[Closed] Brake Judder

pretty hard to say with no clues to go on!

Things to check to start with:

- tightness of centrelock lockring
- tightness of adapter/mounting bolts
- contamination of pads
- tightness of QR/hub bearings
- tightness of fork bushings

i'm getting this. Nasty growl from the rear under braking. Like a rusty trombone tuning up.

I think I need fresh pads to be honest as everything else is tight (although the rear tried to jump ship the other day)

I had a similar problem with Hope mono minis, and in the course of events i'd changed frame,forks,headset,hub,rotor and caliper (I wasn't specifically looking for the cause, just upgrading), and still had a judder.In the back of my mind,i'd always suspected the rotor, as the braking surface doesn't comprise of two concentric circles,more a series of tapers between spokes(just like the Shimano centrelock rotors), so I thought i'd try a set of Shimano XT 6 bolt rotors(which have a concentric brake surface)and all traces of judder disappeared instantly.If you can borrow a wheel fitted with one, it's certainly worth a go.

could also be the rotor is slightly warped, or, is cleaner in some areas than in others. give it a good (but uniform) rub with 240 sandpaper.
