Cars without ASR traction control system
The control electronic device of Mercedes is necessary for removal of air from the brake system of the car with ASR. The device is connected to the diagnostic plug on the right in a motor compartment. When pressing a key air from ASR system automatically is removed.
After each repair of brakes at which the brake system opened air which surely has to be removed from there can get into pressure head pipelines. A sign of availability of air in pipelines of system is lowering of a pedal of brakes when pressing it a leg without notable resistance. In this case it is necessary to eliminate leakage and to remove air from system.
Air is given by pressing a brake pedal, at the same time still the assistant is necessary. If it is necessary to remove air from all brake system, then it should be deleted from each brake cylinder separately. At regular replacement of brake fluid within maintenance it is necessary to delete air from all four brake cylinders that it did not get into the brake system.
Sequence of removal of air:
1. Right back support.
2. Left back support.
3. Forward right support.
4. Forward left support.
If the support was replaced or under repair, as a rule, enough removal of air from the corresponding cylinder. If repair was made at an empty tank for brake fluid, then removal of air from all brake system is necessary.
Before removal of air unscrew a cover of a tank of brake fluid and fill in brake fluid to the mark "max".
During removal of air watch a tank of brake fluid. Level of brake fluid should not fall too low, otherwise through a tank air will be soaked up. Always add only fresh brake fluid!
