Re: [MBZ] Master cylinder

2021-07-17 Thread Allan Streib via Mercedes
If you have a NAPA nearby I would get one there. You can look at it before you 
walk out, and if there are problems with it you will have someone local to deal 
with and a hassle-free return/exchange.

Autozone, Pep Boys, and others also warranty what they sell but they are a 
lower tier in terms of the quality of the parts and the 
knowledge/professionalism of the staff, at least in my experience.

Saving $10 over the expected lifetime of a master cylinder is meaningless, 
regardless of the age of the car.

FWIW I bought a Dorman manifold crossover for my '95 Crown Vic a while
back. It was good quality. Things change over time.

I think they’re different than the “regular” grommets, so be sure to check the

The washer fluid tank is a major PITA to replace. Ironic that they’re so 
brittle when they age, causing even a casual glance at one to shatter it. You 
know it’s bad when the dealer stocks them for a car that they stopped making 15 
years ago.

Re: [MBZ] Master cylinder

2021-01-05 Thread Max Dillon via Mercedes
How much is a new MC?

Last time I bled brakes, following a MC replacement in a hotel parking ramp, I 
bought 20 feet of clear hose (fish tank air line, about $10 from Walmart pet 
department) and then ran a line from right rear caliper bleed screw back up to 
MC reservoir.  Open bleed, pump the brakes until no more air bubbles, repeat at 
the other three calipers, done.  I think I also needed a small can of new brake 
fluid.

I tried everything else and got nowhere until I replaced the MC. It wasn’t a

Pedal does not go to the floor. Just too much travel. When I bled it this last 
time I basically ran a whole large bottle of fluid thru it. Some of the 
calipers took a while before I started seeing bubbles in the clear tube. After 
they quit I let it run for a while after before closing the bleeder.

Or brakes that won't release.  The OP's problem sounds like it's
not bled correctly.  Especially since he didn't touch the MC mechanically.

Always thought bad master cylinder was a slowly sinking pedal.

If pedal travel is too far, the pushrod on the pedal needs to be
adjusted?

Spongy or pedal to the floor is air in the lines. Guess that could also
be a bad wheel cylinder or caliper, leaking line, etc.

When you say lines do you mean at the master cylinder?
There is a line on either side of the sensor.
Cracking the lines there might re-center the pin.

Bleeding the brakes did not solve the problem. The light is still on.

Randy, I think Philip is on to something.  If you have your owner's manual 
there should be an explanation for that light, and I think it is a simple float 
sensor to warm of low brake fluid.  The same light may also indicate when the 
parking brake is applied, which may be a simple switch at the parking brake 
pedal mechanism: maybe that is the cause of your flickering light?

I assume (always dangerous to do that) that the 76 115 300D may be more 
like the 123 in any event as the earlier 115 models did not have the 
pressure imbalance sensor.


You are correct that there are two sensors - 1 for pressure imbalance 
and the other for low fluid.
They are wired together in the sense that the low level sensor has 2 
wires for it and the pressure sensor has one lead that appears to come 
on from the first. Like an oil pressure gauge, I assume (there it is 
again) that it grounds out when it puts the light on.
The bebuilt unit came with neither sensor. The level sensor is built 
into the resevoir and is not removable. I have not checked to see if it 
works. I could do so while bleeding the brakes as the level will no 
doubt go down. I am not pressure bleeding but just opening the wheel 
cylinder bleed screws while someone else steps on the pedal for me.
I believe the issue to be with the pressure sensor as unplugging the 
lead from it puts the light out.
It has a small white plastic pointer on it and I believe that the 
pointer will be moved one way or the other by the plunger in the body of 
the master cylinder when it is moved one way or the  other by the 
pressure from the main plunger.
One thought that comes to mind right now is that it might be in order to 
loosen it off enough to bleed it too just in case there is some air in 
there.

Will try that tonight.
If that does not work and it is still wonky after I bleed the brakes, I 
will remove it temporarily and test with a meter to see if it is 
grounded out all of the time.

