What causes brake judder?
Discussion
Got a MK6 Ford Fiesta which judders slightly through the steering wheel when braking. Nothing major, just annoying.
I've checked that both front wheels are true and round by sticking a pencil to a jack stand and rotating the wheels. Hardly any deviation from the tip of wheels, 0.5mm at most. Also did the same with the disks. Everything it round and true. I checked on both sides of each wheel and disk.
No play in any bushes as far as I could tell. I grabbed the various suspension components and gave them a shake, but no movement. Drive shaft has a bit of play if you push it backwards and forwards towards the transmission, but it is the same on both sides.
Any ideas what else it could be? I did notice that the inner side of the disks were worn slightly more than the outer side. Same on both disks.
Don't think it is a tire balance issue - just had new tires put on and it is exactly the same as it was with the old tires. It seems to have a slight judder when moving normally, but gets worse when braking.
Thanks!
