Trike has set since early Nov. I put new tires on it and was taking it out, when I smashed the rear brakes there were none.. I pumped them and it started to build up pressure. I got home and had a friend help me bleed them. nothing seem to work. We noticed I left the E-brake on. I release it and we bleed the middle bleeder on the front brakes and when I started pumping the rear brake it went to the floor with no pressure and none would build up. We started over and the same. Any Ideas????
