The master cylinder has a slug inside that slides. It is there so if you get a leak in one of the brake lines, it moves to allow fluid to go to the other brake lines. Usually they never have to move and sometimes crud builds up around them. If they do move, the crud holds them in place. -- It sounds like your master cylinder slug has moved and stuck in place preventing fluid flow to your caliper. --- Here's a site explaining it - http://www.britishv8.org/articles/tandem-master-cylinders.htm
Here's another site. It has what looks like a bunch of handy links on the lower right side. -- http://www.ehow.com/how-does_5547495_master- cylinder-works.html
Thanks for the best answer click! Good luck with the brakes and drive safe.

If i had this braking problem in my repair shop, I would loosen up the bleeder screw on that right front caliper and use my vacuum pump to draw the brake fluid out. Make sure the brake fluid in the master cylinder's reservoir doesn't run dry while you are doing this. This procedure should pull fluid through the brake line and caliper plus it should also remove the air in the system. If that didn't work I would check for a pinched metal brake line then maybe the master cylinder, but that probably won't be necessary. Try the vacuum pump first and you'll probably be good to go. If you don't have one they are available at most auto parts stores for about $30 bucks or so. Best wishes.
It's not a plugged bleader, is it?
I have the same problem, and have traced it back to the abs actuator. It's not sending fluid to the passenger said at all? I'm at a block for me as I don't know what to do next
I have a 1990 gmc sierra v6 and the caliper doesn't want to release the brakes on the right passenger side I changed the caliper and rotor and brakes but it keeps doing the same thing.... brake lines look good too would really appreciate some feedback on this matter
