Trailer Axle Hub Assembly Disc Brake 13" Wheel Hub Disc Brake For Trailer Axle
How do brakes work?
The driver presses on the brake pedal, the surge of you stopping actuates the piston in the master cylinder (MC). If you have electric/hydraulic actuator the electric signal ramps up the motor and builds pressure. The piston in the master cylinder displaces the hydraulic fluid in the brake lines. Because the system is sealed, the displacement (movement) of the hydraulic fluid moves the piston(s) in the brake calipers. The moving calipers bring the brake pads into contact with the rotor. At this point, because there is no more movement possible in the system, pressure begins to build, and the pads are pressed harder and harder against the rotor, creating friction, and stopping the trailer.

Our Advantage
1. Heat sink
the groove between the mounting surface and the heat sink is used to achive better colling effect, prevent the brake disc deformation and ensure the friction .
2. Edge marking
Complete batch number and date ,part number and minimum thickness data are permanently marked on the rim of the brake disc.
3. Locating Hole
Large automatic numerical control equipment of the European standard , automatic machining process to achieve high accuracy of hole diameter and the precise positioning of the plate
4. Surface treatment
To ensure brake performance of the brake disc and to maximize the performance of the brake disc, in the two processing operation on the friction surface of high quality surface treatment .
