Wabco 4235140100 Brake Chamber Disc

Description

The Wabco 4235140100 Brake Chamber Disc 14 is a critical component within the air brake system of commercial vehicles. Specifically, it functions as part of the brake actuator, converting air pressure into mechanical force to apply the brakes. This disc is designed for use in heavy-duty truck and trailer applications, ensuring reliable stopping power. This component offers precise control and consistent performance under demanding conditions, contributing to enhanced safety and operational efficiency. It measures 165 x 165 x 165 mm and is manufactured to OE specification with a stroke of 57.0 mm and a maximum operating pressure of 10.2 bar.

Key Features & Benefits

This little disc – sometimes called a diaphragm – is really the heart of how your air brakes apply the brakes. It’s a flexible membrane inside the brake chamber. When air pressure is applied, it pushes on this disc, and that movement is what ultimately activates the brake shoes or pads. It essentially translates air pressure into mechanical force. It also releases the brakes when air pressure is removed; it returns to its original shape, letting things go. Think of it like this—your air compressor makes the air pressure, the lines carry it, and this disc is the muscle that actually does the work. It’s part of the brake actuator, which is the whole assembly that pushes or pulls to engage your vehicle’s brakes. It’s used on trucks and trailers with air brake systems, so it’s critical for stopping power.

Symptoms, Risks & Replacements

This thing is super important for safety. If it cracks, tears, or just gets worn out, you lose braking ability. You’ll notice if it’s failing because your brakes might feel spongy, take longer to engage, or you might even have trouble holding a grade. It acts like a shield protecting the rest of the brake system from constantly dealing with high pressures. If it fails, you risk complete brake failure. We carry a lot of these at Fixparts Online, and it’s one of those parts you really want to keep an eye on during inspections. A little preventative maintenance here can save you a lot of trouble – and money – down the road.
