searched a bit and doesn't seem like we got a definite answer.

It appears the AV6'rs have a single piston, but are able to upgrade to a a dual compliments of an NSX or Legend.

I Can't imagine us only have 1 piston front calipers, but it wouldn't be the first time Acura suprised me.

 

it's true... i've found 3 people saying the stock CL caliper is a single piston...

I see no reason that we can't do the same upgrade that the AV6's are doing...

sounds like for $120 we can new dual piston Legend calipers.

The legend calipers also seem to be more desired since one of the piston's is larger then on NSX.

 

I don't understand why more people aren't doing this...

Has anyone succesfully done it?

It's a 1 piston design .

what do you think about this swap Jens?

 

I replied to this in the other post about this conversion .

If it does nothing more then help eliminate the rotors worping, i'll be pleased.

 

A TL caliper piston (assuming 45mm diameter) has a piston surface area of 1590 sq mm. The Legend caliper pistons have a TOTAL surface area of 2512 sq mm (40mm x 2) (158% more) and 2267 sq mm (38mm x 2) (143% more) while the NSX calipers have a TOTAL surface area of 2034 mm (36 mm X 2) (128% more).

 

Yep...1 good-sized piston, rather than 4 slightly smaller pistons.

 

yah..i think it is single piston..
most of the cars are equipped with single piston brake caliper
..

 

True Beerknurd however the pistons are not a real piston .In fact they are hollow so only the edges of the piston apply pressure to the inner brake pad .This fact coupled with the fact that the brake pad has a steel backing allows the pressure to be concentrated on a ring rather than a total surface area .Knowing that the steel in the brake pads is not the strongest this may be why Brembo etc. use multi piston designs .Multi piston designs apply the pressure over more area of the steel backing plate evening out the pressure on the pad material .This in turn means more stopping power .At least that is how I see it .

the RS6 has 8 and i think one of the new porsches have 12

 

Damn! The Supra TTs have 4 or 6.
