Brakes problem
1989 BMW 735 6 cyl Two Wheel Drive Automatic

i have a 89 bmw 735il, left front caliper froze; I replaced the caliper and the brake hose and attempted to bleed them, no fluid came out the bleeder screw after numberous try's; I then checked the brake proporation valve and found no fluid was being sent through the side marked lv going to the left caliper: and also checked the other 3 valves they had a good steady stream of fluid coming out of them, what is the next course of action to take to get the left front caliper working and getting the brake fluid to it. Thanks

Do you
have the same problem?

The proportioning valve you speak of is called the anti-lock unit and it might require replacement. A salvage yard is the place to get the part you need, try Autobahn @ (619)444-2290 John or Sean can ship it to you UPS
