Or, the fluid WILL go through under pressure, but then when you
release the brake it will not flow BACK and you end up with your
brakes clamped on.



Don't forget vacuum hoses!  Many a slow-to-shut-off diesel engine,
dysfunctional door lock, or rough-idling gasser has been cured by their
replacement.

Re: [MBZ] old rubber (was rear exhaust hanger question)

Folks, its pretty well established that if you want all those parts of your 
car that relies on the flexibility of rubber (bushings, exhaust hangers, 
brake hoses, etc), that after about ten years, you should consider replacing 
them - at least the ones that are hard, cracked, swelled, or just out of 
shape.  Besides exhaust hangers that stretch and break, brake hoses have 
been known to swell and actually close up so that fluid can't get through to 
do what needs to be done!
Kind of like Dr. Booths admonition about fuses - change them out or be 
prepared to chase problems at inopportune times.

Yeah, mine went away recently too. Desert living has most things dried out
on that vehicle. I figured the fat rubber hangers were cheap and I must
remember to order them when I put in my glow plug order.

Meantime, I have two white zip ties on each hanger. That's class!

Upward travel is normally limited by a rubber bumper on the chassis
above the muffler, there should be a boss or something on the muffler
that bumps into it.  The improved 'donuts' have chain or something
inside the rubber so they don't stretch out.
