Default Shudder when braking

Hey all

So I'm getting a slight judder through the steering wheel when lightly braking. I thought it was the discs but I've changed them and still the same. Any ideas?

Cheers JC

The front hubs can warp - meaning that even new discs can wobble


That being said I had a brand new pair of discs that were badly machined and vibrated like crazy!

if it's not discs and not wheels then it could be bushes but ultimatly if it's hubs you need to get them out and machined flat in the first and then, if you can find some, replaced with new
