if you had pressure in the lines then the pedal wouldnt go all the way to the floor

get a buddy and bleed them the right way,  doesnt matter what order you do them if you do them with a helper

Will the star adjuster fix its self or do I have to do it? Cause When I put the shoes on I threaded it all the way in. Its a freaking monsoon outside right now s I will prolly have to do them sun after work.  How many times shpoud I bleed them?

if you have a buddy work the pedal and you under the truck  it should only take one time,   but the bleeders have to be tight  and only opened whgen he is holding the pedal down firmly

yeah thats what we did last night. I put the truck on a rack and we bleed them. My friend was under the truck in the pit and I was holding the pedal. Could it be something else?

ok  you are 

pump brake 2-3 times, mash and hold,  buddy opens bleeder, then tightens,  then you pump and hold again, he breaks open bleeder, if no air then tighten then you pump while he moves to next wheel,  if air then repeat till no air

Same problem, today had close call on the way to autozone. I bought and installed a master cyl. Same problem only when the truck is off I have pressure. b4 I had none even with the truck off. Now I have pressure when the truck is off after I pump it up. I went back to AZ and they said it was my slave cyl. so I bought one of those. I have an slipomatic still till wed. where I begin the swap to 5speed. this is my daily driver so I have to take it to work everyday. I really need to figure out whats up. I bleed the whole truck after the master cyl install. very little air in the lines prolly from the master install. Is there a slave cyl on my truck for the brakes? and if so where is it?

He doesn't?
I have a slave cylinder on my 1985...it's on the passenger side of the W56.

Nevermind, that was my clutch slave cylinder.

If you are under the truck, and have a screwdriver thru the inspection/adjustment hole, against the star wheel, I believe, if you pull the handle down (either side), it tightens the adjuster. It will only turn one way without releasing the "lock" lever. Only adjust until you get a slight drag on the shoes. THEN bleed the system. The "lock" tab works with the e-brake to keep them adjusted, but will not self adjust from a very loose condition.

An easy way to check for a misadjusted rear system, is to have someone pump the brakes until you have maximum pedal height, and check the reservoir fluid level, then release the brakes. The level should NOT change very much as the brakes release.

Oh, and by the way, the piston assemblies in the rear braking system ARE called "slave cylinders", also known as "wheel cylinders". :gap:
It ain't worth doin' if you don't have to clean up afterwards!

Build it, break it, fix it, repeat until your wallet is empty.

as you are under the truck  you would need to roll the side of the star nearest you upwards,   you can put a jack under your axle so you can roll that tire gently. when you start hearing a drag sound  STOP ADJUSTING

Anyone who is saying RR first is wrong. The FSM states longest to shortest line, if you took a tape measure and measured the lines, you would see that it goes LR, RR, RF, LF, and LSPV. You do the LSPV last because it is the seconded highest component in the system and is connected to both the front and rear systems. I only use a bottle with a tube and some fluid in it to bleed my brakes, pressure bleeders work great, I am just to cheap to buy one. I have never been able to get a Vacuum bleeder to work right. That is why I stick to my tried and true method, a bottle and a tube. Stick the tube on the bleeder, crack the bleeder 1/2-3/4 turn, push the brake pedal three times, tighten the bleeder, check the line for bubbles. If the line has, bubbles repeat.
Correct bleeding procedure.



High dollar brake bleeder.

:nope: in theory  they are a "slave"  (ie you have a master  and a slave  to in a hydraulic system) but  in  automotive logic :hammer:  they are referred to as wheel cylinders for all brakes,  the slave cylinder is  strictly for a clutch components


ALTHOUGH,  in 60's era  large trucks, 2 to 5 ton, the brake system on those had a "master"cylinder on the firewall, a slave cylinder under the cab  that worked the vacuum booster.  it was a strange setup  but  worked, but that has no meaning at all here  :aaa:
