Hi, I had been getting some severe juddering under hardish front braking. I assumed the brake discs were worn out and warped so starting pricing replacements. As I wanted to be sure it was worn brake discs and not something more serious, I did a bit research on the net. I came across the possibility that it could be because the front disc bobbins were seized. I went and checked the discs and, sure enough, the rotors did not move and the bobbins were seized with no free play. After watching a few videos on how to solve the problem, I did some work on the bobbins to free them. The brakes now work fine with no juddering. I am sure this is something most people on here know about, but just thought I would pass on what I found out, as I didn't know. Cheers, SFH.
