I installed new SS braided brake lines in front and my dash brake light stays on. I disconnected the wires to the proportioning valve and it's off now. Yes, I bled the front brakes after installing the new lines. I didn't re-blead the rear
Will the smaller diameter brake lines cause the brake light to stay on all the time? or do I need to check for air in the lines or a leaky wheel cylinder in the rear. I guess it could be coincidental that a wheel cylinder started leaking right after installing new front brake lines

The proportioning valve piston inside may be stuck to where it moved when your line leaked originally. It may not have returned to the original position once you replaced the line, so that may be why the light stays on now.
It's a two person process. What you need to do is to have one person crack a bleeder on the rear. Then with the key(brake light) on, you SLOWLY depress the brake pedal. Keep applying pressure until you feel a "pop" in the brake pedal. The light should go out. Stop and have your friend close the bleeder. Slowly ease the pedal back up. If after applying heavy pressure to the pedal the light doesn"t pop, close the rear bleeder, release the pedal and repeat the process with the front. NOTE, some times the pedal will "pop" and the shuttle valve will go the other way(the light will flash off, then be on again). If this happens, go to the opposite bleeder(front or rear) and repeat the process. Don't forget to recheck your fluid level.
