i work in a heavy duty brake distributor and this happens more than you realize.The main problem is that p/s fluid is petroleum based,and causes all the rubber parts in the brake system to swell.think about that for a moment,master cyl,hoses,calipers,abs components,wheel cylinders all HAVE TO BE REBUILT OR REPLACED!metal lines must also be flushed with clean brake fluid.if not comepletely removed,the p/s fluid WILL cause complete brake hydraulic failure,not a pleasent time in a motor home,whose brakes are usually marginal to begin with.
