944 N/A brakes to 1303 questions (yet another)

[yetibone]

I put 944 calipers on the front of <---that car. I used the stock M/C with NO problem whatsoever.

I don't think power brakes are nessecary. The car could weigh anywhere from 1700 to 2200 lbs. With Brake calipers and rotors designed to haul down a 2700 lb car, pedal effort would still be on par with, or less than a 944 equiped with power brakes. Non assisted brakes have a better feel IMO.

SuperVW,
If you are using 944 rear brakes, will you be using 944 trailing arms?

I dont plain on using the arms, just the brakes.

So what are you using for the rear, as it sounds like your only using the fronts from a 944?

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.

[yetibone]

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.

[yetibone]

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

Thanks for the tip Brendan!

boygenius,
Which 911 master cylinder do you have?
