AP 6 pots juddering...
 

Ok so wifey's classic came with the AP 6 pots. Disc's/ pads are unknown tho will check at some point. had it probably around a year ago that they started to judder under light braking at 60/70 mph. so did some research and pad deposits came up. needs some abuse. :norty: ok so off I went and cleared them that time. well its back again and having tried 4/5 100-5 runs they are still the same. as the car only does 2k miles a year which is only local runs we are thinking of changing them back to standard 4 pots. (Then if/when i get a dedicated track car i will have some brakes) ;) But before we do are there any other options/possibilities of solving this?

Steve are they genuine AP discs ?

not sure at the moment will get one off one day to find out, If the previous owner is truthfull (have my doubts) then they should have been,.

Pad deposits will cause judder. I have Pagid Blue on genuine AP discs which are fine when used vigourously on track with well laid deposits on disc but are juddery for a couple of hundred miles after with normal use on the road. Once the deposits are worn off they are OK on the road. Sounds like you're in between and your "clearing" has added deposits and set you back. Try using normal for a couple of weeks.
