Look at the brake. You should see a finish flaw,thats where the pin was welded over. Dremel off that weld to reveal the pin. the pin will be a pin, or a screw. If its a screw, just back it out. If its a pin put the Brl in a vice, put a big wrench on the brake and wiggle the break back & forth just a little bit to loosen the pin until it will fall out. Its not difficult.
