AISIN's original equipment technology and know-how is applied to design and engineer hydraulics. Each part is manufactured vehicle specific, ensuring product quality and reliability. Exacting OE standards and quality must be met for hydraulics, especially for safety items such as brake hydraulic components. Passing the same strict OE standards, there is no questioning quality, performance and reliability when all hydraulic components are manufactured in the same OE manufacturing plants.

BRAKE MASTER CYLINDER

The brake master cylinder is a device that transforms mechanical force into hydraulic pressure. As the driver presses the brake pedal, the pedal lever applies force to the brake master cylinder which transmits hydraulic pressure to the rest of the brake system components such as the ABS unit, brake calipers and wheel cylinders.

BRAKE WHEEL CYLINDER

Brake wheel cylinder is a component in a drum brake system. It is located in each wheel and is usually positioned at the top of the wheel, above the shoes. Its function is to exert force onto the shoes so as to bring them into contact with the drum and stop the vehicle with friction. The wheel cylinders are usually connected to the shoes with small bird-beak shaped rods.

It is very similar to a slave cylinder and functions in much the same way, internally consisting of only a simple plunger. On older vehicles these may begin to leak and hinder the performance of the brakes, but are normally inexpensive and relatively easy to replace.

The wheel cylinder consists of a cylinder that has two pistons, one on each side. Each piston has a rubber seal and a shaft that connects the piston with a brake shoe. When brake pressure is applied, the pistons are forced out pushing the shoes into contact with the drum. Some designs use two single piston wheel cylinders, one at the top of the drum and one at the bottom, each connected to one brake shoe.

Wheel cylinders must be rebuilt or replaced if they show signs of leaking. Wheel cylinders used to be made of cast iron. However, they were more prone to rusting and aluminum is now the preferred material.

CLUTCH MASTER CYLINDER

The clutch master cylinder is a device that transforms mechanical force into hydraulic pressure. As the driver presses the clutch pedal, the pedal lever applies force to the clutch master cylinder which transmits hydraulic pressure to the clutch release (slave) cylinder that disconnects engine power to the transmission.

CONCENTRIC SLAVE CYLINDER

AISIN’s CSC has less loss stroke in CMC compared with other products. A clutch can be controlled with weaker pedal power. CSC has the function of clutch release cylinder and release bearing. Benefit of CSC clutch system.

  • Decrease the force on pedal
  • Decrease stroke weight for disconnecting clutch
  • Avoid degradation of quality due to friction coefficient increase
  • Reducing the number of component (Merge component)
