yup, that's zackly how my boy does my deepender.the way that we test disco's, drop the front wheels into the rollers / chock the rear wheels at front and back / test front brakes / drive vehicle forward /chock front wheels / test rear brakes / to test handbrake (as directed by our local VOSA examiner) start the rollers together pull up gently on the handbrake until the brake indicators show 200kg then let the handbrake off without locking any wheels, or we just take them out on the road with the old decelerometer and pull up on the handbrake gently to slow the vehicle down enough to register above 16%
2 wheel rollers are fine up to 5Km/hr and yer brake tester doesn't exceed that.
