Title: Front brakes buzzing when stationary and wobbles :D
Post by: Mike01 on 18 August 2016, 08:23:32 pm: Noticed this today when sat in traffic, not just making a buzzing noise but causing the bars to vibrate....
As soon as I let off the brake lever it stops ....
Anyone had this?
Also got a fairly bad front end wobble at 110+mph (on track) that I have been trying to diagnose so I know the discs calipers etc are all tight, this is probably down to the 10k miles I have put on the pr3 tyres, mostly motorway so a bit squared off. Shame as there is loads of tread left. It's only Google telling me this, I'm no expert :lol
Cheers.

Would be my first thought also but I don't have ABS :'(

Will give that a try :)

Have you checked the front wheel bearings for any play as that could also be causing the high speed wobble.
All unlikely I know, but there must be an explanation somewhere.
Good luck with it.

Wheel bearing seems fine, not been out for a few days so will continue checking tomorrow during my commute. ...
