1965 Valiant low brake pressure

It didnt necissairly "Blow", the car started pulling to the right since the left front wasnt braking and thats what got me to check it out and is when I noticed the leak then when I took the brake shoes off the Right side (got fluid on the left shoes so replaced all the front pads) and once the spring pressure was off of that WC fluid started dripping out the boot, so I replaced that one too. So no, it didnt go straight to the floor, it actually still stopped fairly well just pulled really hard to the right.

Took the car out to the local friday car show and it stopped great the whole time so Im 99% sure everythings back to normal. Probably gonna replace the rear brake assembly's soon just because it seems like a good idea.

Ill give you a series of Brake related events just to make sure I answered the question. Car runs and stops fine, front left rubber hose blew a few months ago and lost all pressure, fixed that and everything was back to normal,Then last week I started losing brake pressure while applying brakes (the car would slow down and the pedal would keep sinking till it was on the floor) and having to pump brakes Diagnosed as bad MC, replaced that and everything was back to normal for about 3 days untill the left WC started leaking and the car started pulling to the right but kept pressure (as I stated before), replaced left and right WC and shoes on front wheels, and thats when I came on here since I couldnt get the brakes working correctly, Im pretty sure what solved it was slamming the brakes really hard then tightening the adjusters all the way then backing off and thats where im at now (after slamming the brakes the left side adjuster took alot of turns to get all the way tight when the left took only about 1/4 as much). I went through about 3 bottles of brake fluid from the start of the story to the end.
