dual brake booster ????

Could someone please explain the advantage of a dual booster over a single?

 

I'm ***uming you mean the power booster, not the dual resivoir master cylinder.

I believe the dual diaphragm boosters hold a higher pressure usually required in 4wheel disc brake applications. I've also heard they work better with engines that have lower engine va***e. I also know part of the advantage is they can get the stopping power of a larger single diaphragm unit with a smaller diameter package.

hope that helps.

 

Same force in a smaller diameter.

 

The advantage is more diaphragm area in square inches that reacts to incoming atmospheric pressure, resulting in higher levels and more linear pedal ***ist.
