for years now with that setup.

Thatsa different adjustment and is pedal to stop adjustment. The pin inside is booster plunger pin to master plunger cylinder. Anytime you use two different or unmatched brake master and booster you should measure to make sure the pin is correct. I have a tool like this which makes it supper simple. Prior to that i used a caliper and straight edge. If you dont have the adjustable pin you can use a solid rod adn just measure it to the correct length like TS does with their matched sets

Sounds like their rod is close enough, but probably not optimal. THEIR tech advisor advised against it.

This tool comes with the booster I ordered. It should make the adjustment easier.
It's funny that the TS master cylinder rebuild kit comes with a adapter (more or less a 3/8"x1 1/2" rod) to use with deep hole master cylinders.

Its a great tool, I have giant one for cutches too.....always gotta buy a new tool. Theres not much to those rods. The adjustable ones are pretty nice to have but once you get the size you dont need it to be adjustable anymore...
In general, would prefer a quality rebuilt booster over one w/ aftermarket shells from ?
crap shells/crap assembly nicks diaphragms which prematurely tear then leak.

THEIR tech advisor doesn't know his product or TS has changed their design. I can assure you that my TS booster mated with my oem MC without issue. The adjustments are made at the brake pedal connection.

The key word here is "quality".
I'm sure that there are some good rebuilders out there. But, overall, because of the age and condition of core's, china parts, etc., rebuilt usually doesn't equal new factory built.
The unit I bought is USA made by Stainless Steel Brakes Inc. in Florida. Very good reputation. The other new unit I found is a generic replacement made in china. I would seek out a good rebuilt over the china one.
My experience from buying master cylinders, ps pumps, ps slave cylinders, alternators, carbs, etc.

You're probably right. Coupled with the instructions provided by Rogers, it could work.
Are the adjustable rods on all or some units? The factory product pictures that I saw didn't show them. The rod spacer that would be needed for a '69 deep hole mc is not provided with their booster only. I did see it pictured with their mc rebuild kit, but it is not available separately. Their tech said he had heard of people making their own spacers but I'm not going to mouse in brake parts.
Anyway, I looked at them, almost bought, called them, then decided not to buy.
They seem to be a good American co. Hopefully they can clear up any misinformation out there.
Or, if you're so happy with them, perhaps you could give them a heads up?

They changed their design. My booster doesn't look like anything in their pdf's and I'm using the oem MC, not theirs. Again, my rod adjustment is done at the brake pedal and not at the MC. My booster was also '76 C3 specific and not a universal one.
I said C3 specific but maybe not. However, that's the booster that's selected for my year vette from their website. And it works.
