Hello, I am new hear. Recently picked up a heald tri-sport/ trike. It had no motor so I put a 8hp Briggs and Stratton on it. Spike with Ron Hubbard, he sent me the correct belt, put it on, started it up and it took of without me. I didn't realize the hydraulic brakes don't work. Afyer looking at the brake pump system, I noticed the rubber boohot is torn. Does this need to be intact to operate correctly? There is no leakes that ive noticed. How do I bleed the brakes?. Thanks Richard
