The engine must have excessive blow by from worn rings or the PCV valve is plugged. They make a kit that keeps oil out of the booster it is a canister about the 2/3 the diameter of a coke can and about 1/3 the height. If you don't have one try finding one on an older GM car, they are all the same part. The filter goes in the large vacuum line to the vacuum brake booster.

SOURCE: 1997 FORD F250 XLT 4WD - Had a hard brake pedal with hardly any brakes while standing on them. Replaced booster and wheel cylinders at same time now the pedal is mushy and no brakes.

They need to be bleed again all four wheels but your vacuum pump may be bad since diesels don't have vacuum then have to have a pump, check that the booster one way check valve is good if you can blow thew it both ways it's bad, to bleed start from the wheel farthest away from the master cylinder pump the brakes 5 times and hold down then open the bleed valve keep doing this until you get clear fluid out of each wheel once you have done that if it is still mushy and you know you have vacuum re bleed with engine running this will help push more out with power assist. most like the hard brake pedal had to do with no vacuum check out the pump. You may also have to reset the 2 way check valve if you need help with this let me know.

SOURCE: I have a 94 v6 camaro and am missing a vacuum line

Sounds like, there is no power brakes if the hose is not connected to the brake booster. There should be a massive vaccuum leak in the engine. The brake booster vaccuum line is a major vaccuum. You should hear a hissing sound when engine is running. Find the hissing noise and replace as nessessary.

Vacuum pump hoses

if the hose is about 1/2 inch and about afoot long and has oil inside of it probably is an oil return line back to the sump. If it is clean inside it will go to a item requiring vacuum like a governor or a brake booster.

Oil in brake booster

The vacuum is created via a mechanical pump driven from the cam, Or a separate, electrical pump.

The only liquid I have ever found in any servo (booster) is brake fluid from a leaking master cylinder.
If the vacuum is low/absent, due to a faulty cam driven vacuum pump, and crankcase pressure rises, along with a faulty one-way valve in the vacuum plumbing, it's possible the oil could be forced into the servo housing, and operating the brakes would help it happen as the servo could act as a pump itself and draw oil from the engine.

Found some diagrams:

Where is the brake booster vacuum line on the 89 toyota camry?

Booster line will attach to back side (firewall side ) of booster chamber.

Should find a metal elbow coming out of the booster chamber that the vacuum line will slip over.

When you look at the booster chamber from the front, the location of the line should be at approx. 9 o'clock (as if looking at a clock dial)

My 2001 accent (automatic) sputters and stalls, some times just sitting sometimes during braking, once while driving. No Engine light or codes. Changed plugs, wires, PCV, Oil, oil filter, air and fuel...

if the pump pressure is within the specifications ( 45-65 psi) it will sat in those specification driving or stationary
a vacuum brake booster will cause the problems if it has a diaphragm leak when the brakes are activated but will not show as a code
vacuum leaks from vent controls , transmission actuator lines or unit will also cause the problem and again will not show as a code

Most likely your vacumn power brake booster has failed. It is not rebuildable. You will need to buy a new one.
