[#2387941]

After fitting some new brake leavers to my X bike, i've clearly adjusted the brakes in doing this, i now get a mental amount of brake/fork judder! i've had it before on these forks (ec90x) but i kinda just set up the brakes again and it vanished. But, after all i can think of, its back! and worse. Set up is a 60cm frame with the above forks plus an fsa h/set, Thomson stem, Salsa bars and SRAM carbon ss leavers. I'm running Aztec blocks.

Any advise?

Lots of toe in and make sure the headset is tight enough.

Lots of toe in and
.... make sure the trailing edge of the pad touches the rim first.

some people have a lot of success with this type of thing;

it stops fork flex changing the effective cable length and applying/releasing the brakes (which is what causes the judder.

Long cable drop contributes to this, as the forks flex you get the cable pulling and increasing braking effect. Folk have reported success with fork mounted cable guides/hangers, but not all forks have a hole in the crown for this.
Mine don't so I have to use loads of toe in to prevent this ABS like judder.
Wwaswas beat me to it by seconds!

I actually found that the judder on mine would go away on long alpine descents - such as coming off the Col de Joux Plane and Col de la Colombiere.

i had this something terrible on my pompino after fitting a kinesis crosslight fork, lots of toe-in cured it
