I need help. I can't get my 1996 Cadillac Deville Concours break leak fixed due to the fact they told me it's a dealer only part that the break line goes into, and it's no longer made. I don't even know the name of said part. Any info would be greatly helpful.
I have a DTS 2006. The other day I took it to pump some air in the tires in the gas station. After I’m done there was no pressure in break pedal. It sinks all the way down. Also it gives me these messages:
