Brakes problem
1994 Chevy Astro 6 cyl Two Wheel Drive Automatic 106000 miles

Have recently replaced all suspension wear parts + shock adsorbers, brake pads and shoes, milled the roters. Problem: At slow speeds with hard braking the ABS disengages the front brakes and only the rear brakes are working to stop the vehicle. Computer diagnostic shows many electrical deficiencies which are currently being reviewed by the local automotive experts. All sensors are working and electrical connectivity is correct and working. The ABS dash light is not working. The situation is very dangerous and I do a lot of driving in the vehicle. The vehicle is maintained in excellent condition. Any suggestions on how to correct the ABS problem?

OK, First off the anti-lock brake system keeps the brakes from locking up like older model cars. If you front brake are not assisting with braking it could possibly be the Proportiioning Vavle
