97 CCLB, I haven't done any brake work on it, only thing I've done is top off the brake fluid to see if that would shut off the brake warning light. That light turned on and off periodically as I was driving, sometimes it would just flicker like it was trying to shut off. Most recently, I ended up having to drive through a pasture area that was quite muddy. Needless to say I had to try the 4X4 to get around. As I was leaving the ABS light came on and hasn't shut off since. Is there mud somewhere that could be causing this and what causes the brake warning light to come on like that? All the help is appreciated.
