All I have is "squish"...
I posted this over on the "Maintenance & Repairs" board a couple of hours ago because I thought that was where I was suppose to post that kind of thing & still no response & it's getting pretty dark here with bedtime approaching, so I thought I'd give it a shot here (sorry if it's wrong to do here, but I'm new & desperate 
).In a nutshell; I thought that I would knock out some very much needed maintenance items before the weekend got here, like the brake pads & shoes, as well as the power steering pump (which seems to be where I've gone wrong), & now I got NO brakes!
From what I've "searched" I need to bleed the PS pump to get pressure back to the brakes because they are somehow tied together, but I do not know which of the 4 lines on the pump is the "return" line (the one to the resevoir; the one to the valve body; or one of the two that connect to the fitting on the bottom, left side of the valve body??????) on my '94 'runner.
Please guys, I'm stuck here & seriously in need of help.

to get pressure back to the brakes you should bleed the brake line to get rid of all the air bubbles inside the brake line.
do a search for 'bleeding brakes' but since it is dark i have done the search for you:

I've bled the brakes prior to my doing the PS pump & now I've got nothing.
From what I've read, the brake/ABS system uses pressure from the PS pump to actuate, or am I wrong??
And yes, the PS works, just not the brakes.

I bet your master cylinder went out, or you have a leak in one of the lines somewhere. Look for puddles/leaking fluid.
I have no idea where the PS thing came from. Never heard of that connection.
When you pump the brakes, do you get some pressure?

No signs of any leaks anywhere & this is with me tracing the lines from underneath the truck off of my creeper.
I read about it here while I was re"search"ing to do the PS pump.
Yes, I can "pump" up pressure sometimes, sometimes nada.

"Yes" to both "EWAYota"(as part of bleeding the brakes & the finishing "top off") & "mt goat"(as part of my researching the R&R on the PS pump[note that while "Mohamed" mentions the "return/effullent line", he does'nt specify which one it is]).

Thanks all around, guys, & even you too, "Rocket".
I hope that this solves my braking issue, but it's too late for me to mess with now & I'm a little too tired to even try, "RedBull" or not.
Please forgive, I am, afterall, a "newbie" & damn it!, now I think that I've lost all of my rubber bleeder caps

The return line would be the one going into the side of the resevior. The banjo fittings are for the high pressure side. Here is the 93 truck FSM: http://personal.utulsa.edu/~nathan-...3fsm/index.html

Sounds like you have it under control but I thought I'd add- when I R&R'd my third members for gears of course I had to disconnect the rear brakes. I bled and bled and could not get a firm pedal. I finally bought a brake bleeder (actually I bought a MityVac) and REALLY bled them. Even then it took two times around, but it finally got them bled. These things can be a bit harder to bleed than some vehicles.

when bleeding brakes it is very possible to blow the master cyclinder from allowing it to have too much travel......
thus giving the impression your brakes are good and bled but on testdrive there are no brakes.....

Jim is right. It's easy to trash the master cylinder if you press it all the way to the floor when bleeding brakes. You can score the piston and seals in the M.C. allowing it to leak internally and not hold pressure. It's also very hard to get all the air out of the lines sometimes. Do a very careful job on bleeding everything again.

So did you bleed your brakes? You shouldn't have needed to bleed them from just changing the pads unless you for some reason disconnected the brake line. I agree if you bleed the brakes using the pedal method you could have damaged your master cylinder. Here is some good info on that: http://www.gadgetonline.com/BrakeFlush.htm

Um I think you need to bleed the brakes. hahaha Im teasing.
Glad to hear you got it all worked out.
Never new about the Power Steering pressuse affecting the Brakes. Cool to know. I Learned something today YIPPE.. I am so SMRT.

O.k., so I did'nt get around to doing the brakes today because I got hung up changing out the plugs that I thought I would do first to get them out of the way & then move down to the brakes, but it did'nt work out that way.
2, 4, & 6 were a breeze (as they are with little or no obstructions), even 3 & 5 were not all that difficult, but #1 almost killed me & took the whole damn day to do!
I bruised my hands trying to get that damn thing out of there & even my shoulders are killing me, though I finally did manage to get it out & change it.
I can't imagine what it was that went wrong, but that was the longest, dreariest, most difficult time that I have ever experienced doing a simple thing like changing out the plugs on any car I've ever owned or worked on. :cry:
O.k., done crying now & brakes tomorrow (damn it).
