    Last fall I had to replace my rear brakes, due to one shoe having its brake lining brake off. ABS light came on after replacement, I bled the rear brakes and the problem was solved. This fall my rear brake line rusted out, causing loss of brake fluid. Replaced line, filled master cylinder and vacuum bled the rear brakes. I'm now having an intermittent problem with my ABS light. Some times the ABS light comes on when I press on the brake pedal, press on the pedal a second time and it turns off. Sometimes I need to press the pedal twice but the ABS light does go of and stay off.

    I'm at a loss, the brakes seem to be working fine. What am I missing? I use the truck mainly for plowing and if I need to haul something. Other than that it is just a back up vehicle.

    Thanks in advance for your help and suggestions
