Servos, Brake Pumps, & Abs Modules
Guide To Diagnostics & Repairs - Car Mechanic Simulator 2015
Depending on the vehicle, it may have one or all of these systems. For example the Rex does have the ABS Pump, ABS Module and a Brake Servo. If a vehicle has ABS it always has both of the ABS parts, and probably the Servo as well.
The one vehicle that does stand out as different is the Maluch. It only has the Brake Pump, which is completely different in appearance from the others. It is also located in a different place. It can partly be seen from the trunk (which is at the front of the car), but can only be accessed from beneath the vehicle.
