1988 BMW 735 hydro boost problem
Brakes problem
1988 BMW 735 6 cyl Two Wheel Drive Automatic 80000 miles
First let me say this,I don't own a BMW 735i,But what I have is a 1971 Rolls royce that I installed a 1988 BMW hydroboost brake system on,The problem I'm having is the pressure is getting so high in the feed line that I'm burning up pumps,I have manual brakes,but not power brakes,the Power steering works until you apply the brakes then you lose power assist,I need a diagram of the original system for a BMW 735i,Everything I'm using came from a salvage yard,but I removed it and made a note of the hookup before I took it off the car.I did this because the original Rolls Royce system was destroyed,and the cost to repair was rediculous

Nevermind guys,I figured it out,The BMW pump doesn't make enough pressure to make the conversion work,I used a GM pump,now we're good.
