Power Steering Fluid Leaque

[gune562]

Hello All,
I am new to the forum and this is my first post. I have a 1985 BMW 635 CSI and this passed weekend I finally brought her out of storage. When I tried to apply the brakes the car wouldn’t brake. So I removed the brake master cylinder and to my suspicion the piston was not resetting.

I made the mistake of pumping the brake while the brake master cylinder was disconnected and a connecting shaft along with a ton of power steering fluid shot out. When I re-coupled the master cylinder with the power steering housing that is connected to the fire wall, I was not sure of the orientation of the connecting shaft as it is tapered at one end and has a 90 degree angle on the other end. As a result, I have a large leak where the brake master cylinder connects to the power steering housing next to the firewall.

Does anyone have any suggestions at to why I am getting a leak? Is there a seal that might have shot out when I applied the brake pedal? Thank you.,
Sal

I think you are in a bit of a pickle and need to purchase some parts.

Thanks Jose,
This was exaclty the problem. When I pulled out the old seal, the O.D. was not even round. I simply replaced the seal and the fluid stopped leaking.

Which seal? The one around the shaft that shot out, or the one on the plastic cup shown in the link?

And did you figure out which way the shaft went in?
