Installing new Master Cylinder Advice
 

So I decided that the old master cylinder was failing so I got a reman. MC.

I was looking for advice on installing the new one. Drum on drum, 1970 2wd.

Problems, things to look for, mistakes you've made to help me not make them, ect.

Any help is appreciated, thanks.

The main thing I can tell you is to be sure and bench bleed it per the instructions in (or on) the box....

I replaced mine when I first bought my 68 all you have to do to remove it is to disconnect the two brake lines and the two screws on the fire wall it pulls right just don't brake proportioning valve as it connects to the right sided stud. idk if you have a booster mine does not. you have to bench bleed the master cylinder which means you have to get all of the air out of the master cylinder. you can buy a kit or just push in on the valve un till theres no more bubbles then pretty much just blead the lines at the master cylinder and the wheels and you will be good to :metal::chevy::sumo::uhmk::uhmk::lol:

Mine came with the bleed kit and like the others said, definitely bench bleed until all bubbles are gone...:chevy:

Good brakes are one of my peeves. Bench Bleed for sure. I like to pump the fluid into a glass jar to view bubbles & make sure none get pumped back into the cylinder. You will still need to pump new fluid to all four wheel cylinders after install to ensure there is no air in the system. Start at the furthest one from the master first. Speed bleeders make it a very simple one man operation. Have done several this way. Well worth the $25 expense in my opinion.

All great advice. I would also suggest replacing the wheel cylinders at the same time.
