One short section of steel brake hose needs a 9/16 X 18 fitting and the other line needs 1/2 X 20
Do you have a 1 & 1/8" bore M/C to go with your power brakes?

I have a ‘75 that had been sitting for a few years. Drive it home noticed right right caliper was leaking so replaced it. Drove it around for a bit no problems. Last week the pedal started getting mushy and the Red BRAKE light started coming on. After talking to a few people seemed like it may be a Master Cylinder Issue. Replaced the Master Cylinder today (did a bench bleed before installing) and then proceeded to bleed each of the brakes 1 by 1. Finally started her up and it’s worse than before.
not sure where to go from here but here’s a few things on my mind:
1. The other 3 calipers are original to the car, they don’t show any signs of leaking but maybe I should change them
2. the brake booster is original, however the car isn’t running odd so it leads me to think it’s fine.
any help or advice is well appreciated

Just wanted to say thanks to everyone. After chasing down just about every culprit I decided to purchase a pressurized brake bleeding system from harbor freight. Used it with my compressor and it made A WORLD of difference. Found a lot of crud sitting in the lines that did not come out before (must have been the culprit) brakes are nice and stiff, better than ever!
