Why Repairing Hydraulic Brakes Is More Complicated Than Disc Or Drum Brakes


Most people who take the time to watch an instructional video on replacing or repairing disc or drum brakes tend to think that repairing hydraulic brakes would not be that difficult either. Nothing could be further from the truth! Hydraulic brakes are far more complicated, and you will need to take this vehicle to a brake repair shop. Here is why.

Disc Brakes Have Stacked Components, but Not Hydraulic Cylinders

Imagine taking some toy gears or blocks and stacking them on top of themselves. They fit together and stay in place until some force (like your hand!) knocks them apart. That is exactly what disc brakes are like. Their components stack on top of each other, and then they are bolted together and bolted to the axle. Hydraulic brakes, on the other hand, are nowhere near as simple. Hydraulic brakes require hydraulic cylinders to apply pressure to the wheels to stop, and they have several more components.

The Fluids, Hoses, and Lubrications Are Different Too

Hydraulic brakes have hoses and lubrication that pass through the hoses to the brakes to help them tighten up and grip properly without wearing out. When the hoses split or crack, the lubrication fluids are leaking, and the brakes cannot grip right, you have a very big braking problem. If you were driving a vehicle with disc or drum brakes, these fluids and components are not that big of a deal. (They are still important, but less serious.) The car or truck can still move because no hoses or lubrication have to be present for the brakes to work.

Construction and Repair of Hydraulic Brakes Is More Vertical

Because of the sheer size of vehicles that utilize hydraulic brakes, it becomes necessary to construct a braking system that is more vertical than horizontal. You are sitting in the cab of the truck, and the brake pedals are under your feet. The brake pedals have to press down on calipers and then onto the wheels themselves. In between your foot and the next component of your braking system are those hydraulic cylinders. When you step on the brake, the brake activates the cylinder, compressing air within the cylinder, which in turn applies pressure to the calipers.

In disc and drum brakes, the construction and repair are almost always horizontal. The pressure from the brake pedal signals the brakes on either side of you while you are in the driver's seat. It does not require pressure from hydraulic cylinders, so your brakes respond instantaneously. Repairing the horizontal disc and/or drum braking systems, therefore, is much simpler and much faster than repairing or constructing hydraulic brakes.
