If the funny pedal feels like its pulsing under your foot then iv had this problem.

its all related to the ABS, it was happening on mine when i had rebuild the front bearing/hubs and there was grease in the teeth of the ABS rings on the front end... removed ABS sensor cleaned end... got air line out and blow the teeth out on the ABS rings problem sorted.

i know that you proberbly wont of touch the ABS when fitting new brakes but just something to think about.

Cheers James.
