Hi there, have a big disk kit, seperate bell and disk with AP 4-pot.

Feels fine during intermitant light braking (M-way).

However after one medium to heavy stop, the next application is a juddery horrible affair.

Does this sound like a disk on the way out? They are new and bedded in correctly.

I had assumed that a warped disk would manifest all the time, not just when hot.......

any comments?

I think the discs are warped. The juddering will at first only occur when hot, but as it gets worse it will happen all the time :(

.....THanks for the info......kinda what I thought!!!

Presumably this implies a dodgey disk in the first place.

Religously bedded the disks in, put them through a number of heat cycles...only done about 2K miles on them. No back roads, no track days.......bugger!
