I ordered new wheel cylinders, brake shoes, and a hardware kit for the rear brakes.
Pulling the old pieces off was straightforward.
The first problem was getting the old wheel cylinders off. The bolts were siezed solid, and I could not get them off. I ended up having to drill the bolts out and chisel the heads off. There wasn’t enough room to get the drill in the right position, so I used a 90* adapter, and a bit of contortion to get the job done.
I cleaned and painted the old parts that were to be reused, and then it was a simple matter of reassembly.
had replaced the hard line on one side, the line on the other side was not budging, so I cut it off and replaced it. I bled the brakes with the power bleeder, and got a good brake pedal.
