MASTERVAC and MASTER-CYLINDER
Ref: ANA-MMC

This pedagogic unit allows a complete study of the braking assistance device (mastervac) and of the master-cylinder.
It is specially appropriated for functional and structural analyze lessons, mechanics, technology and exercises.
The student is going to acquire the following competences :
- Locate the components in the vehicle
- Locate and identify the different components of a mastervac and a master-cylinder.
FOR THE MASTERVAC :
- D’analyser le fonctionnement d’un mastervac du point de vue qualitatif (amplification, point de saturation, régulation) mais aussi quantitatif (lois d’assistance, efforts et pressions en jeu).
- D’analyser les dysfonctionnements du mastervac (manque d’assistance, défaut interne, clapet HS).
For the MASTER-CYLINDER
- Analyze the internal working stages of the master-cylinder (rise in pressuring according to the brake fixing tests).
- Quantify the races, pressure and efforts concerned.
- Analyze the failures due to a hydraulic leakage (partial or total).
