Vectra B

 

Brake Master Cylinder  

All Vectra-B vehicles are equipped with a tandem brake master cylinder.  

Two different types of brake master cylinder are used. For engine versions with traction control  
(X 20 XEV and X 25 XE), a brake master cylinder with two central valves is used. The other engine versions have a brake master cylinder with one central valve.  

Notice: 

The two versions are not interchangeable.
