I have a 2001 Malibu with ABS. From time to time, after the car has been parked for awhile. When I start it, and put it in gear. I'll find that the front brakes are locked up tight. After a few tries of putting it in park, and then back in drive, and giving it a little gas to force it to move, the brakes will eventually unlock. I think one of the calipers may be locking up. I would like to try bleeding the front brakes. But they are ABS, and according to the service manual they have an automatic bleeding system. Do I access that system through a regular trouble code scanner? or, Can I gravity bleed them? Also, is there any way to test the calipers when they are not locked to see if they are bad, or going bad? Would the ABS light come on in the instrument cluster if I had a bad caliper? Any ideas????
