Non-ABS 2000 Sport 5spd.
Ok, this problem is a little unusual. A week ago while driving, my brake warning light comes on. I come to a stop, the light goes out. Then a few miles down, it comes back on and has stayed on, aside from when I press the brake down firmly. That is to say, if I press them down 75% of the way, the brake warning light goes out.
I pulled the plug on the proportioning valve and the light goes out, so a problem in the fluid balance? No brake fluid has been lost over the past week and brakes feel the same as they always have. We have driven about 600 miles this past week.
I haven't had a chance to bleed them yet, but I don't know how I would have introduced air into the lines.
I will bleed the brakes this week, but any thoughts as to what else I might check?
