Stovebolt.com Forums The Parking Lot Big Bolts 2 1/2 ton brakes

Not sure what the new one is, I was just told its a new one for the truck. Probably should have taken the time to pull it apart and measure i guess. Might be my next move.

Your Master Cylinder should have a bore of 1.5".

Brake lines rubber and steel fail from the inside out, they might look good on the outside but are one push away from failing from the inside.

Did you bench bleed the Master Cylinder?

Did you bleed the Hydrovac's two bleeders first before going to the wheels following the service manual instructions (1955 book)?

Bled the hydrovac like the book says, didnt bench bleed the master tho. Just fill it up and screw the cap on then tip it so the outlet is up and pump it?

Next step might be tracking down the original master cylinder since im pretty sure I cant buy one right? And cant bore out a 1.25"? While im at that ill replace all the lines i havnt already.
Anyone happen to have modern part numbers for the rubber lines?
