Thread: Brake Booster riddle - can you solve it?

The only thing i can see that needs attention (baring in mind i can only go on the information and photos shown here) is that 18" of rigid brake line seems to floating in the air without any type of fixing. It then goes into a union which again seems to be floating about. Not exactly 'scary!', but could use some attention.
It's good practise to fix the rigid brakes lines to the chassis every 8-10" if possible. Your rear lines could possibly fracture (with vibration) at the point where the two join. I can see why this was done, if you said you had a broken line into the master cylinder then, it looks as if only the front section was replaced.
With regards to improving the efficiency of your system...(there has been plenty of advice so far).
But before you go and change things and spend money unnecessarily, I would start by getting the linings adjusted up so the entire length of the shoes make contact with the drums. Do a few miles and get them 'bedded in' and re-evaluate.
The pedal ratio can altered fairly easily, get someone to weld up the orginal pivot hole and redrill accordingly, or you can probably use a smaller bore master cylinder once you know which one you have. I would consider examining the rest of the brake lines and get them replaced if workmanship looks 'dodgy'. You may have to anyway if it turns out they are connected back to front.
BTW i'm learning things from this thread also
Cool cars are even cooler when you know everything is well engineered enough so you know it will never let you down.
