Wabco 100595870 Solenoid Valve

Description

The Wabco 100595870 is a solenoid valve used within the ABS hydraulic unit of brake systems. This valve controls the flow of brake fluid, enabling critical functions like anti-lock braking and stability control. It features a bayonet DIN 72 585 A1-3.1-Sn/K1 electrical connection, M22 x 1.5 and M18 x 1.5 port threads, and is designed for a maximum operating pressure of 11.0 bar. Its robust construction, boasting an IP 67 / IP 69K protection class and a temperature range of -40°C to +80°C, ensures reliable performance in demanding conditions. The valve’s dimensions are 71x20 mm, and it features a flap exhaust and a push-rod thread of M22 x 1.50. It operates at 24 V with a rated current of 1650 mA, and is manufactured to OE specification.

Key Features & Benefits

These little guys are basically electrically controlled valves. Inside your ABS hydraulic unit, they open and close really quickly, controlling the flow of brake fluid to each wheel. They don’t make the pressure, they direct it. Think of them like tiny traffic signals for your brake fluid, telling it where to go. Each wheel usually has its own solenoid, so you’ve got a few of them working together. This valve is a key part of your Anti – lock Braking System, or ABS. When your ABS system detects a wheel starting to lock up during braking—like you’re hitting ice or slamming on the brakes hard—it uses these solenoids to rapidly pulse the brakes on that wheel. That pulsing is what stops the wheel from locking, allowing you to still steer while braking. It’s all happening super fast, controlled by your car’s computer. They work with the ABS pump and the speed sensors.

Symptoms, Risks & Replacements

If one of these valves fails, it throws off the whole ABS system’s ability to control braking to that wheel. You’ll likely get an ABS warning light on your dash, and the ABS might not activate when you need it. It won't necessarily mean your brakes won't work, but you lose that extra safety net of the ABS system. It acts like a shield against skidding. You’ll notice if one fails because the ABS warning light will come on and you might feel a pulsing in the brake pedal when you don't expect it, or the ABS won’t engage at all when you brake hard. If you need to replace one, places like Fixparts Online are good for getting the right part quickly.
