I know the drums are stamped steel... and heat up much faster and warp & fade, as well... but unlike the model A ford parts... there are No Cast Iron drums that inter change with these steel drums.... Going down this long mountain road that drops 2,000 ft in 2 miles... I just put it in first gear and use the engine compression all the way down the long steep hill....using brakes only rarely... when the compression is not enough to keep the engine from revving too high... so I have adjusted my driving habits in many ways to accommodate the cars limitations..... i drive like they did in 1934..... Slow and easy... never in a hurry... out for the ride... not the destination....
I bought the softer woven lining material... that has soft brass fibers woven into it.... They are still seating to the drum....I am sure they will improve with more use..... I love driving this car... it takes me back to a time where mankind was functioning at a much slower pace... Less stress in peoples lives.... No Hurry... No Worries.....
I am NOT buying the vacuum devise...I will be putting the money to better use elsewhere.... like for more gas.. to drive it more often...
