While waiting for the carb kit, my brother -in-law and I took a look at the brakes.
Things looked good inside all of them, except for the driver's front brake cylinder. One of the boots had a small bit of moisture in it (see picture) so I'm assuming it's leaking? If so I will replace it.
All the shoes had plenty of meat left on them. We messed around with the brake adjustments a bit but most of them felt pretty good already. We tried adjusting the eccentric on the passenger front (the first wheel we took off), but it wasn't operating like it did on my car. Overall things felt pretty good on all of them.
The pedal is pretty soft, and the brake fluid has been sitting around for 7+ years, so a brake flush is next. I ran out of brake fluid, so Saturday morning we'll do that. Hopefully that gives me a nice firm pedal.
