ABS sensor works off the wheel bearing so if you dont change the hub you havnt got a prob. Ive got a boca an i really need some better brakes. I understand the 312mm conversion is good but wat is it off an has anyone got any vag numbers? I work for seat an wouldnt mind gettin some brand spankers. I know leon is reduntant cus i have measured them and they are running the same as a mk2 octi vrs ie too big.
Thanks
Phil

this is what i have been after. i dont want second hand brakes and an out of the box solution seems to be either impossible to find or if you do (e.g GT Brembo Junior) is too expensive. I am trying to get hold of someone at AP to see if I can buy new parts from them but they seem to be hell bent on not making money as 3 emails and 2 phone calls directly in to the sales team and i havent heard a peep :think:

If your going to pay brand new proces for 312mmbrakes your better off getting an aftermarket solution from the likes of Brembo, same cost even to us.

If you work for SEAT just look up front brakes for a 2001-2005 Leon Cupra.

Carriers are about 120 each, calipers iirc 200 each plus VAT, then 2 discs about 35 each and pads 60ish.

MKII Octavia is 5x112 so discs are no good and as said the carriers are different, different bolts, spacing and offset.

Have a look at your current calipers - do they have FS III cast in to them ?

If yes then you are going to need the front hubs as well as the brakes.

If your brakes have a spring on the outside then you can go for the 312 conversion without changing hubs.
