I think www.vdubcustoms.com has a kit with N/A brakes. I'm sure Lanner would be happy to adapt some turbo calipers to his kit for you.

PM or email Pillow. he is only on here occasionally. he did a 944NA conversion on his split and is pretty well versed in the options.

Porsche brakes on a T2

I looked into doing this when I had a Bay window Westy.
To fit up front is not bad, you need to space the bearings 10mm further apart (at a 5mm spacer behind the inner and outer bearings) and then the hub will fit onto your T2 spindle. They use the same bearings.
Then you need to make up a pair of caliper adaptors and off you go!... well its never quite that easy

At the back, its a lot more difficult. There is nothing in common with Porsche stuff. I was going to look at drilling the hub for Porsche studs, slipping the Porsche disk over the top and then make up a plate which bolts to the rear arm and accepts the Porsche backing plate... but I never got that far so don't know if any of that will work.

Good luck.

Been doing alot of research with a couple of friends into porsche discs on the rear of a bay, we think we're close to a workable solution and it's suprisingly straight forward!

Remove original a-arm mounts and replace with bug items with modified profile to suit bus torsion tube. The position of these will have to be measured carefully from a bug/porsche.

Modify bus springplates using porsche springplates as template to take 944 a-arms and disc assembly.

Bolt everything up... hand brake mech. will need some work, cable manufacturer should be able to knock something up.

The only bit i've not resolved, is whether the bus master cylinder can still be used or a 944 one can be fitted without too much modification.

I'm open to comments/thoughts etc...

nb. these ideas are based around using an early 944 rear setup.

ps. - Mike... Hope you're enjoying Oxford

The biggest problem is the Hand/Emergency parking brake,
Here in the UK you HAVE to have a cable operated emergency brake to pass the M.O.T. (road worthyness test) and this is what most people fint difficult to overcome, the best way around this it would seem is to use alloy 944 rear trailing arms (easy on a splitty as you have to start from sctrach to install IRS anyway) but just howmany people have done this on a bay???????
I wouldn't even know where to start to maintain the correct geometry

I think the alloy arms may be too wide for a bay as they add at least an inch to the track width each side [from memory] you may get away with it as you have a late bay with more space in the arches at the back... with my early bay, there's very little space between the arch lip and the tyre [195/60's on 7" 52mm offset 'dials] 22mm of that is the wheel adaptor, but the early 944 setup will increase the track by a bit too so space will be limited!

Handbrake cables: easy! Get speedy cables to make some up for you... from what i understand thay are very acommodating, you just need to give them all the measurements!

How are you two guys getting on with your brake conversions?

I have just made the 2 5mm spacers and inserted them behind the bearing seats. Whne tightened up there is still play, as if the bearings are loose. It appears that the spacers need to be a bit bigger then 5mm, I am going to check today, so will beable to report back.

On another note how compatable are the 4 pot brembo calipers with the vented disks from the sigle sliding caliper, there looks like a fair amount of difference between the thickness of the two disks.

Cheers

John

Unhappy

Hi John,

Things have hit a brick wall as far as my brake conversion goes
I got stitched up by customs with a £250:00 bill when my brakes arrived from the US
I'm still trying to figure out what to do at the rear end,
I think I may either put the complete rear end from a 944 or just the spring plates & hub assembly (this will probably be the way I will go) if I can find the correct size, the other thing that is causing me difficulties is I want to use wheel bolts as opposed to studs so it will give me that extra inch or so, making it slightly easier to fit the rear wheels which means I am going to have to get 996 rear hubs!!
Heres a pic of my brakes

sorry about the size
