WRX Disk Brake Converson Brumby Photos Request.

Brumby_ProjectX · Post by **Brumby_ProjectX** » Thu Mar 20, 2014 9:28 pm

I have been searching high an low for some photos for a disk brake conversion for the brumby. Its a 92 if that helps any. Can find heaps of stuff to read but not in a lot of detail an plenty of hear say or my mate... I specifically am after the rear end to see how people are mounting the caliper an related gear. any pictures of the front would be helpful too.. I am aiming for a full 5 stud wrx setup all round in prep for an ej swap. even if some one could point me to a thread that would be great, like i said heaps to read but photos are scarce. And while I'm grasping at straws maybe a photo of the ej gearbox crossmember people are making too?
Stay classy.
Thanks, G

I just machined down the rear brake drum to use as a hub to fit the disc and redrilled it. Check out my albums for pics.

nice, I could spin that up on the lathe at work, how did you go mounting the caliper?

Long time ago but I'm pretty sure I just cut the centre out of the Back plate assembly for the the drum and welded it too the disc back plate that holds the centre on a Rexy one.

Have both back plates side by side and it will make sense

Perhaps a better way exists, I'm curious how Toongas PM said how to do it!?

Nope pretty much the same, except it was in a kit form made by a company that cannot be named here *********

(rather harry potter esque

)

By the way there would be a big market just for that part you have machined there Willy

most of the images for those who don't want to scroll through the album

Did you make the centre to fit as a seperate part?

Why why can't the company be named here? BYB competitor? I always thought that I could have a big market and for that reason never published these pics until now. Centre was shrink fitted in using liquid nitrogen. I am currently working on 1.4.2.3 firing order Camshaft just for a different note lol.

I think I asked why the name is censored I don't think I got an answer.

MMMMMMM ... liquid nitrogen ... MMMMMMM

... I just tried to picture that firing order ... Yes that will be different

Should give an interesting note combined with an unequal length header on an EA81.

Wow much easier than I imagined.
Somebody should get onto this and manufacture them. Not like there is a shortage of rear drums.

Manufacture of the rear hubs is the reason I didnt bother try to fabricate my own crossebread kit.

Willy, gotta say hats off to you mate! That's one very neat looking 5 stud hub!

And it's made from something that is often laying around doing nothing, I might have a set of dead rear drums if the rear ones on Redback check out as too thin.

I think the trick here would be to get the backing plate done right and this should be easily engineerable. The x-bread unit was almost ADR'd but didn't get there due to the required funding. If it were ADR'd I believe it would have been a bolt on kit without the need to engineer it.

Could this be done to the front hubs as well if you didn't want to go with drilling the top mount on the MY vehicles (and running a custom shaft)?

To me, this keeps the idea of the ********* kit alive, without being an x-**** kit. I believe the last run of the x-****** kits have been done, but I've not heard this from the horse's mouth.

Cheers

I have some hubs in the process of getting setup for MY or L series models. They are different to the xbread kits but use a lot of Liberty/Impreza/Forester parts. More will come to light soon.

I played around with machining down the drums but the centre piece was too thin in my opinion.

Tried this today, turns out the rotay table on the mill is stuffed, bored the pcd according to the disk and the table lost 1.5 mm per revolution D: first hub binned going to give it another crack at some point next week or so..

What WF has done looks plenty thick in the centre piece by those pics earlier.

Yeah plenty of meat, never had an issue. This went into one of my L series Royales running RS Liberty running gear and thrashed the $#! ¥ out of it and off road without a problem. One thing to remember is the centre is just to locate the rim, once the nuts are done up it couldn't move anyway. I never thought about getting it ADR approved, I just drove it.

You wouldn't do it for one vehicle - you'd only look at that if you were to go into producing a kit. With the ADR spec you'd be able to add more to the price as you wouldn't be required to engineer the kit once it's on the vehicle...
