Looking for more brake power

[bronco]

I'm looking for alot more brake power. My car doesn't stop as fast as others seem to do.
I have calibrated my esc on several occasions setting all transmitter settings to standard.

Is brake power related to the motor used ? Or is this independant to it ?

Example :
Esc LRP TC Spec brakes are ok, but could use more. Motor is a GM 9T Delta wind used in a HB D4.

Esc Xerun 120A insufficient brakes! Motor is a GM 12T Delta used in a X6

Tips are welcome
