Wabco 4725002220 Rear Axle Package with ABS/ASR

Description

The Rear Axle Package with ABS/ASR is a critical component of a vehicle's braking system, specifically designed for use in applications requiring anti-lock braking and electronic stability control. This Wabco unit (MPN 4725002220) modulates brake pressure at each wheel to prevent locking during braking and maintain vehicle control. It features dimensions of 170 x 174 x 320 mm and is built to withstand harsh environments with protection classes of IP66 and IP69K. Its robust design, operating within a temperature range of -40°C to +80°C, ensures reliable performance in diverse conditions, and the OE specification guarantees compatibility and optimal functionality within the vehicle’s system. This package operates at 12V, features a max operating pressure of 11.0 bar, and utilizes connections like DIN 72585-A1-3.1-Sn/K1 and DIN 72585-A1-2.1-Sn/K1.

Key Features & Benefits

This package isn’t just one thing, it’s a few components working together. Primarily it controls how hard the brakes apply to the rear wheels, and it does that through the ABS hydraulic unit. That unit takes signals from wheel speed sensors – little guys that monitor how fast each wheel is spinning – and uses those signals to regulate brake pressure. The ASR part, or traction control, builds on that. It detects when a rear wheel starts to spin faster than the others – like when you’re on a slick surface – and it uses the brakes to slow that wheel down, helping to keep you pointed where you want to go. It also includes the necessary lines and sometimes the bracketry to get it all connected properly. Think of this as the brains behind preventing wheel lockup and managing traction at the rear. It’s a key part of your vehicle’s overall safety system. It works with your regular brakes – it doesn't replace them. It’s constantly monitoring what's happening with your wheels and stepping in to make adjustments when needed. If you’ve ever felt the brake pedal pulse under your foot during hard braking, that’s the ABS system at work.

Symptoms, Risks & Replacements

Well, without this working correctly, you lose a lot of control, especially in slippery conditions. It’s really vital for preventing skids and maintaining stability. You’ll notice if it fails – usually by the ABS light illuminating on your dash, and potentially by experiencing longer stopping distances or a feeling of instability during braking. It’s a pretty serious safety component. If you’re doing a brake job or have issues with the ABS system, it’s best to address this package promptly. We carry a good selection of these at Fixparts Online, and I can help you find the right one for your specific vehicle if you’d like.
