The Vented disk discussion above got me thinking..
My classic '86 early efi does not have vented disks. Occasionally I have had brake fade (but only when seriously provoked by less than defensive driving style). The front disks have seen better days, so instead of putting a set of Paddocks cheapies (now less than £8 a disk!!!), I could put on some vented disks from a later classic.
I presume I would have to change the calipers (?), but that aside, is it a straight swap?
