Help me pick front calipers
You do know the KH 4 piston system was replaced by a single piston floating type caliper. Maybe the engineers knew something.
Yes, that single piston calipers are cheaper to produce and less likely to leak. :violent1:
Multi-piston set ups allow for a more equal clamping force over the area of the pads, which gives better braking. Of course, every additional piston is another seal to possibly leak. But that was probably more of an issue with the KH's than it is now.
You do still need to pay attention to the overall piston area, as that will make a big difference.
Still, if you have 12.19" rotors on the back, I'd run at least that size on the front. The larger rotor will make a bigger difference, which is why going from 10.87 to the later 11.75" rotors is a popular upgrade even though the calipers don't change.
And if you want to unload those AR brackets, let me know. :wink:
