why didn't you rotate your pictures before posting them?
I've Used Cantilevers for 30 years, several types..
you want braking like someone put a broomstick in your wheel or what?
You wont be coming to a dead stop in a Race, just reducing your rate of speed .
unless avoiding someone crashing in front of you.
(and being rear ended by the rider behind you).
