Hello,

I have already installed a new fork in my bike (rs reba sl) and I have a problem with the brake because the brake pad is twisted and touch the disc. I've checked the installation and I think it is alright. I tried to adjust the brake pad braking it before tighten the screws but it is imposible.

The brake in the old fork (fox vanilla r) was working prefectly.

I attach pictures from the problem.

Could the problem come from the fork? Could the adapter be damage? Thanks.

Getting the tabs faced may help, though it seems the actual calliper is bent, perhaps it was somehow bent while on the Fox.

Get your disc tabs faced.

Is that wheel dropout on left llower leg of Fox straight?Looks like it is bended to the left in the pic.Mayby that could be reason for brake to work ok on Fox? Result of crash?

Half a mm can make a world of difference - it equates to more than that at the pad edge... as if those tolerance weren't really tight already. It can't hurt to get the tabs faced.

I can't "CLEARLY" see that. A whacked out disc tab makes things look the exact same way. Have you looked at a disc caliper lately? There usually isn't much space between the pads. Reset the pistons and center it. True up the rotors. Once set up properly, it won't rub.

And how do you know it's not because the adapter isn't sitting straight because the tabs are not perfectly parallel to the rotor plane? Which is what it looks like to me... You see the rotor from dead on, but you can see the side of the adapter.

If you couldn't get your Juicies to run drag free, that's not a problem with the brakes.

Hello and thanks for the answers :thumbsup:

My english is not very good and I am not sure to understand all yours words, so I attach this new picture:

is it ok??

If I get the tabs faced maybe it could weak them?

I have installed the brake in the fox fork and I have no problem to adjust it so I am sure that
the problem is coming from the reba. The tuesday I will try to install another brake to confirm it.

This is not an uncommon problem with Rock Shox. The disc tabs are very rarely parallel to the disc plain, and the solution is to face the disc tabs. The result is exactly what you are seeing, the disc caliper and adapter sitting cockeyed.

Take it to a shop have the tabs faced and you should be ready to roll.

happy trails...

Check to see if the adapter is sitting dead flat against the disc tabs. I had a Magura Ronin and an Avid adapter that did not get along, the adapter touched the cast gusset just beyond the spot where the tabs were machined flat, it needed to have a notch filed in the adapter to sit flat.

I wouldn't go so far as to say that they're rarely parallel... I've seen it on makes and models... It just has to do with casting flaws and paint over/underspray.

Facing will not weaken the tabs, it removes a small amount of material to make the tabs parallel to the plane of the rotor.

The advice to make sure that the adapter sits flush against the tabs is good.
