What is a servo on a car?
Answers:
It's part of "power assisted" steering or braking.
The rising stroke of the pistons causes a vacuum in the engine. When you turn the wheel or push down the brake pedal, the servo uses the vacuum to increase the force on the steering box or brake cylinders so you need less effort.
a servo is under the bonnet and uses the braking force from the brake pedal and multiplies it to make enough force to apply the brake pads and shoes to the brake discs and hubs.
its what controls the pressure of fluid in your brake system
It is a device that multiples the effort you exert on the brake pedal using the vacuum from your engine to do so.Also used in many other ways in a vechicle but i think it was the braking system you were refering to.Regards Mike
hi, the servo on a car is for the brakes. It uses the vacuum force created by the engine to reduce the amount of pedal power needed.
It is therefor connected to the "inlet manifold" which is generally cast aluminium and leads from the air cleaner to the engine.
Happy to simplify further if required.
In its early days it was something to remark on "servo assisted brakes" weren't rare but not all cars had them by any means. Rather like a heated rear screen.
