MAN 81504109512 spring brake cylinder

Description

The MAN 81504109512 spring brake cylinder is a crucial component within the air brake system of commercial vehicles. It's responsible for converting air pressure into mechanical force, applying the brakes when activated, and holding the brakes engaged when the system is pressurized. This cylinder is commonly found in truck and trailer applications, ensuring reliable stopping power and parking functionality. Its robust construction and precise engineering contribute to consistent brake performance, enhanced safety, and reduced maintenance needs. This cylinder has dimensions of 185 x 200 x 430 mm.

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.
