There is something screaming coming from the mastercylinder. Brake, ABS, VSC, VSC OFF, and buzzer are on. Was wondering if anyone ran into this problem before? I'm wondering if its just the hydrolic brake booster pump or its the whole mastercylinder assembly with pump and acumulator. I pulled out the code and the code came out as c1246, c1252, c1256 . Thanks in advance to anyone that can help.

Another question is are the abs, master cylinder unit the same from 1998 - 2005? I guess I mean gs300, gs400 and gs 430!?
