If your brake will lock your front wheel, at speed, with a reasonable amount of hand pressure on the lever, there is really no purpose for "maximum bear trap like clamping power". With any decent brakes your wheel is going to lock well before you run out of "clamping power". The big difference in types and quality of brakes is not at lockout, but how smooth and controllable the transition is from lightly feathering the brakes to maximum deceleration. Notice I said "deceleration" not lock out as your maximum braking comes at the point just prior to the wheel breaking traction and sliding. Power sliding is not efficient braking. The precision with which you can apply pressure to the brake pads and the return feel you get determines how accurately you can keep a bike at maximum braking without locking up the wheels.
