Master cylinder/ Back Calipers
Was wondering if anyone had instructions or video tutorial on how to change the master cylinder on a 1978, what all has to be done as far as bleeding it ( if need be) and how to do, any tips and tricks...and if I need to bleed it, is there some kind of kit available....can it be bleed on car or does it have to be done before installation..?? Had mine changed about 2 years ago and do not use car very much ( maybe 150 miles in last two years)...but seems to be weeping fluid where it bolts to the brake booster...someone told me it could be a rear seal on the master cylinder...???? Don't know since for all practical purposes its basically new....and I don't know much about them....
Also any suggestions on changing back calipers...I know the back drivers side is not working right....
Sorry for all the questions...and thanks for the help...

Make sure the weep is from the back of the master and not the back of the master cover.
You have to bench bleed the new master, there are kits consisting of plastic nuts and hose which recirculate the fluid back into the master as you are bleeding it. After the install you will have to bleed all four calipers, dont forget the rears have two bleed screws on each caliper.
what exactly do you mean by the back right side caliper isn't working correctly? It leaks, uneven pad wear etc.

All parts are simple bolt off / bolt on. But that's where it ends. Getting all the air out of the lines is the most important / difficult tasks for many.
Here is an example of one step many don't do, I learned this after I removed my master cylinder to get the last bit of air out of the master cylinder.

Also I use air pressure applied at the MC to bleed. ( one man job ) like this.
