On my 1941 Chrysler C28 with the Lockheed series 1 brakes I am having issues with proper bleeding
I rebuilt the front brake wheel cylinders and replaced the flex hoses and shoes. The new shoe brake material is thinner than the old shoes by .05 of an inch, but it does cover the entire shoe on both sides compared to the old shoe that only had 2/3 coverage on the trailing shoe.
I have none of the measuring tools to set the brakes. I did cut a slot on the anchor pins, so I can adjust them when the hub is on. I adjust the lower anchor pin cams to get slight brake drag then adjust the upper cams to get slight drag again. I did this on both front brakes, master cylinder pumps good, using DOT 3 fluid.
I have bled the brakes and tried adjusting the cams to improve brake pedal firmness. The on first brake application the brake pedal is soft and travels near to the floor, a couple of pumps and the braking and pedal travel is acceptable.
You can see in the photo that the fluid hole is half way down the cylinder. I am thinking that there must be some air being trapped at the top of the cylinder when I am trying to bleed?
I was thinking about putting a side of the car in a ditch to get the hole near the top. Hopefully some other easier tips.
Thanks for you help.
