- - RLX Brakes (https://acurazine.com/forums/3g-rlx-2013-412/rlx-brakes-882876/)

Whether they actually did anything or not, I was always enamored with the RL brakes, 12.6" ventilated disks front and 12.2" ventilated disks back, 4 piston aluminum calipers up front, and a single piston aluminum units in the back http://acuranews.com/channels/acura-...ura-rl-chassis.

I have always had single piston brake calipers, otherwise, but the RL brakes seemed exceptional, especially in their pad life, with 70K miles not being abnormal for the fronts, and 80-90K for the rears. I took the RL to the track once, and they did not seem to have the fade problem the old 2G Legend had.

I notice that the new RLX has a much more pedestrian brake set up, single piston calipers front an rear, smaller diameter 12.3" ventilated front rotors and 12.2"solid rears. Not sure what the caliper material is made of. http://acuranews.com/channels/acura-...specifications

Sort of like going backwards...we will have to see what the tests say....

I guess new owners will not be having front wheel fitment issues of the 2G RLs!

obviously the P-AWS system will take care of everything and the car will stop on a dime.

^^ Sort of like skiers (well, at least lessor ones like me :D) using pizza* to stop? It's actually kind of clever, now that I think of it.

*toe-in

you wouldn't need to use Pizza if you had P-AWS.

somehow I don't understand how a car looking like it needs to pee would increase the contact patch between wheels and the ground in order to stop faster.

I thought max contact patch = max traction

i thought the rear toe-in under (heavy) breaking was purely a stability type of thing.

That is one of the modes, but it also seems as if the rears turn in phase or out of phase with the fronts, depending on speed, and may adjust independent of the other wheel depending on the handling situation...

To the OP, I thought the same thing. I really like the brake on my 2005 RL. I, too, thought that they were going backwards.
I wonder if it is simply not offered on the 2WD version and maybe offered on the AWD version? Maybe?
