Title: 4 stud Front-disk Rear-drum to 5 stud disk/disk conversion...
Post by: billabong on 09 April 2013, 12:08
Hi Folks,
I have a GTI that i'll be scrapping soon, I also have a 1.9D (1Y) that is 4 stud with rear drums.
I want to convert to 5 stud so was thinking I could use the setup from the GTI?
What would be needed?
Will I need to mess about with the master cyclinder?
Taa

You could just swap the rear beam over with everything attatched not to sure about the master and braking bias side of things

Your diesel might have smaller master cylinder (most likely will have).....

Swapped all the components on the diesel to 288mm front and standard rear disc setup from a vr6. Only problem that you will face is the rear bias valve if your diesel doesn't have abs. You can leave the rear beam on the car and swap over all of the hubs and calipers etc but may need brake lines made up from the bias valve. Mine was completely corroded and not working anyway so i just scrapped it and left the tdi master cylinder on. I will warn you that it does lock the rears if i massively stand on the brakes in the wet, but for day to day driving its fine. The swap itself isnt that hard as the whole front hub/lower arm/driveshaft from the gti fits straight on, 2 bolts on the lower arm, 2 bolts on the hub and 6 spline bolts on the driveshaft, then obviously the brake lines.

If it does have abs i still would think it would be a problem unless it runs the same abs pump but im sure its programmed with rear drums on the back and would fail to run a disc braking system im sure it would lock up alot more

Dont the driveshafts on the 1.9D have 90mm flanges and the GTI 100mm?
