    Yesteray I bled the brakes on my '95 4Runner. Now the Brake Warning Light on the dash will not go off.
    The brakes feel strong, didn't disconnect any wires, don't believe I got any air in the lines.

    Any ideas?

    If I did allow some air in the lines would this cause the light to stay on?

    Check the level in the master cylinder reservoir.

    There are only 2 conditions that will cause that light to turn on: the e-brake is on, or the fluid is low in the MC.

    Thanks, I got it figured out.
    I checked both the e-brake and resevoir yesterday but apparenly did not check the resevoir well enough.
    I put a volt meter on the switch and found it was closed.

    Had to slip a thin wire down in the resevoir and un-stick the float (?)
    Also beat on the resevoir a bit more aggressavly (that's probably what did it)

    I supose the float stuck in the down position when I drained it before bleeding the brakes.

    Some little things just drive me NUTS!

    What does it mean if every now and then for a couple seconds the break warning light and check battery light flash together? This only happens every now and then.

    Alt brushes probably. I just got a new set for $6.

    Yes, this means your alternator is giving you warning signs of it's impending demise. Most of the time it's just the brushes, a very cheap fix, not very hard. The hardest part is getting it out of the truck. I'm sure there's a writeup on the web somewhere, look on 4crawler.com.

    Far too many expensive Toyota alternators and starters are replaced when they are actually easy easy to repair.

    I recently replaced the alternator a year and a half ago. So hopefully it is the brushes. I'll change them next time I'm feeling motivated. Thanks
