8-94223-500-0 Cast Iron Drum Brake Cylinder with Brass Fitting

Product Overview
The 8-94223-500-0 Cast Iron Drum Brake Cylinder with Brass Fitting is a wheel cylinder used in a hydraulic drum brake system. When the brake pedal is pressed, hydraulic pressure reaches the wheel cylinder, causing its internal pistons to move outward and push the brake shoes against the inside of the brake drum. This movement creates the friction needed to slow or stop the vehicle.
The part number 8-94223-500-0 is associated with an Isuzu brake wheel cylinder. Available aftermarket catalog data links this number with applications including Chevrolet LUV, Honda Passport, Isuzu Amigo, Isuzu Axiom, Isuzu Pickup, and Isuzu Rodeo. 

Core Function
The main job of a drum brake cylinder is to convert hydraulic pressure into mechanical movement.
Inside the cylinder are pistons and sealing components. When hydraulic brake fluid enters the cylinder, pressure moves the pistons outward. The pistons then act on the brake shoes, allowing the shoes to contact the brake drum.
For the 8-94223-500-0, the available catalog information identifies it as a brake wheel cylinder and associates the part number with a 22.22 mm bore diameter. Related catalog data also lists a rear wheel cylinder position for corresponding Isuzu numbers.
The brass fitting shown in the product description provides the connection point for the brake hydraulic line. The cast iron body provides the main housing for the internal hydraulic components.

The basic working process can be understood as:
Brake pedal → hydraulic pressure → wheel cylinder → brake shoes → brake drum
This makes the wheel cylinder an important link between the vehicle's hydraulic brake system and the mechanical movement of the drum brake shoes.

Customer Pain Points Solved

1. Difficult Part Number Matching
Brake components can have similar shapes but different dimensions. Using 8-94223-500-0 as the primary search reference helps purchasing teams narrow down the correct product family. Cross-reference numbers can also help distributors connect different catalog systems when selling into different markets.

2. Unclear Vehicle Compatibility
A wheel cylinder should not be selected from the image alone. The available catalog information connects this part number with several vehicle applications, giving buyers additional information for compatibility checks.
For bulk orders, buyers can provide vehicle information or OE numbers to the supplier before confirming the order.

3. Need for Replacement Drum Brake Components
Although many newer vehicles use disc brakes, drum brake systems remain relevant in replacement-parts markets. A wheel cylinder is a relatively compact component, making it suitable for distributors that need to stock individual hydraulic brake components for specific vehicle applications.
