Brake Fitting Help Please

Postby neels on Thu 13/May/10 8:30pm

So I've finally got around to getting some brakes for my half built marin commuter bike, tidy looking pair of deore hydraulics (who says vorb classifieds don't work).

Am I correct in assuming that they bolt straight on to the mounting lugs on the rear of the frame? When initally bolted up the caliper was rubbing on the disc, by eyeball it looked like the mount was bent compared to the rest of the dropout so I gave it a tweak until it looked about right, now it looks to be running OK and has about the same clearance on the disc top and bottom.

I'm also tossing up which fork to use, I've mounted the caliper on the rockshox judy that's sitting on the bench & I'm once again assuming it just bolts straight on as it looks OK. The other option I have is manitou axel that came with the frame which has post mounts, is it just an off the shelf adapter to make the caliper work on that fork?

Apologies for the novel, and my profound ignorance of things brake related.

Do you have the older model deore brakes with the "international standard" mounts on them?
See diagram for the forks:

You could get an adapter to make the manitou's fit, called a post to IS +20 adapter
but you would also have to go up to the next rotor size (180mm instead of 160mm)

Are you using an adaptor when mounting on the Judy?
I didn't know Deore came in IS mount.
If there's an adaptor, remove it and it'll mount straight onto post mount of the Manitou.

(all assuming you want to run a 160mm rotor)

older deore brakes did come in IS mount (BR M555 as I recall, has its own odd ball pad too)

Old deore did come IS mount (around 2004), possibly earlier
pre M535 series brakes

Crap, just realised I've posted this in classifieds, damned kids interrupting when I'm half way through something :blush:

This is the calipers mounted on the frame and the judy, I can run it like that if I need to was just wondering if I could leave the axel on the frame and get an adapter to suit.

Youcan buy an adapter

either a 170mm adapter from Shimano (will need a special 170mm shimano rotor)
a Hope "plus 20" adapter (so you will need a 180mm rotor)
or a generic adapter similar to the hope plus 20

Cheers guys, looks like it will be easier to go with the judy, the brakes came with a pair of 160mm rotors. I'm trying to chuck this thing together out of what's already in the garage, the only bit that was missing was brakes as it's a disc only frame.

I'll chuck the axel up in the roof from whence it came until a use for it comes along, I don't think I really need an adjustable travel shock for biking 20k to work anyway.

The Hope + 20 adapters are around $40-45 from memory and you can pick up a new 180 rotor for around $30
