By brake torquing I mean like at a race strip where you hold the brake pedal down and give a little gas at the same time to build up RPMs. Pretty much if you got you're foot on the brake and then start pushing on the gas while in drive the tranny is trying to move the car but it can't hence straining it.
Manual downshifting is what yo're doing and is O.K. if done at resonable speed for a short period of time. I'd highly recommend changing the brakes ASAP if its that bad that you have to manual downshift.
