Zero Break Pressure & DSC Warning Light

[schmidtp]

Good Afternoon,

Trying to diagnose the issue I am having on my 08 135. I have no break pressure and no fluid coming out of the rear driver side. After I pump the brakes over a few times I get "DSC Malfunction" warning.

Any insight on if this is an electrical or mechanical issue? Does the speed sensor control ABS/Brakes?

Thanks,
Patrick

If no fluid coming out of one caliper only, first look for a collapsed brake hoses. You have one at the caliper and at chassis to subframe. Next is the ABS/DSC hydraulic unit.
