Likewise, what are primary brakes?
A primary brake valve controls communication offluid pressure to the primary brake piston.
Similarly, does the long or short brake shoe go in front? No the primary aka front shoe is always theshort one or the one with the least amount of frictionmaterial. The secondary or rear shoe always has the mostfriction material. No, NOT always. Non-servo brakes, likethe old Ford LockHeeds, have the longer primary shoelining towards the front.
Beside above, what is the leading brake shoe?
The term "leading/trailing" means thatonly one shoe is "leading", moving into the rotationof the drum and thus exhibiting a self-servo (or self-applying)effect. The leading shoe is "dragged" into the frictionsurface of the drum and thus achieving greater brakingforce.
What are the 2 types of drum brakes?
There are three types of drum brakes depending onhow the brake shoes are pressed on to the drums;leading/trailing shoe type, twin leading shoe typeand duo-servo type.
