On the 88' t2's, are the REAR brakes 1 or 4 piston?
 

just like it says? need an answer asap thanks.

1

shit, thanks

all rx-7's come with stock 1 piston calipers.. the difference is some have vented rotors

single, piston - floating

what does floating mean?

its means the disk is not hard bolted to anything.. it can move in and out a little. its supose to be easier on the pads i think. i didnt know our rears were floating.

It means that the caliper itself will move in order to apply pressure on the rotr. With a 4 piston setup, the caliper is just bolted in place, and the body never moves, the pistons do, in order to compress the rotors. With a floating caliper setup, one piston sqeezes on one side, pulling the other side of the caliper against the rotor as well at the same time.

I wonder why Mazda didn't put atleast a 2 piston on the rear caliper since the front had a 4? I know the ratio of front brake usage to rear usage is about 60:40, and I know the 300zx has 4pt in front and 2pt in back and those things can stop on a dime..

You dont really get any more clamping force with multiple piston setups. It basically just makes sure that pressure is evenly distributed across the entire pad, for better wear and breaking characteristics. The rear pad isnt nearly the size of the front one, so 1 piston caliper should do the job just fine. And I think my FC would out-break a 300zx any day.... ;)

300Z stopping?&nbsp You gotta be kidding me, right...
