Description

The Wabco 4800021230 Brake Signal Transmitter is a critical component within a vehicle's braking system, functioning as an integral part of the Brake Control Unit (ABS & ESC).

Engineered to OE specification, this transmitter ensures precise and reliable communication for optimal braking performance and vehicle safety, contributing to enhanced control and stability on the road.

Key Features & Benefits

This little guy takes the information from your brake pedal – how hard you’re pressing, basically – and sends it as an electrical signal to the car’s computer, the ABS and ESC systems. It tells them when you’re braking, and how urgently. It’s also involved in things like activating your brake lights, and even helping systems like adaptive cruise control work correctly. Think of it as a messenger. Your foot presses the brake, that movement needs to be communicated to the car’s ‘brain’ so it can react. It’s part of the larger brake control system, which includes the ABS module and ESC system, and works with the wheel speed sensors to manage braking force. It’s typically located near the master cylinder or the ABS module itself.

Symptoms, Risks & Replacements

It’s pretty crucial, honestly. If this thing goes bad, a lot of things can happen. You might notice your brake lights aren’t working correctly – that's a safety issue right there. Or the ABS and stability control systems might not engage when they should, which affects your ability to control the car in tricky situations. It might even cause warning lights on your dash. Sometimes you'll notice if the car feels like it's not slowing down as quickly as it should. It acts like a shield, helping all those safety systems do their job. If you're looking for a replacement, Fixparts Online usually has a good selection, and makes it pretty easy to find the correct one for your vehicle.
