    On my last run out, I felt that my rear brake operation wasn't as it should be. A quick check confirmed that pressure on the foot lever was not transferring to the brake.
    Sticking calliper piston/s was my first thought but on further inspection, requiring disassembly of the footpeg and lever mechanism revealed that one of the two small countersuck retaining screws securing the push rod mechanism to the footpeg had worked loose and was fouling the footpeg bracket. The loose screw had gouged a score and created a lip (steel vs alluminium) in the footpeg mounting plate that prevented brake lever travel.
    Cleaning, thread lock and copper grease application now has restored full function to my rear brake.
    The moral of this tale is, Check your brake operation chums and if it's a bit 'sticky' don't assume it's the calliper!

    My dad and Peter would go over ever single bike before delivery. It was very common to find loose bolts. If you go back on the forum I probably posted it 100 times. And things like this post are valuable. Thanks for posting. These bikes are hand built so human error is very possible. But the hand built is the attraction too.

    Hand built isn’t really an excuse for this kind of failure Richard.

    Even Toyota’s are hand built when it comes to final assembly.

    And not many Toyota’s make it to the customer with loose fasteners!

    These kind of failure modes are eradicated by robust application of ‘standardised work’ and good process design driven by systematic Problem Solving.

    It’s not rocket science. It’s just that it takes effort, and some companies choose not to do it.

    Play fair boys, my bike is three years old with 7k plus enthusiastic miles on it. My post is intended as a sevice/safety awarness post, not a bitch about build quality.

    Fair point. I was responding to Richards point about general loose fasteners though Stuart, not your 3 year old screw.

    How about giving your fasteners a dab of the Loctite 290 when you first go over the bike ?