Re: [MBZ] Master cylinder changing/bleeding

2007-11-07 Thread Rich Thomas
The reservoir actually has a round volume beneath the rear sensor, and a 
squarish volume beneath the front sensor, with what appear to be floats 
in them that come up to the vent caps (2 of these next to the sensors).  
From what I can see looking in the cap hole, they look like they are not 
connected to the main reservoir, but there might be some holes in there 
somewhere.  It does not look like there are two chambers with a notch 
(like on my other vehicles).  This is why I was wondering how to fill 
those chambers in there.

I did pump the pedal some and it was real squishy, so will have to get 
out in daylight in the morning and bleed them.  I have used the Mityvac 
to do that too, it works pretty well..All the hoses going here and there 
for bleeding and collecting are annoying as one always comes loose, or 
out of the collector bottle, or twists up on something else...

I was thinking to make a pressure bleeder, I have an old Nalgene bottle 
and some barb fittings and hose somewhere, use a bit of compressed air 
to push the fluid.  Maybe next time.

Removing and replacing the MC and hooking it all back up would have 
taken about 15 min except for that last brake line fitting that took a 
half hour to get lined up to catchhhh.

[EMAIL PROTECTED] wrote:
 Rich,
  
 You can fill both chambers by filling the area below the cap, when it  
 reaches a certain height, fluid will flow through the barrier notch into the  
 rear 
 chamber.  I understand you already have the MC installed on the  car,   You 
 can 
 bleed a new MC through the brake lines with the brake  pedal as the seals 
 will be running in freshly machined cylinders.  Or a  mitivac works well too. 
  
 The best is a pressure bleeder that pressurizes  your MC reservoir using a 
 special reservoir cap.
  
 My rebuild came with two plastic disposable hoses and you screwed each of  
 them into a discharge port.  Clamp the master cylinder in a vice, fill  it 
 with 
 brake fluid, and push the brake piston with a piece of broom  handle or such. 
  
  Then let it discharge back into the reservoir  until the bubbles stop.   
 Leave the fluid in the master cylinder  and leave the bleeder hoses installed 
 until you have the master cylinder  mounted.  Protect the area under the 
 master 
 cylinder from brake fluid as  some will run out when you install the 
 permanent 
 lines.  Brake fluid is a  mild paint remover so cover the fender too.

And if it doesn't remove the paint, even a small amount spilled onto the
paint and then quickly removed will cause the paint to crinkle like the
old crinkle finishes. Had that happen to our car. A new hood as the result
of a rear-ender fixed that problem.

Re: [MBZ] Master cylinder changing/bleeding

The cap opening shows both chambers on some, but I think on that one 
(sort of triangular dual tank?) you just fill up the front one until it 
overflows into the rear chamber.  Make SURE the rear chamber always has 
fluid in it, else you just pump air into the lines.

I use a MitiVac to bleed the brakes -- works great and once you have 
fluid in the lines, they will all gravity bleed just by opening the 
bleeder with a hose slipped over it.

So after  messing around to check the vacuum on the 79 TDs brakes, I 
finally figured  it must be the master cylinder (as someone suggested, 
but I needed to  check the vac anyway).  So I have the new one on and 
everything  hooked up, now to bleed it all.  How do I Make sure that all  
chambers are completely filled with brake fluid? as the manual says to  
do (but not how to do that).  There are two smaller chambers in the  
reservoir, under the switches, not sure how fluid gets into them --  
might it be through the vents on top?  Or how?  Or do they just  fill up 
on their own from the main part?




Rich,
 
You can fill both chambers by filling the area below the cap, when it  
reaches a certain height, fluid will flow through the barrier notch into the  
rear 
chamber.  I understand you already have the MC installed on the  car,   You can 
bleed a new MC through the brake lines with the brake  pedal as the seals 
will be running in freshly machined cylinders.  Or a  mitivac works well too.  
The best is a pressure bleeder that pressurizes  your MC reservoir using a 
special reservoir cap.
 
My rebuild came with two plastic disposable hoses and you screwed each of  
them into a discharge port.  Clamp the master cylinder in a vice, fill  it with 
brake fluid, and push the brake piston with a piece of broom  handle or such.  
 Then let it discharge back into the reservoir  until the bubbles stop.   
Leave the fluid in the master cylinder  and leave the bleeder hoses installed 
until you have the master cylinder  mounted.  Protect the area under the master 
cylinder from brake fluid as  some will run out when you install the permanent 
lines.  Brake fluid is a  mild paint remover so cover the fender too.
