This valve basically controls the pressure to the spring brakes – those big brakes on the rear axles of trucks and trailers. It lets the driver apply and release those spring brakes using the hand control. It manages the air going into the chambers that actually push the brake shoes against the drums. It also includes a release mechanism, so you can get everything moving again. It’s a pretty simple idea, mechanically, but it’s critical. Think of it as the central control for a really powerful, secondary braking system. Your regular air brakes are your main stopping power, but the spring brakes are there as a backup – and a serious one at that. This valve is the link between you, the driver, and those spring brakes. It also functions as a parking brake; when you pull the handle, it applies those spring brakes and holds the vehicle. It's generally mounted near the driver's seat for easy access. Well, if this valve fails, those spring brakes can lock up unexpectedly, or you might not be able to apply them when you need to. You’ll notice if it's going bad because the parking brake might drag, or it might take a lot more effort to apply and release it. More seriously, if it malfunctions while you're driving, it can cause the vehicle to pull to one side, or even lock up the wheels – obviously, a really dangerous situation. It’s a safety component, plain and simple. You can find replacements for most makes and models at places like Fixparts Online, but it’s something you definitely want to address promptly if you suspect a problem. Better than the rest: Hand Brake Valve (MPN DPM61A) includes a 12-month warranty!
