Product Title
Mercedes-Benz W211 SBC Brake Master Cylinder Unit A2114300302 - Used Original Parts
Diagnosis and Common Symptoms
From a workshop perspective, the Sensotronic Brake Control (SBC) system is a common point of failure on the W211 and R230 platforms. The primary indicator is the "BRAKE" warning message on the instrument cluster, which can appear in either white or, more critically, red.
Diagnostic scanning will typically reveal fault codes related to the unit's internal service life. The most prevalent code is C249F - OPERATING TIME OF COMPONENT A7/3 IS EXCEEDED. This indicates the internal pump has reached its pre-programmed operational limit set by the manufacturer for safety. Other symptoms include an unusually hard brake pedal, the hydraulic pump running excessively, or a complete loss of braking assistance, reverting to a failsafe hydraulic mode.
Introduction
This is a Genuine Mercedes-Benz SBC hydraulic unit, meticulously removed from a donor vehicle. Each unit undergoes a bench test to verify pump operation and pressure accumulation before being listed. Opting for a genuine used component is a cost-effective, reliable solution to restore your vehicle's complex braking system without compromising on the original engineering and safety standards.
