Recently had to have my truck towed home because the master cylinder push rod broke, replaced the master cylinder, "didn't bench bleed it", started bleeding the system, and now the clutch pedal will not depress all the way to the floor, as well as no more fluid is coming out of the bleeder valve. Plenty of fluid in the system. Clutch feels normal until it's about 5 inches away from the floor, can't even get down far enough to start the truck. I really need some help.

 

A couple of questions,
we do/do not know why the push rod broke?
Was the replacement rod the same length as the original one? If it is too long could be part of the problem.

 

Just checked, it is the same length. I pushed in the clutch and started my truck, put it in reverse, took of the parking break, took my foot off the clutch but it didn't come out. Put the shifter back into neutral and pulled the clutch up with my toe, then tried pushing it down again. Moved about 3-4 inches then got stiff and wouldn't go all the way to the floor, tried forcing it down, and that's with the pushrod end broke.

 

Think I solved it, after bench bleeding the master cylinder, bleeding the system for almost an hour, removing the hydraulic line, and f%*$&#@ up the coupling, finding that the slave cylinder is clogged, or is mechanically broken. Now to find a decent mechanic to drop the transmission and fix it for me. . . .

 

Don't feel bad, you aren't the first to have this happen to you. And,, you won't be the last ! Those combo slave units can be a pain to bleed.
