Mercedes Benz C-Class (W204) 2007 - 2014 Training Manual: Brake System

Service brakes

The brake system for the sedan in the new C-Class with the hydraulic dualcircuit brake and the division into two brake circuits for front and rear axle largely corresponds to the previous version.

All versions are equipped with floating caliper brakes at the front and rear.

Service information:

  • The brake lining wear contacts are located at the right front and right rear wheel brakes.
  • After the entire ESP assembly or the ESP control unit has been replaced, the "initial startup routine" must be carried out using DAS.
  • If two or more lines were detached from the ESP hydraulic unit, then a subsequent "check for wrong connections" must be performed using DAS.
  • The "initial startup routine" must be carried out using DAS after the "yaw rate, lateral and longitudinal acceleration sensor" component has been replaced.
  • When bleeding the brake system, the brake pedal must be operated during the entire procedure (pumping).

    The bleed screw can remain open during this time.

  • When changing the brake fluid, "pumping" is not necessary.
