Until about a week ago, no problems. I had a complete brake job last year.
I noticed recently that the brakes were taking longer to stop. I just figured I wore the pads out again, I drive a lot and am somewhat led footed. But going home yesterday, the pedal on the truck would go most of the way to the floor and was very spongy. The truck would stop but the harder I pushed the pedal, it didn't seem to change how fast I was stopping. Kind of like stopping a ship at sea. On the way home, the ABS and Brake light both came on. I stopped and found that the master cylinder resovoir was almost empty.
I stopped at a local shop and had it checked expecting to find that I had a leaking caliper at 98K miles. The mechanic looked at it and said he didn't see any leaks on the front or back and that I had 70% wear left on all of my pads. He felt that the last people who did my brake job might have bled the brakes but not refilled the tank.
When I left, the ABS light and brake light were still on but he said that the ABS unit needed a few miles to get filled back up and that it should go off. The brakes seemed better but still not normal. I drove it to work today and the lights are still on after about 40 miles. Braking is back to being terrible.
Any ideas? A leak he didn't notice? A bad ABS unit?
Thanks, Michael
