99 gmc 3500, hydro boost, all 4 brakes lock up

Recommended Posts

I've got a customer that has a 99 GMC K3500, 5.7, auto, with the hydro boost brake booster. His brakes are extremely touchy and lockup with very little pedal pressure. Brakes are almost new on all 4 corners. Before I replace the hydro boost unit just want to see if anything else could cause this problem. Power steering works fine, if anything it is also a bit sensitive.
