It’s been a while since a proper update, and this isn’t that- I’ve got a brakes question: when I got her back on the road (late July), I installed a new brake master cylinder b/c the old one seemed to have failed and I couldn’t get great pressure. Now I’m 4 months into driving her and something is up with the brakes again: on Monday, the brakes went from a little soft on the first pump/ hard as nails on the second, to absolutely nothing on the first pump/ rock hard on the second. I inspected the lines (no evidence of leaks) and bled them (got a few bubbles, but nothing dramatic). The brakes were great after that Monday night test drive and Tuesday to work. Coming home Tuesday, they are back to zero on the first pump/ hero on the second. I “tested” the booster (pumped up brakes when off/ turned on and brakes softened a bit, just how the internet said they would with a functioning booster) and it seems to be working. Both my dad and my car guy neighbor are thinking master cylinder but can’t explain why I’d have the firm up on 2 after hitting the floor on 1. Any ideas? Would y’all agree with the master cylinder idea? It has a lifetime warranty, so all I’ll be out is some brake fluid and some elbow grease, but hate to tear it apart if it could be something else.
