My '71 96 winter beater had some soft brakes the last month or so I drove it. I pulled the master and found it leaking, so got a rebuild kit. This weekend, I took it apart and things seemed pretty clean- no pitting of the bore. I carefully cleaned everything and rebuilt it and put it in the car. Driver's front bled fine. Went to the passenger front and no juice came out the bleed screw on the caliper. Took off the fitting at the master- no juice there either. Okay.
Took it apart again. This time I pulled the plastic reservoir off along with the rubber fittings and made sure the holes were clear (there are two for each, a small one and a bigger one). Put it all back together. Driver's side bleeds fine and nothing out the passenger side. Same as before.
Went to my parts stash and found two ATE brake master's. One pretty good and one pretty rusty. Took apart the good one, looking carefully to compare this one to the rebuilt one and it matches- all the seals, springs, washers, etc are correct. Cleaned out THIS one and rebuilt it, using the same rubber parts from the rebuild kit. Got the SAME RESULT.
Now I'm getting frustrated.
Took it apart again, went over it and over it, comparing it to the manual. Everything looks right. Put it back together. This time I filled it with fluid on the bench. I pressed the plunger a couple of times and got two streams of fluid shooting out. Put it in the car... you guessed it, driver's side bleeds fine, nothing from the passenger side. Again took off the fitting at the master, pushed the pedal and no juice comes out the master.
What gives? Any thoughts on why this could be with two different master cylinders? Note that the brake line connected to the passenger side is the one deepest into the master.
It's as if fluid doesn't drain down into that deeper end of the master, once it's on the car.
This ATE master has the little screw half way down the cylinder. In order to get the deeper piston out, you loosen the screw. Once assembled, you tighten it. Does it have anything to do with that?
My wife says she's had enough of me fooling with this- tired of me smelling of Castrol LMA and tired of "DOWN... UP...DOWN AGAIN...HOLD IT DOWN... UP...". Told me tonight "ask your Saab friends. They'll help you out!"
So what do you say? Anybody got advice? Or a good working late model ATE master????
