Re: [MBZ] Stuck calipers

[OK Don via Mercedes]

Perhaps with the caliper still in/near the car, the brake line is still
attached, thus blocking that hole and allowing the bleeder hole connection
to build the pressure.

Re: [MBZ] Stuck calipers

[Allan Streib via Mercedes]

I mean, if you're pumping grease into the bleed fitting, don't you need
to have the hydraulic line fitting blocked also? Otherwise I'd think the
grease/fluid will take the path of least resistance and come out there
rather than pushing out the piston.

Re: [MBZ] Stuck calipers

 Shouldn't have to. Assuming the caliper is full of fluid you'd be introducing 
a fairly small amount of grease.
A year or two ago I used the grease gun to pop a dent out of a Coleman lantern 
fount. I filled the fount with ATF first. I found there was a little grease in 
the adapter I made but none in the fount itself.

Re: [MBZ] Stuck calipers

[Mitch Haley via Mercedes]

I used to hit the hydraulic line fitting with a rubber tipped air nozzle 
after stuffing shop rags in front of the piston.

But with multi piston calipers that only gets the easiest piston out.
Sometimes I'd get the easy piston done, put it back together, put a 
clamp on it and try to blow the stuck piston out but half the time it 
would be stuck too firmly to remove with air.

Hey Curley,
I had a similar problem.  I read somewhere I could hook up a chassis 
grease pump thingie into the bleed valve hole.   I found it screwed in 
easily and a few pumps of the grease pump handle and the puck slowly 
walked out.  I had to clean the small amount of grease that remained but 
it was less trouble than I thought it would be.


Hydraulic action is a powerful force!

Let me know how this works for you, I used it on 2 or 3 calipers.

Compressed air is typically less than 125 PSI.  Pretty wimpy
compared to common brake pressure of 400-500 PSI or hard braking
that can generate over 1000 PSI.  So if the piston was stuck
enough to not move with brake line pressure, it sure won't move
with typical shop compressed air.

> A could throw them out, but if I can fix em, I can use em some  day.

When I came upon this situation at the end of my conversion of our
'82 240D to a 240D/3.0, I opted to buy new calipers and, since we were
going to be moving, threw the old ones away.

I did not know at that time about Kroil. Have you tried Kroil and
compressed air?

Better would be Kroil and brake fluid by connecting them to the car's
hydraulic line or to a pressure pack (which might be a grease gun -- fill
the caliper with brake fluid, put a zerk on the supply hole, and pump
grease into the caliper, which can get up to 10,000 psi.).

that might get one side out, but how do you get the other side out.   
I've tried 100+psi air.

Hook one onto a brake line, stomp on the brake pedal, the puck will shoot
out.
