I do not know how your cover would make the difference. Also you cannot get the rear drums off. It takes a special drum puller. Make sure they put brake fluid in it. Had a traveler from Germany who purchased a 59 the previous owner rebuilt the brake system and put in hydraulic fluid. Had to have it flushed out. Also check the bleeding of your system. Now here is the problem; You have two wheel cylinders on each of the front wheels. They are a pain to bleed. Sometimes you have to take the backing plate loose and rotate and tilt to get the air out. The best thing is to see if there is a local older shop around that know something about the brakes. Basically look for someone in their late 60's or 70's that is a car nut.
