Rear sierra brakes/hubs
iiyama - 22/4/07 at 06:46 PM

Think Im probably breaking new ground here so not sure Ill get an answer.

I have push in shafts from a drum braked car. However I didnt want to use the brackets that mount the callipers, ie the plate of steel. So I have sourced some standard sierra bearing carriers from a disc braked car and made the smaller bearings to fit by getting some sleeves made for them. All well and good so far, http://s114.photobucket.com/albums/n251/vm1451/?action=view&current=DSC00491-1.jpg


However Ive just mounted up one disc and the caliper dosent fit even though its a standard fitment, (although not a sierra caliper). It looks like I need to space the caliper of the mounting by around 8-10mm. Dont really want to do that. So....

What if I get the backof the hub machined off and maybe 2-3mm of the face where the wheel will sit? This will effectively move the disc back into the center of the caliper. I also realise it will change the rear track slightly.

Anyone see any problems with this? Other then the fact Im making life difficult for myself??

i think you need to get the rear disc hubs too, as these are prob shorter than the drum ones ( the drum ones need to be deeper to compensate for the depth of the drum, where as the disc hub needs to be 11mm shorter, as the disc mounts on the front of the hub.

i might be able to help you out on the hubs next week.

also, are you sure you bolted the caliper bracket to the right side of the hub carrier?

i thought spacing callipers out was commonplace?

you could have just used these on you're standard drum bearing carriers with no probs or hassle. Rescued attachment Sierra brake bracket.jpg

Re the last post, yup! I know I could have had two of those, but I like to be different!

Pretty sure they are bolted to the right side of the mounting. They are on the disc side, if on the other side the offset would be a lot worse!

Re the first post I have the disc hubs. Check the link and youll see. Unless I've misunderstood you of course!

fair do's - i have never seen a drum style hub before, so i guessed it was the drum hub as you did not say you had brought the disc hub as well as the carrier.

perhaps the drive shafts are too long...

if you want to go the whole rear disc route, i will be putting a whole rear disc setup ( DIF, drive shafts, hubs etc ) up for sale next week if your interested. u2u me if you are. would save you a load of hassle.

Thanks bud, but the idea was to keep the weight down, hence using push in shafts. However to be honest by using the disc hubs which are heavier and then shimming the bearings Im not sure Ive saved any wieght at all!

Anyway Ive started down the road so Ill see the journey to the end and see what happens.

As you say, by using either a carrier plate with drum hubs, or using a disc set up the it would have saved a load of hassle, but to be honest I didnt realise when I started what a work up it was going to be!

The drum bearing carriers are very similar to the disc version, except they are slightly smaller and of course have no lugs for calipers.

Actually, having read that again, you are of course talking about the hubs! I am indeed using drum hubs, not disc. Never occured to me that they might be different!
