very good, i was supprised the A.P's was lighter giving there size.
However, do A.P match the calliper to the car? For instance, your master cylinder will only push XXX amount of fluid to work the calliper. So the insides of the calliper need to be matched to the master cylinder to give the same breaking force. (more so from front to rear when not changing both)
Alot of people say that the new break kit works better but this is normally down to the calliper being new and running a better pad over previous set up.
I know that there is one company that build there callipers to match the master cylinder on the vehicle, is this the same for A.P?
