Ropey,
can you get a quote on your statement on brake wear for EMB 145 (I presume the same is on 140, 135)?
I can not bet my life on it but a combination of loads from thrust reverser + light breaking is on some other a/c resulting in LESS wear on brakes.
I presume you have hands-on experience for that statement, or if not a good quote.
It seems strange, however, they opted out thrust reversers. I've never seen that been done on comparable CRJ 200 fleet (1000+ a/c).
