do i need to keep the master cylinder resevore closed while bleeding each wheel?
is there anything things i should know about this that is tricky

i had my girl friend pump the brakes three times and then i loosened the bleed screw and looked for bubbles i put a 1/4 inch clear rubber tube over the bleed screw and then ran that screw into a cup of brake fluid.
and then closed the bleeder screw then told my girl to let off the brake after the bleeder was closed

but the pedal is still the same.
what did i do wrong?
i put a new cylinder on the rear drums because i broke a bleed screw off
and i put a front caliper on because of the same reason
when replacing these parts could there just be alot of air in the system.
so i just need to keep on bleeding all fours untill it gets better.

 

No, you don't need to close the MC reservoir. You just need to keep it filled.

Did you bleed in any particular order?

You should bleed all four corners until the fluid comes out clear and bubble free. The technique sounds right. Make sure your helper isn't letting the pedal up before you close the valve.

The original post just sounds like you quit too soon. Gotta keep bleeding until you get no more bubbles. Maybe 1/2 pint at each corner? Sometimes the rears take even more because of the long tubing.

 

Maybe this is a dumb question (and I have lots more of them)- Did the pedal go all the way to the floor when you opened the bleeder?
Otherwise - do what the others say.

 

Pedal will drop to the floor. Hold it there until the bleeder screw is closed.

Pro-tip: Bleed your clutch while you're at it. Clutch pedal will go to the floor and will remain there. Pull it back up with your hand.
