Default Rear Discs

I raised a thread a long time ago which discussed the the disc brake arrangement. This has however subsequently been deleted; but for the benefit of any new forum members I will raise a new one.

It basically says: Don't make the rear uprights to the book spec!!!! I have spent the last 5 hours milling and boring out the old welds from RU7 & RU8 plate!

Hope this saves someone the headache of what Dad and I went through today!



Before

That's looking a much better angle for the rear calipers Nick

I bet you had great fun seperating that plate from the upright .... Not

What exactly is wrong with the book design? Are we talking about the 1st revision orientation issue, or another issue?

Caliper hits the shock mount.

This is what we eventually levered off after milling of all the weld.....



The second revision book specification is still wrong for this item, or at least it is for a standard sierra brake caliper!

They just need fitting and a few holes of harness. Then its all comfort and cosmetic work

Arrgh!

I wish I'd seen this earlier as I have a set of rear uprights made to book spec, and until today I hadn't thought to offer up the caliper. Looking at it one option could be to swap the assembly to the other side. The bleed nipple would end up at the bottom, but apart from that it looks like it could work.

Did you try that? If you did were there other problems?

Matt

I tried it in almost every position I could think off! The main issue is that the calliper cannot run freely in any position without either the handbrake cable or the brake pipe fowling on the lower wishbone.

I am not sure how you will modify it if you do not have the correct tools, it took dad and I 4 hours and that was using a Pro 3000 Mill MX2 mill. Hope you find a way to get round it.
