Wabco 4254510570 Cylinder Wedge

Description

The Wabco 4254510570 Tristop Cylinder Wedge 24/24 is a critical component within air brake systems, specifically functioning as a brake actuator. It's designed to convert pneumatic pressure into mechanical force, enabling the activation of vehicle brakes. This wedge actuator features a 4-hole flange mounting and operates on a wedge principle with a stroke of 57/57 mm and a total length of 401.0 mm. It generates output forces of 7600 N and 8800 N, and functions within a temperature range of -40°C to +80°C. The actuator boasts a release pressure of 4.2 bar and a return-spring force of 150 N, and its ports utilize Rc 3/8 (ISO-7-1) threading. This OE-specification device provides reliable and consistent braking performance by precisely controlling brake application and release.

Key Features & Benefits

These little guys essentially translate air pressure into mechanical force. Your air brake system uses compressed air to push on a piston inside the wedge. That piston then pushes on other parts of the brake system – like levers and rods – to actually apply the brakes. They're a key part of how your air brakes work - converting that air power into stopping power. Think of it as a central point in your air brake system. Air comes in, the wedge expands or contracts based on the pressure, and that movement then activates the brakes on your wheels. It’s mainly found in the brake actuators, which are the mechanisms that physically push the brake shoes against the drums or pads against the rotors. You’ll find them on the axles, working alongside the brake chambers.

Symptoms, Risks & Replacements

Without a functioning cylinder wedge, your brakes just won't apply properly, or at all. It’s a safety – critical part. If it's cracked, worn, or leaking air, you’ll notice if your brakes are weak, slow to respond, or even failing completely. It’s one of those parts where replacing it proactively is way better than dealing with a brake failure on the road. Honestly, we see a lot of these needing replacement during routine brake system maintenance. You can often find a good selection of them at places like Fixparts Online, and getting the right one for your specific vehicle is super important, so double – check the fitment guide.
