Wabco 4254540200 Cylinder Head Wedge

Description

The Wabco 4254540200 Tristop Cylinder Wedge G-12/16 is a critical component within air brake systems, specifically functioning as a brake actuator. It's designed for use in heavy-duty vehicles and trailers to efficiently convert air pressure into mechanical force for braking. This cylinder wedge utilizes a wedge-type operation and features a 4-hole flange mounting. Measuring 410 x 180 x 180 mm, it delivers substantial output force – 7000 N and 5200 N – and operates within a temperature range of -40°C to +80°C. With a stroke of 53/53 mm and operating at a maximum pressure of 10.0/8.0 bar, this OE specification actuator provides reliable and consistent braking performance, ensuring vehicle safety and control.

Key Features & Benefits

This little wedge basically adjusts how your brake actuator pushes on the air brake chamber. It lets you fine – tune the stroke – how far that pushrod travels. Think of it like shimming a door hinge to get it to close just right. You use it to get everything aligned and working smoothly. It’s a simple part, but it has a specific job. It fits between the brake actuator and the cylinder head. Air brakes work with push and pull, right? This wedge allows you to adjust that mechanical linkage. It helps make sure the brakes apply and release fully and evenly. It's part of what translates the air pressure into stopping power.

Symptoms, Risks & Replacements

If this wedge isn't right, your brakes might not fully engage, or they might drag a little bit. You’ll notice if you’re getting less stopping power than usual, or maybe if your brakes are getting unusually hot. It's a safety thing, honestly. Getting the adjustment right prevents uneven wear on your brake components and makes sure your vehicle stops reliably. It’s not something you want to mess around with. You can find these pretty easily; we actually stock a good range at Fixparts Online if you’re looking. They're relatively inexpensive, but make a big difference in how your air brakes perform.
