While receiving instruction in a BE35, a student experienced difficulty in stopping the aircraft. The instructor pilot pulled the mixture, but the aircraft rolled into the back of a PA44, damaging the rudder. Reporter states that the hand brake on the left was hidden from view by the yoke and the student's legs.

Narrative:
Whilst being taxied to an active runway, in a BE35, the plane collided with the back of a PA44. The PIC was getting instruction from me in the bonanza and he had already about 8 hours in the plane. There are no brakes on the r-hand side of the bonanza, so I would have no control of stopping. When we entered the taxiway the pilot shouted that he had no control of his brakes and couldn't stop. He was rigid in his seat with his feet hard on the brakes. The parking brake was hidden from my view due to the position of the yoke and the pilot's legs, so I pulled the mixture and the power. We slowly taxied into the back of the seminole and damaged the rudder. As far as I know nothing has been discovered regarding faulty brakes as yet, and although it appeared that he had as much force on them as possible it is my belief that he may have been asserting all his pressure on the middle of the brake pedals. I would recommend that if you are doing any training in an airplane with only 1 set of brakes, ensure that this sort of possibility be discussed with the pilot.

Title: WHILE RECEIVING INSTRUCTION IN A BE35, A STUDENT EXPERIENCED DIFFICULTY IN STOPPING THE ACFT.

Narrative: WHILST BEING TAXIED TO AN ACTIVE RWY, IN A BE35, THE PLANE COLLIDED WITH THE BACK OF A PA44. THE PIC WAS GETTING INSTRUCTION FROM ME IN THE BONANZA AND HE HAD ALREADY ABOUT 8 HRS IN THE PLANE. THERE ARE NO BRAKES ON THE R-HAND SIDE OF THE BONANZA, SO I WOULD HAVE NO CTL OF STOPPING. WHEN WE ENTERED THE TXWY THE PLT SHOUTED THAT HE HAD NO CTL OF HIS BRAKES AND COULDN'T STOP. HE WAS RIGID IN HIS SEAT WITH HIS FEET HARD ON THE BRAKES. THE PARKING BRAKE WAS HIDDEN FROM MY VIEW DUE TO THE POS OF THE YOKE AND THE PLT'S LEGS, SO I PULLED THE MIXTURE AND THE PWR. WE SLOWLY TAXIED INTO THE BACK OF THE SEMINOLE AND DAMAGED THE RUDDER. AS FAR AS I KNOW NOTHING HAS BEEN DISCOVERED REGARDING FAULTY BRAKES AS YET, AND ALTHOUGH IT APPEARED THAT HE HAD AS MUCH FORCE ON THEM AS POSSIBLE IT IS MY BELIEF THAT HE MAY HAVE BEEN ASSERTING ALL HIS PRESSURE ON THE MIDDLE OF THE BRAKE PEDALS. I WOULD RECOMMEND THAT IF YOU ARE DOING ANY TRAINING IN AN AIRPLANE WITH ONLY 1 SET OF BRAKES, ENSURE THAT THIS SORT OF POSSIBILITY BE DISCUSSED WITH THE PLT.
