Subject:      Help! Brake bleeding and Brake pressure regulator
Content-Type: text/plain; charset="us-ascii"; format=flowed

I'm attempting to bleed my brakes, and I'm getting no fluid, or very
little, coming out of the front calipers.

Here's the short version of the events.  Replaced Master cylinder.  Broke
off a bleeder on one of the rear cylinders, so the project stalled.  I went
out of town, etc, about 3 weeks pass.  Anyway, put in the replacement rear
wheel cylinder, and start to bleed again.  rear wheels bleeding fine.  At
one point I was getting fluid out of LF, but I don't think the RF ever was
giving me much.  Now I pump the pedal and then hold it to the floor, open
the bleeder and get a very slow minimal flow of fluid.  The caliper is
actually loose like there is no pressure in it pushing on the piston.  I
suppose it could be seized but I don't think so since it is only  a year or
2 old.  And the LF is doing the same thing now.

Bentley talks about pushing the lever on the brake pressure regulator
toward the rear axe while bleeding.  I think that instruction is from
another car, since there is no lever on the brake pressure
regulator.  There is  a procedure to test the Brake Pressure regulator,
that involves removing it from the body and tilting it forward.  Should I
have to do that to bleed the brakes?  I could find no hydraulic schematic
in the Bentley, but assume this is a dual diagonal braking system.

Thanks for any help.
