Welcome to the new look VWWatercooled

After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.

Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

The new forum software is an upgraded version of what came before, it's mostly the same but also a little different. Hopefully easier to use and more stable than before. We are learning together here, so please be patient. If you have questions, please post them here. If you have worked something out and can provide an answer,

  • More brake and suspension Photos

    I'm just about to put white back together again after cooking the brakes at Sandown, just thought I'd share a few photos.

    New Ball joints.

    The originals are riveted in and have to be drilled out. The holes in the new ball joint are an odd diameter so I tapped them for a M8 x 1.25 thread and set them up like this.




    Here's the knuckles with new bearings installed. One of the hubs had to be replaced because the bearing shaft was galled. The other Hub had the holding screw snapped off so that had to be drilled and tapped.




    Assorted brakes bits, MK3 rear callipers, The notorious GTI (Or is it Audi?) callipers both with new TRW pads which are supposed to be good for 650degrees.

    GTI vented front discs. I'll clean that paint off the braking surface before I put them on.

    New braided lines. I had the rears made in a single length to save a few dollars on fittings and to simplify things a bit. (There would have been two hoses and a solid section per side otherwise.)



    I also went to the bolt bar to get some replacement bolts but I had to upgrade to socket heads because they only had 8.8 s in the hex heads and the originals were 10.9. The socket heads are 12.0 which can't be a bad thing. ( If you didn't understand that last bit the numbers refer to the tensile strength of the bolt the bigger the number the stronger it is along it's length.)



    There's still a few more goodies on the way before I'm done. I'm looking forward to seeing how all this works out.

    Next track date is in April. Hopefully I'll get the car sorted by then and take it out to Phillip Island for some instruction.

      if it werent gay, i'd say i love you pete. nice work

      why'd you go with socket head bolts for the balljoint-control arm connection? just curious.

      how does the car stop with the big rear brakes? i've got the SEAT rear drum setup with gti rotors/calipers on the front and that seems to balance out well.... with my current setup. i couldnt imagine i'd need anymore stopping power on the back than the big drums... since they scrabble for traction already, even with my stiff shocks. one advantage i've noted with the big drums is the good bite they have with the handbrake.....

      anyway, just curious.

        one question for you how much bigger
        are the gti brakes compared to standard?
        my wheels only just clear standard ones
        but i wouldn't mind something better

            Overkill The balljoints are riveted in originally so there's no way to know what torque or clamping pressure is required. The socket head screws have a high tensile strength, higher than the equivalent hex head that the bolt bloke stocked.

            All the other brake and suspension bolts had a 10.9 rating, but the store didn't stock 10.9s in hex head, only 8.8s, so I went with the socket heads throughout which are rated at 12.0.

            Stronger = better!

            Weaker = Dangerous!

              ahh.... i use high tensile in everything i replace.... in the manual it states that upon renewal of the balljoint, the rivets should be replaced with 6mm ??? bolts.... hahaha lots of info there. but honestly, its overkill anyway, they are only ever loaded in shear, and 3x6mm steel bolts in pure shear.... well you know it aint gonna break first.

                They're the same diameter 239mm just thicker - 22mm instead of 10-12mm. I have no problems with 14" MK2 Steel wheels. I have a stock 13 I could try over them to see if it clears ok if you need to know.

                I think some of the MK1 GTI s actually had 13" wheels but I'm not sure which brakes went with that.

                  Yeah I was going to use 6mm but the holes in the arm and the joints measured at 7.2mm (??!!) WTF am I supposed to do with that?

                  Didn't want any risk of slop in there so I just spun an M8 tap through them and bolted them up with the M8 Unbrakos. I reckon I'll tear the arm out of the chassis before these ball joints come off

                    I have gti brakes on mine and it cleared with the stock 13's. I think there may even be a pic of it in my thread. I'm runnig mk 3 steels now, and theres plenty of room. Highly recommended upgrade, esp if you are looking at replacing the origional brakes (due to wear age, ie regular maintainance.

                      Your right Pete, Mk1 GTi's ( Golf and Scirocco ) all came with the 239 x 22 disc and larger calipers. They clear the factory Std 13 x 5.5 alloy wheel by miles.

                      The Ball joints should come with M7 bolts and nuts ( 8.8 Mpa grade from memory ) guess it depends who your supplier is..

                      So interested in what pressure limiting valve or proportioning valve your going to run to the rear brakes ?? I see your using the 22 mil master cyl...

                      Some of the thread holes on the rear brake set up are Metric fine, your SHCS bolts pic'd there all look to be metric std pitch...just dont want ya chewing out threads..

                      Lots of MK 1 Scirocco's...

                      If it aint a MK 1 then it must be a donor car ??

                      Cheers,

                        My supplier was Matt (Loon) There were no bolts in the boxes. M7 is a pretty weird size, but the holes would be right for that.

                        Got some of the Scirocco ones from the US ( with the right numbers for discs)

                        Got it covered, I picked some up. You can see 2 of them just at the edge of the green tray, the pitch isn't obvious but they're M10 x 1.25x20 al the other M10s are 1.5 pitch. Thanks for the warning though.
