[Spits] brake bleeding help

[Dennis Reese]

After installing new brakes front and rear I've been a bit frustrated bleeding
the system. The rear brakes seem to be OK but  can't seem to get much more
than air out of the front (new calipers, rotors, and hoses). Here's my
question: If the PDWA shuttle isn't centered does that mean that the circuit
is blocked and therefore won't allow brake fluid through? Also, the brake
light is on but not the oil light and doing the reset per the manual doesn't
seem to have any effect. Brake light stays on.

Any thoughts? Thanks in advance for the usual great advice.
