1997 Chevrolet Truck Repair Question
1997 Chevy Astro AWD Brake Problem
Maybe a bad booster or power steering pump.
But first check the steering part. Is the Serpentine belt tight? not slipping?
Will need to check pressure in the ps system if not belt problem is noticed.
Check the power brake booster inlet hose. There was a problem with them regarding noise when turning or braking. There is a revised pn 15094588 from the dealer.
