Dash Brake light stays on
#11
I remember years ago, I replaced all the brake lines and the master cyl on my truck and I couldn't get the brake light to turn off. I tried everything I could think of to get it to go out... It turned out to be the wife stepped on the parking brake a bit on accendent and that caused the light to turn on! I spent countless hours tapping the proportioning valve and bleeding the master cyl... Bled the wheel cyls and the front calipers at least 4 times! All because of the E-brake was down one click...
What can ya do!?!

Just found the following in my 97 Service manual;
BLEEDING BRAKE SYSTEM
ABS BLEEDING PROCEDURE
NOTE: Bleeding ABS system requires the use of Tech 1 scan tool. An
assistant is required when performing bleeding procedures.
1) Raise and support vehicle. Begin bleeding at right rear
wheel. Install a clear plastic hose to bleed screw. Immerse other end
of hose in container that is partially filled with clean brake fluid.
2) Open bleed screw 1/2 to 1 full turn. Have assistant slowly
depress brake pedal until it reaches full travel. Hold pedal until
bleed screw is closed. Release brake pedal and wait 10-15 seconds.
Repeat until clean bubble-free brake fluid is present at wheel bleed
screw.
3) Check master cylinder fluid level every 4-6 strokes of
brake pedal to avoid running system dry. Repeat steps 2) and 3) on
left rear, then right front, then left front. After bleeding all 4
wheels, go to next step.
4) Using scan tool in FUNCTION TEST, run FUNCTION TEST 4
times consecutively while applying the brake pedal firmly. Release
brake pedal between each test.
5) Rebleed all 4 wheels using steps 2) and 3) to remove
remaining air from brake system. Ensure brake pedal feel is
appropriate before attempting to drive vehicle. Rebleed as many times
as necessary to obtain appropriate pedal feel.
