Suspect brake fluid leaking

[t-tan]

Dear BMW 5 series community and all honorable sifus,My e60 babe is showing something strange lately. I notice the brake fluid is almost empty when I checked it in the morning before I start the car, then it showed a small quantity at the low end of the dip stick when I check it again after a drive. Funny thing is I just changed the fluid 5/6k km ago and it's not due for another change till 2/2014 (following the recommended schedule). The brake also makes noise during the morning start after not driven for a few days. Can somebody here tell me if this sort of thing happened before? Could it be some leaking somewhere in the tube/pipe/hose or something's broken.... It's a 2010 CKD model.Thanks a lot for your advice and sharing.Cheers,Tommy

Tommy,

If I were you, I would immediately send my car to the workshop for a thorough brake system inspection. Brake fluid is highly corrosive and your brakes can fail any moment while on the road.

That is also why I changed to stainless steel brake hose.. I think in the market there are Goodridge and Pro-RS brand to consider.
