Posted: Fri Feb 13, 2009 4:54 pm Post subject: My DIY rear disc brakes (step by step pics) |
|
|
Finally got the rears done.
I used calipers and vented rotors from an 91 Audi V8. These are found on a lot of early 90's Audi's with vented rotors.
The hubs are turned down and the stud holes were drilled 1mm larger for my NAPA longer studs there shoulder is 1mm larger than the stock vanagon studs. The studs hold the rotor centered.
Since I already have 15" alloys with the right ET, I didn't want to put a big spacer under the rotor.
It turned out good except I had to put five 1/16 washers, 1 on each stud to push the rotor out a little. I think with a little grinding on the bracket it will work without the washers.
The brake hose are bug lines from cip1.com. They are 10mm bubble flare, male on one end and female on the other. I ordered six 480mm lines. It took two lines per side on the rear and the other two lines are for the front.
Thanks to all the other post for all the great info and pushing me to finally do this.

I didn't do anything with the ebrake, mine is rusted solid. That's a project for another day.
It took three different designs before I found out this was the only way I could do it without a big spacer between the rotor and hub. So there was a lot of time into these, but now it wouldn't take 1/4 the time.
It's probably around a $100 for a pair.
Thanks Jeff _________________ --------------------------------------------------------

Looks good! You should be able to modify the e-brake cables to work with those calipers when the time comes.
FWIW, the vented 10.6" rear discs were only used on 1991 Audi 200 quattro 20Vs, 1990-1994 Audi V8s, 1992-1995 Audi S4/S6. The 5000 quattros, earlier 200 quattros, and C4 body 100 quattros all used smaller diameter non-vented rotors.

Any chance that you would be able to provide a material list and drawing of your brackets? _________________ -cliff

What rear Wheel studs did you use?
Do I HAVE to pay $8ea for 944 wheel studs for these rear disc setups?
I will be using some Audi alloy rims that do require longer stud setup.

I'll get the part # tomorrow.
They are Pretty cheap $2 or $3.
The knurl is 1mm larger than the stock lugs so you need to drill the hub.
It works out good because the larger knurl makes the Audi rotor center itself on the studs so you don't have to make a hub centric spacer.

Here is pics of the studs.
You can see the knurled shoulder sticks out of the hub to center the rotor.

Does anyone have any idea on these conversion wheel studs?
or wouold you think the vanagon camper would just be far too heavy to take the risk?

knurl 15.72(1mm larger than the stock ones)

Hey man, that's quite OK.. and congrats.. and thanks.
the Audi 200 quattro (3B) rear rotos won't work with the subie calipers I have so I need to source some Eurovan rotors, but I am going to check the Syncro front rotors for a rear spot 1st.. if they are the right thickness and of course bolt pattern I may use those.
but will still need good studs to hold it all together.

JROBEWESTY, I did a little more internet digging on these so heres some more info.
The part# you listed is for a 99-97 Cadillac according to DORMAN wheel bolt catalog
but when I went to www.napaonline.com and tried ALL of the combinations of 97-99 Cadillacs they all are listed as 12mm x1.5 wheel studs. Isn't the vanagon 14mm?
