I have a 1997 Olds Cutlass.My husband replaced the brake pads, front and back, about three months ago. The ABS light has been on since, but we weren't overly worried about that. My car sits for a week at a time without being driven, and the last time I went to drive it, the red brake light was on and stayed on. He's bled the lines, checked the emergency brake switch to make sure it's not staying on, and checked the master cylinder. The brakes work fine, but I worry. What else can we check? I'm disabled and he's in construction, so no money to take to a shop. Help! Thanks.
