Wabco 4756043814 Pressure Plate

Description

The Pressure Plate, manufactured by Wabco, is a critical component within air brake systems, specifically functioning as an air valve component. It ensures proper air pressure regulation and release, contributing to the safe and efficient operation of commercial vehicles. This plate meets OE specifications, providing reliable performance and durability. Measuring 14 x 18 x 18 mm, its precise dimensions and robust construction contribute to consistent brake function and extended service life.

Key Features & Benefits

This little guy basically regulates the air pressure going to your brake chambers. Think of it as a gatekeeper. It takes the air from your compressor and controls how much gets released to actually apply the brakes. It has a diaphragm inside that reacts to changes in pressure, and that’s what opens and closes the valve. It also has ports – those are just openings where the air comes in and goes out – and those need to be clear for everything to work right. In your truck or trailer, it's a key part of making sure your brakes work consistently and reliably. It sits between the air compressor and the brake chambers. When you hit the brakes, the system tells this plate to release air, pushing those brake shoes or pads against the drums or rotors. It’s not doing the braking itself, but it’s telling everything else to get to work. It's part of a larger system, so everything needs to work in sync.

Symptoms, Risks & Replacements

If this plate fails, your brakes might not apply fully, or they might not release properly, which is obviously a big safety concern. You’ll notice if it's failing. You might get a long brake pedal travel, or the brakes might drag – meaning they stay partially applied even when you’re not pressing on the pedal. It's a critical component, and a worn – out pressure plate can create a seriously dangerous situation. It's one of those things you really don’t want to mess around with. We often have these in stock at Fixparts Online, and getting a replacement before it completely fails is always the smart move.
