1. Dimensions The numbers can indicate the dimensions of the seal. For instance, the first number may denote the inner diameter, the second, the outer diameter, and the third could refer to the width or height of the seal. These dimensions are critical for ensuring that the seal fits perfectly within the intended assembly, thereby maximizing effectiveness.

The materials used in manufacturing hydraulic seals are also vital to their performance. Common materials include rubber compounds, polyurethane, and PTFE (Polytetrafluoroethylene). Each material offers different advantages and is selected based on the operating environment. For example, PTFE seals are highly resistant to chemicals and extreme temperatures, making them ideal for demanding applications.

3. Improved Cooling Inboard brake drums can potentially offer better thermal management. Since they are mounted closer to the vehicle body, there is an opportunity for more efficient cooling compared to conventional systems. Improved cooling can reduce brake fade, enhancing performance during high-speed or prolonged braking situations.
