MAN 85500012125 spring brake cylinder

Description

The spring brake cylinder is a critical component within the braking system of commercial vehicles, specifically designed for spring brakes. It converts the compressed air signal into mechanical force, applying the brakes when activated and releasing them when the air pressure is relieved. This cylinder is manufactured by MAN with a part number of 85500012125 and measures 400 x 195 x 195 mm. Its robust construction and precise engineering contribute to reliable and efficient braking performance, enhancing vehicle safety and control.

Key Features & Benefits

This little guy basically takes the hydraulic pressure from your master cylinder—that's what you push when you hit the brake pedal—and turns it into mechanical force that pushes out the brake shoes or pads against the drums or rotors. It's got a spring inside that pushes the piston back in when you release the pedal, so everything isn’t dragging. Think of it like a strong arm that does the actual stopping work at each wheel. It's a hydraulic actuator, really. It’s part of your braking system, obviously, and is located at each wheel. You'll have one for each brake, usually. It works with the master cylinder and brake lines to create the stopping power. It’s a slave cylinder because the master cylinder tells it what to do. It’s a key piece in getting your vehicle to slow down and stop safely.

Symptoms, Risks & Replacements

Honestly, it’s super important. If this thing fails, you'll lose braking power at that wheel. You'll definitely notice if one is going bad – pulling to one side when you brake, a spongy pedal, or even a wheel locking up are all signs. It acts like a shield between the hydraulic pressure and the mechanical action of your brakes. It needs to be reliable because your safety depends on it. We carry a lot of these at Fixparts Online, and honestly, it's one of those parts you don’t want to cheap out on – a good quality cylinder is worth it for peace of mind.
