Front brakes let me down trying to ride to Gibber for a evening ride, they must have been on their way out yesterday and I should have spotted it while cleaning the bike Crying or Very sad Crying or Very sad

Anyway, the L/H slide that holds the brake block stem is very, very loose with the brake block dropping almost under the level of the rim. The R/H one is fine. There seems no obvious nuts which would tighten this arrangement, however as I removed the both brake arms tonight I noticed a tiny grub screw (allen head) located in an awkward position behind the brake block holder arrangement.

Does anybody know what this grub screw is for, or if there is a procedure that is possible which will tighten the arrangement back to its original stiffnes.


I can't mess about with now as I have put everything away in my garage while I try to find some replacment brakes in my shed so i'm O.K. for Sundays Forum Ride Rolling Eyes Rolling Eyes

it will tighten the spring up in the lever, which will when the brakes are nipped together with the wire it should force brake arm out

Marty, this is not the "adjuster" screw on the outer part of the arm/boss area. This is a grub screw on the inside of the brake arm facing the wheel.

If you have orginal XT or XTR brake pads then it could be a screw holding in the pad. On the Parallel push v-brakes they designed them so once the pad was set then you could just change the pads without removing the holder. Link below to show what i mean.....

is this what it is? other than that then the only other grub screw i have on mine is for the spring tension.

No, I will try and post a pic up later of what I am trying to get across.

I should have done it last night but in too much of a state trying to find and fit a repalcement, which I managed to do. Had a set of Deore Canti's hanging about brand new and unused.

Very Happy Very Happy

Forget the pictures Rolling Eyes Rolling Eyes

I'm not getting the focus correct so things are blurred that need to be sharp.

I think that there's nothing for it but to clean the unit down and tighten up the grub screw to see what it does, when I can get to my tools.

It just seems an odd place to situate the screw, as if it does tighten the assembly I want it to tighten then why put it behind there where access to it is virtually impossible Question
