    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 😥 😥

    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 🙄 🙄

    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

    or atleast i think 😉

    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.

    😀 😀

    Forget the pictures 🙄 🙄

    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 ❓
