Re: Drum Brakes
When I built my car I set it up to footbrake. I have a Ford 9" in the back and used 2 sets of shoes so i could have all long lining covered shoes. Then I took the wheel cyls and with the help of a local parts store found the largest diameter wheel cyls that fit my backing plates. When footbraking the rear drums have great holding power as they are self energized, the shoes try to rotate against the drum which in turn forces them out harder as the lead shoe grabs. Also basic hydraulic principles, the larger the wheel cyl bore the more the hydraulic line pressure is pushing the shoes.
