I have a 63 Chevy Truck with drum brakes. I have purchased a power brake booster for the drum brakes but I'm wondering if it is a mistake to do this or if I will need power disc brakes. I want to be able to tow a boat with this truck, but have never driven a truck with power drum brakes. Will the brake booster with the drum brakes work sufficiently enough towing a 26 foot boat. Thanks in advance. Richard
