      I have just the straight up syncro, I'm assuming to switch to disc brakes that it's probably just a matter of swapping on some form of factory bracket to hold the caliper and also the hub and rotor. Is this right?

      Edit....

      I need to clarify this thread. I understand how to do a rear disk brake conversion on any other car. I also figured out that the G60 syncro had them too. What I basically need to know is does the hub somehow attach directly to the control arm or is there another bracket that bolts on first.

      Check out this site gives you an idea what is involved. http://www.amh-tuning.de/index1.htm
      The rear hub gets pressed in just like the front and all you do is bolt on the caliper carrier and caliper. Hope this is what your looking for.

      Is this pressed into the bearing....because that's kinda what it looks like to me.

      Looks to be pressed into the hub should have the ears on the back side with the threaded holes for the caliper carrier.

      Well that's the problem I'm having

      Here you can see I have the control arm sitting in my room. Those holes you see that look like they could be for a caliper, they aren't threaded. Then you can see that splined sleeve the axle goes into, so does the hub press onto this or what.....That's my problem. Do I need that piece from a disk break syncro because the drum one won't accept the hub from the disk setup, or do I just need to get the hub from a syncro setup.

      Or did VW in their wisdom (which they're admittedly very good at usually) design the system so that you can use the disk brake from ANY rear disk setup and just press it over that sleave to accept the axle (I.E. is that sleeve the same as a VW rear stub axle in outer dimensions just with a hole in it so it can accept the axle)

      Okay first off the splined part is the hub, it is pressed into the control arm with a bearing. The holes should not be threaded as the caliper carriers have the threads ( carriers are syncro specific) in them. The rotor goes on just like the front of the car with a set screw to hold it to the hub. Hope this helps.

      So are you telling me the drum setup and the disk setup use the same hub....because that's what I'm asking.

      Looks to be the same but I've never seen the hubs for drum brakes in person, I can't imagine they're different. You need to see if someone can check etka to compare part numbers.

      NO!
      Drum rear ends use a spindle shaft. The Drum spins on the bearings between the shaft and the drum its-self, which the wheel bolts too.
      If you are running a CV jointed drive shaft, the outer cv joint will fit through the hub-via splines, and drive the wheel.

      OK that answers that question but the picture of his still looks like a regular disc brake rearend, am I right or wrong?

      yes it does, but he needs to pull off the drum and show us the other side

      HAHA if I could pull off the drum and look at the other side I wouldn't even be having to ask this question...I already shipped it back to the states. Doesn't anybody have an etka or something

      The answers can be found in the forums of the UK syncro site http://www.vwsyncro.co.uk, just look through the thread titles and you'll find it. you will have to register to view some of the threads. The thread on this subject can be found here: http://www.vwsyncro.co.uk/data...D=119


      To make it short, the Drum brake syncro set-up is easily converted to Discs by removing the drum and back plate & fitting the disc brake dust shield and disc. The caliper bracket mounts to the holes shown in your photos. YES the drum brake set-up uses the same hub as the disc brake set-up. you will obviously also require handbrake cables for a golf/jetta syncro, but fortunately the calipers are common Mk2/Mk3 items. Even the Mk4 aluminum calipers can be made to fit with a bit of tweaking.

      To toss another option out there:

      I had caliper carrier spacer brackets machined which bolt to the syncro control arms to allow corrado/mk3 vr front hubs, corrado/mk3 280x22 vented rotors and TTQ/R32 rear calipers/carriers to bolt right up. I will be picking up my rear syncro beam this week from being modified so I can finally assemble and take some photos of this.

      The other option is the syncro specific caliper carriers with that super wide mounting pattern.

      There's another option also, apparently the Seat Cupra-R uses 305 mm x 28 mm rotors and also the boxter caliper can be mounted up using an S3 caliper bracket....(although I only saw it done in the front)

      The width of the mounting bolts on the syncro control arms is much wider than anything else VAG. That is the issue.

      meh...oh well, I start going to school for machining in 2 months....I'm a master certified mechanic already and not looking to change jobs, I'm just looking to be able to end all this nonsense....It goes into cad in the first semester...Soon it should just be does it fit? No not yet but it will tomorrow
