This article will introduce you to brakes and the components that are involved in a hydraulic brake system. We will try to break down the brake system in to its proper categories so that you can understand them better and apply that knowledge. | This article will introduce you to brakes and the components that are involved in a hydraulic brake system.

On them, the bottom of the shoes are solidly held against a pivot point, and only the tops of the shoes expand out to contact the drum. This design has less braking ability than a duo-servo type brake because only one shoe has a self-energizing effect. In this setup, the front (leading) shoe may be the same as the rear (trailing) shoe as far as the amount of friction material covering the steel backing shoe, but the material may be thicker on the front (self-energizing) shoe. In other cases the front shoe will be smaller like the duo-servo type. |

| + | There has been years of confusion on the issue of which position the longer lining shoe goes in. The reason for the confusion is the Willys Overland company and it's successive owners.

| + | Old Willys vehicles are the major exception to this rule. All old Willys (Jeep) vehicles - CJ-2A, CJ-3A, DJ-3A, M-38, CJ-3B, early CJ-5, M38-A1, Wagon, Truck, Forward Control call for the longer shoe to be placed to the front. Any factory manual will confirm this. Don't trust aftermarket manuals, they may tell you to follow the convention that the rest of the automotive world followed for decades. | ||
