SOURCE: how do you adjust the brake rod on drum power

First did you replace the master cylinder? If you did you should have adjusted the rod so that you have 1-inch free play at the pedal before installing. You would normally back off the nut just enough to get it loose then install the new one. For the drums you adjust the brake drum tensioned to the point that with two lug nuts holding the drum in place it slightly drags and that would be adjusted threw the brake drum adjustment hole. If you have one to tight it will cause the master cylinder to get hot so jack it up off of the wheels and see if you have one wheel that won't turn freely if you do that’s the one you got to loosen up.

SOURCE: how to adjust power brake booster for 2002 volvo s 80

There is no adjustment to the rod between the brake rod and the booster on a S80. If you are having brake light problems the first place to look is in the trunk for a bad fuse in the rear electrical module behind the cover on the left side.

If you have bleed the entire brake system, your most likely problem is the master cylinder.

SOURCE: Brake Master Cylinder Push Rod Clearance

I'm not familiar with the Saturn but the Dodge has an adjuster on the end of the push-rod and if that's the case with the saturn a small tool can be bought that measures the clearance. PN: CP 2003. Try kttp://www.jegs.com/l

Need to install brake booster
Does it have one to begin with? If it does, it's as simple as replacing the part. Unbolt and replace. There is a rod behind it that must be in place when installing. If not, there should be instructions with the new one you buy! Remove Master cyul. Do not spill fluid anywhere as it eats paint... Have to get the proper rod length and install it behind the booster. Hook up a vacuum line from the manifold intake to the booster with a one way check valve pointing towards the booster. Rod can be adjusted by pedal feel, but there are specs which I do not have on me! Mount master cyl. back onto booster and that should be it! Make sure there is room for the hood to close.....

Step by step instructions for changing my brake booster
Remove only the two nuts that secure the master-cyl. to the booster NOT THE FLUID LINES and tie the master cylinder carefully out of the way.Then remove the four nuts under the dash that secure the booster to the fire wall.Not forgetting the booster push-rod connection to the brake pedal.Remove the clip and the pin and now the booster should be free to come out.There are torque specs. for tightening the nuts when replacing if you have a torque wrench.Refer to Haynes manual from auto shop
Also I think the brake booster push-rod is adjusted at the factory but if it isn't it may need adjusting otherwise you could find youre getting overheating brakes after the installation.

Replacing brake booster in 2001 escape the push rod in the new booster appears to be too short are they adjustable?
Not that I am aware of. My book on the 2001-2007 Escape does not indicate any adjustment in that push rod. double check the part number against the part number that should be installed by calling another parts store and asking if they have the part and then compare the number they give you with the number you have. Make sure the brands are the same. The problem you may have is that a lot of stores assume that all parts in these year models are interchangeable between the Escape and Mazda Tribute. In fact many are since both vehicle were built in the same factory with very few differences. In fact the repair manuals usually list both vehicles in the same book.

1986 5.0 brake problems...replaced brake booster twice and master cylinder once....now there is no power to the brakes...the brakes are stiff while the care is off....but when the car is on the brake pedal...
Did you check and adjust the push rod that comes out of the booster, and in turn pushes the rod in the master cylinder??
If its too long, the piston in the master cylinder won't move back far enough to pull brake fluid in.
If it's too short, it won't contact the piston at all.

It doesn't move as much as you might think.
If instructions came with the new booster, they may address this, and how to adjust it.

Install power brake booster on 1988 ford ranger
REMOVAL & INSTALLATION NOTE: Make sure that the booster rubber reaction disc is properly installed if the master cylinder push rod is removed or accidentally pulled out. A dislodged disc may cause excessive pedal travel and extreme operation sensitivity. The disc is black compared to the silver colored valve plunger that will be exposed after the push rod and front seal is removed. The booster unit is serviced as an assembly and must be replaced if the reaction disc cannot be properly installed and aligned, or if it cannot be located within the unit itself.

  1. Disconnect the stop lamp switch wiring to prevent running the battery down.
  2. Support the master cylinder from the underside with a prop.
  3. Remove the master cylinder-to-booster retaining nuts.
  4. Loosen the clamp that secures the manifold vacuum hose to the booster check valve, and remove the hose. Remove the booster check valve.
  5. Pull the master cylinder off the booster and leave it supported by the prop, far enough away to allow removal of the booster assembly.
  6. From inside the cab on vehicles equipped with push rod mounted stop lamp switch, remove the retaining pin and slide the stop lamp switch, push rod, spacers and bushing off the brake pedal arm.
  7. From the engine compartment remove the bolts that attach the booster to the dash panel. To install:
  8. Mount the booster assembly on the engine side of the dash panel by sliding the bracket mounting bolts and valve operating rod in through the holes in the dash panel. NOTE: Make certain that the booster push rod is positioned on the correct side of the master cylinder to install onto the push pin prior to tightening the booster assembly to the dash.
  9. From inside the cab, install the booster mounting bracket-to-dash panel retaining nuts.
  10. Position the master cylinder on the booster assembly, install the retaining nuts, and remove the prop from underneath the master cylinder.
  11. Install the booster check valve. Connect the manifold vacuum hose to the booster check valve and secure with the clamp.
  12. From inside the cab on vehicles equipped with push rod mounted stop lamp switch, install the bushing and position the switch on the end of the push rod. Then install the switch and rod on the pedal arm, along with spacers on each side, and secure with the retaining pin.
  13. Connect the stop lamp switch wiring.
  14. Start the engine and check brake operation.

How to take off brake booster
Basically remove fluid from master cylinder wtih siringe.
Carefully remove brake lines with the proper wrench.
Remove master cylinder.
Once the master is removed you can see the bolts holding the booster on remove them and remove the booster. Installiation is the reverse.
Be careful of the push rod. Do not touch the adjuster nut on it until you have installed the new booster and mastercylinder and feel the need for adjustment of the rod. The only time I would touch it is if after bleeding you feel as if the brakes were dragging or pedal travel was extensive.
I strongly recommed you get a shop manual for this procedure.

Bad brake booster
If you know for sure that the booster has failed, you need to unbolt the master cylinder from it, (sometimes you can move it away enough to not even disconnect lines.) Then unbolt the booster from the firewall, disconnect the pedal linkage if connected to booster. Remove & replace booster assembly and everything else you you took off. If you didn't have to remove master cyl you are done. If removed, bleed master before putting back into service!
