[Vwdiesel] Not Deisel, just brake bleeding hell on a VW bug question

[mark shepherd]

Bryan,
I see on the 'KATE' that some master cylinder's had a pressurising valve 
situated above one of the line outlets. Could it be that this is faulty 
somehow? The rest of the circuits are so simple as to be bullet proof, no 
regulator, just two tee'd  circuits! This thing just looks like a bolt on 
the diagram...

Regards
Mark

question



Hi all, I work on this ladies 72 super beetle from time to time, 95% rust 
free,
like working on history because so much of the car is still good.
anyway, I have a 20 hour brake story, what am I doing wrong.

starts out with soft to no brakes, OK, I can fix that for you.
I have a mighty vac.
It is not like the peddle will pump up, it just had little braking.
Tried to vac. some fluid out of the lines, got very little and no air.
ordered new master as this one was orig.
* Super beetle master cyl. is different, did not know that.

Dropped spacer sleeve into the abiss in the body, 1 hour tired to get it,
removed peddle assm. 2 hours later I had cut a new one from similar pipe 
stock.

Put new master in, did not bench bleed it.

nothing, could get very little suction with my might vac. to get good flow 
of
fluid from brake res. with fresh fluid in it.
tried pumping, nothing, no peddle would come up even after pumping 20-30 
times.

**************
I did press ALL THE WAY DOWN at times, maybe I blew it out here as you are 
Never
supposed to press it all the way?
**************

Took master off again to bench press after finding this great web sight. Rob 
and
Dave's Aircooled sight http://www.vw-resource.com/

I pumped it in a can of brake fluid and left it sit for 3 days while I was 
away
on a vw weekend.
came home, put it back in on Monday night, nothing, no change.
I would get just enough pressure to stop the wheels from spinning but still
would get little flow with mighty vac and I would things were looking better 
in
the back, as soon as I would open the front Rt. side, nothing, could no 
longer
get enough to stop the wheels from spinning.

Then went back to old fashion way, tried and true.
My wife would pump the brake 7-10 times, hold it in, I would open the 
bleeder to
hose and clear bottle 1/2 full of fluid. Close it, she lets up on the peddle
and pumps again. OK on the back, when I get up front, nothing, I lose all
ground on getting any peddle pressure.

So, back to square 1.
Master cyl is out.
I rent a brake pressure bleeder from Advance Auto Parts for FREE. It works 
as a
might vac OR you can fill the container on it and PUSH the fluid into the 
system
with like 10psi, it even has a gauge. So, I do this to each circuit, each 
wheel
and I have a good steam of clean fluid coming out of each bleeder, 1 by 1.

Today I will get a Replacement super beetle master, but TRW brand, not the 
KMM
brand I got before.
I Will bench bleed the new master cyl. out of the box before putting it on 
the
car, yes.

Any suggestions before I pull the trigger. I can't charge her for more then
like 6 hours of this ordeal.

AHHHHHHHHHHHHHHH
