I have read Nissan 4 pot calipers are a upgrade to the 6 pot Tokikos on the ZZR600. Any feed back on this?
nfloor Your a riot dude. They offer better stopping power.Nissin. Not Nissan. Nissin. It's engraved on the caliper. If you can't read you probably shouldn't be re-engineering braking systems. Just a thought.
Six-piston calipers were designed primarily to allow for incremental pad replacement for wear and type on the leading vs trailing pads. If you're not doing endurance racing they offer limited benefit.

The Brake Man - Brake Truth #1Although almost all road-going vehicles have only two brake pads per caliper, racing calipers utilize up to six pads, with varying frictional properties in a staggered pattern for optimum performance.
BigBrakesCalipersAdding more pistons to a brake caliper means using smaller pistons, elongating the caliper, and adding holes in key stress locations of the caliper.
Using smaller pistons means the overall combined piston surface area actually decreases; resulting in less, not more, clamping force.
But ok, if you insist, here's your Nissan six-piston caliper. Mounting it should be no problem for a genius like yourself:Another design usually incorporated with multiple piston calipers is differential piston size. The goal here is to further even out the pressure on the pad. This is done because the leading edge of the pad tends to "bite in" harder than the rear causing differential wear, thus a smaller piston is utilized in the front.
