Brakes problem
1994 Oldsmobile Achieva 6 cyl Front Wheel Drive Automatic

I had the 2 rear brake lines replaced with new wheel brake cylinders and pads , followed the proper bleed procedures for abs .I now have a left rear brake that continues the lock up under med. to heavy breaking.
my machanic thinks that when my rear line failed it jamed the abs system . is there a way to reset the abs proportioning valve. thank you

Try disconnecting the battery for about 5 minutes. However, I don't believe that is the problem. If you remove the drum, is everything still dry? Also, did you replace or cut the drums and properly adjust the rear brake shoes?
