CB performance Roto-Hubs, and Varga calipers a-la Pontiac Fiero. Whole kit was reasonably priced, and I like it. Bolts right on as-is, but I had to drill for, and install longer studs and spacers for some 17x9 Cup 3's.

On the 1303 I'm building for myself, I'll use '84 944 stuff on all four corners, including the rear control arms, and some 951 spring plates.

I plan on using the stock M/C on my 1303 too, just for simplicity's sake.

Hmm, see im not to sure on using the stock M/C, Michael ghia was saying it wont push enough volume to feed the 944 brakes, you would end up with a long pedal stroke and maybe hit the bulkhead.

I can concur with a long-ish pedal stroke. The brakes are applied within 1.75" of pedal travel using a stock M/C.

A smaller M/C bore will provide more mechanical advantage, making the brakes apply tighter, but at the sacrifice of having to push the apply piston farther for the same reaction.

The half inch or so difference in pedal stroke didn't seem worth the hassle of plumbing for brake light switches, and retrofitting a Porsche M/C on her Bug.

Just a little info I thought I would share. The 911 master cylinder I have has the same bolt spacing as the bug M/C and it has the pressure switches in the M/C just like the beetles. It also has brake hoses coming from the top of the M/C to go to a remote resevoir just like the beetle. The only real modification that I will have to do is either thread the bolt holes in the M/C or use a nut and bolt to attach it to the pan and shorten the push rod. :)

That would be a better and safer retrofit than a 944 M/C.

Thanks for the tip Brendan! :)

I'll take some pics if I can get my hands on a digital camera. :laugh:

that's good info genius. a little late, but good. :D

tapping for the switch on the 944 m/c wasn't too big of a deal, but i was already re-running lines. bigger deal if you aren't. there was a pic of it in the gallery, but don't see it now. should be on my computer too, but can't find it there either. i will get another pic just as info for all. (i know you know how to deal with it :) )

boygenius,
Which 911 master cylinder do you have?
-emerson

I think its a 1987 911 SC. :)

What are its cylinder bore sizes? I'm asking because I have a master cylinder that appears to be from a 911 (like you describe). Its cylinder bore sizes are 23(23.81mm?) and 14(14.29mm?). If I apply Shad's brake bias ratio calculation to this master cylinder using 944 N/A calipers, I get .81045:1. I don't think this ratio is what I would want. Compare this to using the 944 master cylinder with 944 N/A calipers, yielding a ratio of 1.43577:1.

Don't know. When I bought it it was said to be in working order so I'm going to use it as is. If I have a problem when I go to bleed the brakes in a few weeks and I have to rebuild it I will let you know. If it ain't broke don't fix it. :laugh:

See my updated previous post with updated calculations.

For sure let us know how the 911 master/C works....

The 944 servo will not fit within the Super's body/pan. I'm not sure about the Standard Bug but I think the 911 servo will fit their cars.

Mike was saying the super had MORE room, im not to familiar with servos.
dont they mount "remote" from the M/C anyways? if they do i could stick it any where i wanted in the trunk couldent I?
And is it correct that all you need to run the servo is a vacume source (such as from the intake maifolds)?
