Hey all

Been suffering from annoying, and getting to the point of dangerous, brake judder on my crosser.

Grab a handful of front brake and what power you get from the tektro frogleg brakes is wasted by horrid judder - you can actively see the fork flexing quite a lot! I cant really remember it being like this from new, so i presume it has developed as the pads have worn

Tried it with the straddle low, the straddle high, adjusted the toe-in - most things really. It could well be the forks, but i'd rather NOT spend money on forks if i dont have to 🙂

Any tips?

Thanks!

Tim

Change the pads, this has to be your first port of call. If that fails change the canti. If that fails the fork. Sorry.

Had the same problem with some Magura Julies-every time the pads heated up when they were worn-switched to more continuous edge discs ie no wavy rotor or V* cutout and hey presto no vibrations.

Had the same bother, not frog-legs, shimano cantis. I changed the headset-a cheap and nasty one- as the cups were flexing under braking! It was nearly unridable, put a richey WCS one in problem solved!
Try the pads too
It's a Focus CX bike

if your forks have a hole for a fork-mounted cable-stop then put one of them on

If you have had it for a while, another consideration is that the brake posts may be worn.

Sorry to resurrect an old thread but brake judder has blighted me recently.

I've tried to find a fork mounted cable hanger as shown by JoB above but I can only find them in stock in the USA and they don't want to ship them to the UK. I came up blank on Ebay and general Google searching as well.

Does anyone know where I can get one? Am I just really crap at searching?

Thanks,

Jim.
