Key Features & Benefits

This cylinder’s main job is to control the air pressure going to the spring brakes on your trailer or truck. It essentially manages when those spring brakes apply and release. It has three positions – that's where the “Tristop” name comes from. One position releases the brakes fully, another applies the spring brakes partially – think parking brake – and the third applies them fully for emergency stopping or when you’re parked for a longer time. It's a mechanical and pneumatic switch, basically. It’s a key part of your air brake system, sitting between the brake pedal and the actual brake chambers. When you push the pedal, it doesn’t directly push the brakes on. It sends air pressure through this Tristop cylinder. The cylinder then decides how much air goes to the brakes, and therefore how hard they grip. It’s the control center for those spring brakes. Think of it as the traffic controller for your braking system.

Symptoms, Risks & Replacements

Well, without this working right, you don’t have proper control over your spring brakes. You could have brakes that don’t release fully, causing drag and overheating, or brakes that don’t apply when you need them. You’ll notice if it’s failing; you might get a low air warning, or your brakes could drag, or maybe they won’t hold properly when parked. It’s a safety critical component, honestly. We carry these at Fixparts Online, and it’s something you definitely don’t want to mess around with. A faulty one can cause real trouble, so it's best to replace it if you suspect it’s going bad.
