Rear upright assembly
 
Aaaarrrggghhhh!!!!!

Trying to find out how to assemble my rear hubs/uprights and finding nadda!

I've got a set of off-verticle rear uprights (compatible with both drum and disc) and rear hubs off a disc-braked sierra.

My question is this: How should the uprights be alligned (leaning forwards or backwards?) and where should the caliper mountings be pointing on the hub once attatched?

I've spent an hour searching through posts and using the search fuction and found almost nought! Did find one brief post saying that the uprights should lean back on a drum brake system, but thats it!

Am I being dense? Not looking in the right place? Any help to aleviate my frustration would be greatly appreciated!

Im glad you've asked :D

Put the uprights side by side and hope I've supplied you two that are pair, ie they face away from each! The caliper goes at 10:30 if seen from the drivers/off side and at 2:30 when seen from the passenger/near side.

Bought so many parts at the same time I completely forgot I bought the uprights direct from the manufacturer!

Just had a quick look Talon (yes, they are a pair!), I take it that means the calipers are towards the rear and up, requiring the top of the uprights are closer to the front.

That sound about right?

That would depend when you start the job and if you stop for lunch or dinner.

I thought it was simply the old 48hr clock? At least that's how long any "simple" job seems to take...

Oscar,
I have the same uprights as you, but with drum brakes. I guess for disc brakes, they should be the other way around.
For drums : the two top holes of RU8 are towards the front of the car if it makes sense. On this picture: the left side of my chassis (driver side for me but passenger side for you :) )

Hope this will help.

I'm thinking, what effect would such orientation have when bleeding the cylinders? A pocket of air against the piston might be a nightmare to get out.

Now I'm even more confused! :confused:

Two top holes towards the front is how i'd guessed the uprights would be for discs. Need someone who's built a disc rear with these. Maybe Talon will be able set this to rest...
