Large brakes

I'm still waiting for someone to post up stopping distances for these big brake kits, as all we tend to here is 'they feel better' comments.

 

Well as 12 pot brakes are obviously 3 times better than the larger 4 pot OEM brakes then the stopping distance is obviously a third as much. Obviously.

Stopping distances won't be any better, until the inferior brakes start to get too hot. I suspect you knew that already? ;)

 

The KAD/UK setup on my current (MUCH faster) Supra were good & strong at the Nurburgring this year, whereas I'd cook the J-Spec ones on my stock TT last year quite easily and early in a lap.

Deceleration is down to tyre grip. If the brakes can lock the wheels (invoke ABS) at a given speed they are able to extract the maximum deceleration from the tyre grip.

 

Bigger discs and pads help with heat/effort management and affect bite/feel/friction.

 

Pistons distribute pedal force across the back of the pad...you only need enough pistons to cover the back of the pad effectively for even pressure distribution.
