I recently bought a 1993 Grand Am for my daughter to drive. It is in good shape with one exception. I replaced the front brake pads, right rotor and right caliper which was locked up. The ABS light is on and when I went to bleed the brakes, there is no brake fluid getting to the right caliper. There are no external brake fluid leaks. I am thinking there is a valve stuck closed in the ABS hydraulic unit. Any help would be appreciated. Also, the brake line is clear. I disconnected it from both ends and blew air through it.
