most early bus and beetle guys cringe when i tell them how much some things 
cost on a bay. i.e. the mastercylinder. another one is type IV pistons and 
cylinders...ouch. oh, and beams.

Brian:  Just checked with Oak Hill Auto in Longview and they have a new German 
ATE for $145.  There phone # is 903-297-3496 if you want to give them a call.  
They can UPS it to you, but by the time you paid shipping the one at Rogers 
would probably be cheaper.

says they can't get one for my bus. A new one cost $200 at bus-boys.com and 
about 150 at roy rogers. guess i'll be going to roy rogers in the next month to 
get a new one.

        You don't have any time.Fix your brakes NOW! If you don't the fire will 
have been minor.If you don't have brake assist the mc should be around 40 bucks 
at your FLAPS.I just bought one for a bug for 30 bucks.    ----- Original

It sounds to me like you have a leak in
 the MC.  Fluid going past the piston (which it is not supposed to do) which 
means a new master cylinder.

Brian Denning <i_am_cool_fred@xxxxxxxxxxx> wrote:       ok, the mastercylinder 
has 3 lines coming out of it one that goes to the rear one for the left front 
and one for the right front. at the mastercylinder i bled all air out of 
it...there was lots in the line that went to the rear of the bus and some that 
went to the driverside front. so i bled all the air out at the MC then i went 
to the right rear. by i, i mean a friend of mine. we did the ol' tube in a 
bottle of fluid trick. got some small bubbles out of the right rear, next we 
went to the left rear, man oh man there were some
 bubbles after we pumped it two or three times. then we went to the right 
front, it took forever to get to fluid (keep in mind i have already bled 
everything 4 times before this point) then we went to the driverside front. got 
air.
 
pedal then worked but not impressive. so we decided to pressure bleed the 
system at this point pump, pump pump HOLD!!! right rear spit out air twice then 
solid fluid shot out like a water cannon. pump pump pump HOLD!!! left rear did 
the same. moved to the right front it took 5 tries to get the final air out of 
it. then we moved to the right side. fluid came out like an old man trying to 
pee, slow and it dribbled for a bit.  we did that for a bit and then all of the 
sudden the fluid shot out so strong it hit the  other side. tightened it up 
 
the brakes are great, they don't give way but there is still a slight problem, 
if i come on strong at first they work great. i even tested them and managed to 
get all four
 wheels to lock up, if i eas on them the pedal goes down about half way till it 
works, and if i just gently push it in it still goes to the floor.
 
what do ya'll think? mastercylinder needs replaced or still some air hidden 
somewhere? i am buying the appropriate tool from harbor freight this weekend 
and will try it again but i am leaning towards a mastercylinder. like a friend 
once told me "rebuilds only last so long"
