For the braking system of your Jeep to be effective on and off the road, especially if it is equipped with the drum brake system, your vehicle will need to have a number of functional parts, and these include the Jeep wheel cylinder. Other components of the drum brake system aside from the wheel cylinder include the backing plate, the brake shoes, the brake drum, the return springs, and the automatic or the self-adjusting system. The moment you apply the brakes in your Jeep, the brake fluid will be forced, under pressure, into the wheel cylinder, which will in turn push the brake shoes in contact with the machined surface on the inside of the drum. The moment the pressure is released, the return springs will pull the shoes back to the rest position. That is how the drum brake system basically works, with the wheel cylinder performing a very crucial role in the set-up. Typically, the wheel cylinder may consist of a cylinder that will have two pistons, one on each side. Each of these will have a rubber seal and a shaft that will effectively connect the piston with the brake shoe. You have to remember that the wheel cylinder may fail in the long run, and one of the problems that may be attributed to the part is leaking. You can confirm a leak on the cylinder if you notice fluid when the dust boot is peeled back, when the cylinder, linings and backing plate are wet, and when there is a drop in the level of fluid in the reservoir. These are tell-tale signs that your stock wheel cylinder is acting up and may need a fast replacement.
