Wabco 4231050740 Brake Chamber Cam

Description

The Wabco 4231050740 Brake Chamber Cam 20 is a critical component within the air brake system of commercial vehicles. It’s designed for use in brake actuators, translating air pressure into mechanical force to apply the brakes. This cam features a robust design with dimensions of 195 x 190 x 125 mm, ensuring durability and reliable performance. Its technical specification adheres to OE standards, offering precise operation with a 75.0 mm stroke and a return-spring force of 220 N. The cam provides consistent and powerful braking performance with an output force of 8200 N, while operating effectively within a temperature range of -40°C to +80°C.

Key Features & Benefits

This little guy basically translates the air pressure from your brake chamber into actual mechanical movement. It’s a shaped piece inside the chamber that a pushrod rides on. As air fills the chamber, it pushes on this cam, and that cam then pushes the pushrod, which ultimately applies the brakes. It's all about converting air power into stopping power. It's part of the air brake system on larger vehicles – trucks, buses, trailers, that sort of thing. It’s a critical component inside the brake chamber itself. Think of the brake chamber as the muscle, and the cam as one of the key levers that makes it work. Without a properly functioning cam, you won’t get consistent, strong braking.

Symptoms, Risks & Replacements

It’s important because it directly impacts your stopping ability. If this cam is worn, cracked, or sticking, it won't translate the air pressure correctly. You’ll notice if it's really bad – maybe slow response when you hit the brakes, or uneven braking between wheels. Even small wear can lead to bigger issues over time, making the whole brake job less reliable and potentially unsafe. We carry a good selection of these at Fixparts Online, and it's one of those parts where preventative maintenance is really worthwhile. Replacing it when you do other brake work can save you trouble down the road.
