MAN 85500012173 brake pressure regulator

Description

The MAN 85500012173 is a brake pressure regulator. It is a critical component within the brake system of commercial vehicles, responsible for maintaining consistent brake force distribution to ensure safe and controlled stopping power. This regulator is designed for use in heavy-duty applications requiring reliable brake performance. The regulator ensures optimal braking balance, improving stopping distances and overall vehicle stability. Its robust construction and precise engineering contribute to long-term durability and reduced maintenance needs. Dimensions are 254 x 205 x 270 mm.

Key Features & Benefits

This little guy basically manages how much braking force goes to the rear wheels. It's designed to limit the pressure—prevent it from getting too high—so the rear wheels don’t lock up before the fronts during hard braking. It's a mechanical valve, so it uses internal springs and levers to adjust the flow. Some are adjustable, some aren't. It’s a crucial part of your braking system, sitting in the brake line somewhere between the master cylinder and the rear wheel cylinders or calipers. It works alongside your master cylinder and other brake components to create balanced braking. It doesn’t make the brakes work, it helps keep them working correctly. Think of it as a safety net for rear brake lockup.

Symptoms, Risks & Replacements

If this regulator fails, or isn’t working right, your rear brakes can lock up easily during hard stops. That’s not good – it can cause skidding, loss of control, and obviously increases stopping distances. You’ll notice if it's failing because the rear wheels might lock up before the fronts, or your car might pull to one side when you brake. It’s a safety item, plain and simple. You can find these fairly easily, Fixparts Online carries a good selection, and getting a replacement if yours is suspect is definitely worth it for peace of mind.
