Title: Porsche 944 brakes - Anyone using them? Post by: Lee.C on March 07, 2009, 11:17:39 am We've been talking about it other threads so I thought it was time for it own thread as a few people seemed interested :)
All the info I have so far comes from Mr Fastbrits (Keith Seume's) VW BEETLE PERFORAMCE HANDBOOK many of you probably have this book, it shows how to make a very simple bracket that allows you to fit the 944 front calipers it also shows how you need to "spot face" the rear of the spindle to mount the bracket, It also show just how easy it is to fit the rear discs to a beetle as well BUT it say there is NO handbrake facility :-\ So lets have your thoughts guys - Anyone used/using the 944 set up ???

Post by: Arnoud on March 07, 2009, 15:57:45 pm I've used the setup for 3 years in my 68 sedan and braking was very good.It can be done on both IRS and swing-axle rear ends.I personally didn't like the fact that it widens the rear track-width by an inch per side.

Title: Re: Porsche 944 brakes - Anyone using them? Post by: tikimadness on March 08, 2009, 21:38:55 pm I am using the 944 brakes on the back of my project.
I have the hubs copied in aluminium and the discs are being lightened and balanced right now. I won't use the 944 cailpers because of the size and weight but will be using 92-93 carrera 2 rear brake calipers. Michael Title: Re: Porsche 944 brakes - Anyone using them?

I take it the original hubs are Steel then? Title: Re: Porsche 944 brakes - Anyone using them? Post by: tikimadness on March 09, 2009, 16:49:18 pm I am using the 944 brakes on the back of my project.

Jep the original are steel.I won't be using the handbrakes on my project but I used them on my previous car.It is relatively simple to get the handbrakes to use.

Michael Thanks dude but I did just check your other thread - all very interesting :) Title: Re: Porsche 944 brakes - Anyone using them? Post by: Lee.C on March 10, 2009, 02:30:35 am One big question I do have is DO THESE BRAKES FIT OVER FUCHS ??? ??? ???
Title: Re: Porsche 944 brakes - Anyone using them? Post by: Bewitched666 on March 10, 2009, 08:04:19 am Yeps,i tested a set of fuchs and they fit 8)
Title: Re: Porsche 944 brakes - Anyone using them? Post by: eugene on March 10, 2009, 10:29:07 am I will be using 944 single pot calipers with dropped spindles and deep 6 fuchs. The dropped disk spindles need some modification to mount the caliper but it can be done. The fuchs fits but it is tight. The caliper needs a little grinding and the hydraulic cylinder housing would need to be changed from left to right in order to bleed the brakes properly but it is possible. What i don't like about the brakes is the weight.

I take it the original hubs are Steel then? I, too, am using the 944 brakes front and rear and like them a lot. The handbrake is easily hooked up and holds my crew cab well when parked. The increased track in the rear can be a problem for the beetle (I've only installed these brakes on type 2's and 3's. You will need custom length cables if one of the stock lengths will not work for your application. Look at the parts books for available lengths and then measure the car. Yes, they are heavy, but that was not an issue for me, though it is for others. You can narrrow the rear trailing arms if you are so inclined to bring the track back to stock. It's not too difficult to do. All the best. Hope this shed some light on the subject.

Post by: vw-bigblock on March 10, 2009, 23:10:02 pm I'm using 944 breaks front and back on my -66 with 3,5 inch shortend front end and 5 inch shortend rear end.
At the front i used the porsche hub and just made som small tubes and put on the spindle tap so the porsche bearings fit. Tthe breakdisc is a 303mm at the front and the calipers are Brembo Porsche aluminium calipers. I cut down the original calipermount 1,5mm and screw an 8mm "flatiron"(sorry dont know what its called) 40mm wide and around 160mm long and then screwed the calipers in them. At the back it was bolt on, just had to put 3mm of shims behind the Brembo caliper. The hand brake was the problem and i solved it by connecting the short porsche wire(needs two set of breakcables) with its shielding tube to the original vw wire under the (non excisting) backseat.

Cool thanks for the info buddy - it sounds like your using the later 944 stuff :-\ :) Title: Re: Porsche 944 brakes - Anyone using them? Post by: Tobias Bylund on March 11, 2009, 10:20:18 am I was also looking at the exact same conversion for my 1303 super that i am building for circuit racing, but the 4 piston calipers from porsche 944 are so extremely overpriced in my opinion, used 20yr old stuff shouldn´t have to cost around $400 for a pair just because it says porsche on them. So i started looking at wilwood calipers instead, and ended up buying the Powerlite calipers, radial mount 4 piston billet aluminum, takes an 11"x.86" rotor, and best of all, brand new for 300 including pads of your choice.

Post by: kafercup on March 15, 2009, 02:00:13 am I have the Porsche 944 Turbo 4-pot brakes front and rear on my 71 super with the 944 master cylinder. The modulation is great and you'll never need more braking than this in a car this light. Check this site out, it's where I got alot of my conversion hardware http://vdubengineering.com/ .
Title: Re: Porsche 944 brakes - Anyone using them? Post by: j-f on March 15, 2009, 09:18:58 am Which kind of front tires do you use?
I also have start a chassis with IRS and 924s brakes but I have change my mind because I think if I would use the classic cal look tires combo, skinny front tires just can't handle the brakes power.

I think you have a BIG HEAVY right foot dude :D ;) :) I think 155's should be fine with "single pot" calipers "4pots" my be a little OVERKILL in my eyes. My main reason for the 924s/944 setup is that DISCS can withstand LOTS of heavy braking (read as street racing ;)) even in the Manx after ALOT of hard driving the drums do get alittle SOFT :D ;) Also dude you could fit an adjustable "Bias Valve" ;) Title: Re: Porsche 944 brakes - Anyone using them?

Why not use a simplest way with stock discs and bigger callipers as Talbot horizon? Bolt on, factory looking. Type 3 drums on the rear and it should work for the use we do of our cars. Street cars, not race track use. Title: Re: Porsche 944 brakes - Anyone using them?

That is not a bad idea dude - That is the set up my friend is using on his 68 in my other thread, its a VERY good set up BUT I just like the idea of the 944 setup ;) :) |
