Wabco 4617043804 Contact Piece

Description

The Wabco 4617043804 Contact Piece is a critical component within air brake systems, functioning as part of the air valves. It’s designed for use in pneumatic braking systems to ensure reliable and efficient brake operation. This OE specification component maintains precise air pressure control and responsiveness, contributing to enhanced braking performance and safety. It measures 17 x 37 x 37 mm.

Key Features & Benefits

This little guy is basically an electrical switch that gets triggered by the brake pedal movement. It confirms to the system that the pedal is being pressed. It sends a signal that allows other parts of the air brake system, like the modulator, to actually do their job. It's a simple piece, but it’s a critical link in making sure your brakes work right. Think of it as a messenger. When you push the brake pedal, the contact piece tells the air brake system, “Hey, the driver wants to slow down!” Without that signal, the air brakes might not apply properly, or at all. It’s part of the safety net making sure the air brakes engage when you expect them to. It’s usually found near the brake pedal linkage itself.

Symptoms, Risks & Replacements

Honestly, it's hugely important. If this thing fails, it’s a safety issue. You might not get full braking power, or you might get erratic brake performance. You’ll notice if it's failing because the brakes might feel spongy, or take longer to engage. Sometimes you'll get a warning light on your dash, but not always. A bad contact piece can put a lot of stress on other parts of the air brake system too. We carry a good selection of these, and you can find a replacement at places like Fixparts Online, or right here of course. It’s a relatively inexpensive part to replace, and well worth it for the peace of mind.
