Remote Brake Servo

[VmaxTriker]

Hi Chaps

Hi could some kind soul please explain in simple terms what a remote brake servo actually does and HOW does it do it.

I gather it assists with the braking but how?

Does it need a power supply?

Is there a rule concerning bore sizes, I take it not every remote servo is the same and certain servos will only work with certain bore sizes.

ok seems it needs to be connected to the inlet manifold to create a vacuum etc..

Oh well nevermind... onto next idea.

What's the issue with fitting one.
 
They work by removing air and creating vaccuum behind what is basically another master cylinder. When you touch the brake pedal a valve is opened in the servo to allow air to rush in. The result is assistance to the braking effort.

You can use a vaccuum pump as used on diesel engines to create the servo vaccuum.

Just seemed complicated... I guess its quite simple once its set up correctly.

I take it the vacuum pump has a continous power supply like a fuel pump?

[ByzMax]

Vaccuum Pumps are electric yes. (mostly) some are fitted to other parts like the back of the alternator.

There should be some points on the inlet manifold to use as a take off for the servo without a pump.

The are very simple things to fit

ok mate thx for the info its appreciated, il have a look and see if the vmax engine has anything suitable already in place.

use one of the vacuum spigots on the inlet manifolds, or if your fuel tank has a vacuum tap put a "T" piece in and branch off that pipe.
