Looking for power brake booster & master recommendations

[The Rebel]

The issues l have are:

Some previous owner put in the purple cam which caused the engine to not generate enough vacuum to properly fill the booster for proper breaking, so l had to install an external vacuum pump.

The guy l bought it from converted the front drums to discs and the shop that did that installed a new master cylinder and a non-OEM style booster, wish I had the original parts they took off.

The booster is not an OEM style booster and l want one to get back to an OEM appearance.

Based on post #3, l now feel my breaking will be more improved with the unit posted.

What is wrong with yours?

Ok…. Looks like its a toss up between Dr Diff, and Pirate Jacks…I don’t see much difference between the 2, unless there’s some sort of discount being a forum member?

New master & booster ordered.
Seems like Dr Diff is extremely knowledgeable and helped me thru the ordering of correct parts …
Fingers crossed ill end up with none leaking great brakes!
Thanks to all for the input.

Cass is great to work with. Keep us posted on the project as I've decided to put in the right unit over the winter.

So what unit number did Dr Diff advise and you ordered?

I am looking at the inline tube stuff. I had good luck with other parts I ordered from them, so was leaning towards their set up. Seems similar to the stuff that has been posted here.

That must be what is listed in Post #3 but I was not sure if the post was saying this was the one to use or not. Thanks for the reply.

Any updates??

 

[koosh]

No updates yet, had to travel day after receiving the Dr Diff items.
A tad disappointed though, was hoping to get instructions with it since I’ve never installed these in the past.

You started this post stating your
master leaks at the line connections.
Isn't that the main focal point of
failure?
Re-tap master (even if it means
jumping up a size on the fittings).
You're dealing with parts that are
more than 50 years old and god knows
how many times those parts have
been "brought back to specs."
I would assume what system you have
is able to stop the car except for the
leaking lines.....KISS....

Not dealing with 50 year old parts….in post#1 shows brand new INCORRECT master and booster, a GM setup which original owner installed. Through research here, leaks occurred because GM master and Mopar steel lines do not mate…..keeping it simple

Out of curiosity, where is the Bendix tandem booster assembly? The master cylinder assembly looks aftermarket not the one that goes with the booster.....looks like a GM master cylinder......or is this pix unrelated....????

That is a Mopar set up. Introduced in
the '80's with Dodges' Diplomat or
Plymouths' Volare.
Pulled mine from a Dodge Diplomat
police cruiser.
The dual diaphram booster is spec'd
for a mid 80's Chrysler New Yorker.
I'm running 4-wheel disc"s.

Just throwing something out there as another option Bob…

As my car has a non bendex booster but I'm pulling the correct vacuum with the help of a vacuum pump due to the purple cam, if I changed the booster to a bendex would l see any improvement in breaking?

I have installed 2 of these on a Road Runner and a GTX they work great and look the part. Those like you have have been nothing but problematic. I have 3 of those style boosters taking up space in my garage.

What’s that linkage on the back of the booster? The reason I’m asking is that the prior owner put in a power disc brake conversion and the brake pedal is way too high. The brake light switch also is hanging up on the pedal sometimes.
