2000 astro awd Brakes

lose hyd assist when making turn & braking at same time,feel this is safty issure to,turn into parking space and need to over come hyd. assist to stop van. very intermitten problem. HELP

This van uses hydro-boost for brake assist. It uses the power steering pump for the hydralic pressure to assist in braking. Check the belt tension, make sure it isn’t slipping.

I have seen the power steering pulley shaft break off on these Astros,weak design.

replaced pump twice, INTERMITTEN problem , never lose steering , only brakes
