Master cylinder bleeding
88 F150 - 4x2 w/ manual trans and 4.9. Anyway, the brake pedal nearly bottoms and grabs the rear brakes ( which are significantly in need of shoes),
Bottom line, I think that the Master Cylinder w/ internal proportioning valve is the culprit. Ford's shop manual seems to suggest power bleeding the MC after replacement. The only other MC I did was a bench bleed followed by a regular bleed. Will this work? Truck is not worth much, but I will do a reasonable repair to keep it rolling.
Thanks!!!

Sorry, I should have been clearer. The brakes were fine, and then they suddenly dropped to about a half inch from the floor. I think that only the rear ones are coming on -- and yes they are low. However, I think that the master cylinder,
(which supposedly has a proportioning valve in it) is probably bad. I have brake system fail lights now as well. I just wanted to know about how to bleed it.
Thanks!
