bleed new master cylinder

[socalkevin07]

got new master cylinder from napa today..cost 170..(credit cards almost maxed) .....

I can't figure out when i bench bleed it before I install it...ok do i fill with fluid and leave the round plug on top then push in piston several times..or do i need to run a line from where the brake line goes back into the resevoir and then pump the cylinder....There is a solid cap on it..so i don't really know how many times to push cylinder in because i cannot see if their are bubbles still in the resevoir or not...very confusing for me..first time.

the directions that came with the unit show it done both ways but does not tell which way to do it.

At least is say's made in usa on the unit..maybe it will last a while.

thx for your help

Hook line from master cylinder back in the top of the resevoir , fill with fluid, push piston in and out a dozon or so times this will work the air out of master cylinder and won't run out of fluid while your proforming this task. Carl
