It was time to replace the rear brakes (drum) on the Ace, so I ordered in some shoes, they were slightly wrong, but the bench grinder solved that issue,
The real issue is with the cylinders. Stock replacements were damn near impossible to track down, with only one supplier out of four having a listing, and at $50+ each! Politely told them what they could do with those cylinders, and scored some off a Justy that matched the dimensions for much much cheaper.
After bleeding the brakes, my pedal guy (dad) said the pedal felt nice and firm. Awesome!
But the shiny facade fell apart when I went for a test drive, to reveal a turd of a braking system.
The pedal is spongy as hell and takes 3 inches of travel to start really stopping...
My theories:
>there\'s still air in the lines
>a cylinder is leaking (it looked sorta wet in there when looking through the adjustment hole)
>cylinder bore size is causing the problem.
The stock cylinders are 9/16, absolutely tiny and will probably grenade when I install the hydro-handbrake. The new Justy ones are 3/4 bore, much better. But I noticed my master cylinder is only 3/4 bore and I\'m thinking its just too small for those big cylinders, and can\'t pump enough fluid quickly.
I\'ve ordered a new pair of cylinders, and I\'m pulling the drums off in the morning to check for leaks, but some input from someone that knows a bit about hydraulic systems would be great, I\'m just a self-taught garage cowboy.
