pump the brakes look for a leak somewhere


I have done all of that & no leak

James Ramond

sometime a new master cylinder is very hard to get all air out , thats why they give you tubeing with it to bench bleed the master cylinder


From what I am reading you have rear drum brakes did you adjust the shoes out to lightly touch the drums. There should be a slight drag when you spin the axle.


I didn’t put a new master cylinder only ran new line up it Joe
