PHA422 TRW Brake Hose

These hoses basically carry brake fluid – that’s the hydraulic pressure that actually makes your brakes work – from the master cylinder, where you push the pedal, to the calipers at each wheel. They’re flexible rubber lines, and they have to be, because the wheels move up and down with the suspension, and the body of the car doesn’t. So they allow that movement while still securely delivering the fluid. They’re built to withstand a lot of pressure, too. Think of them as a vital link in the braking system. Everything starts with you hitting the pedal, that pressure gets sent through lines and into these hoses, then finally to the brakes themselves. Without them functioning properly, you simply won’t be able to stop reliably. They connect the rigid brake lines to the rotating parts of your vehicle – the wheels. It's a critical connection. This is important because brake fluid doesn’t compress. So if there’s any weakness or leak in a hose, even a tiny one, it creates a loss of pressure. That means it’ll take longer to stop, and you’ll need to push the pedal further. You’ll notice if one is failing, usually because the brake pedal will feel spongy or soft. The hose acts like a shield protecting the brake fluid and maintaining that pressure. Over time, the rubber can crack, swell, or get worn from road debris, salt, and just general age. A failing brake hose is a serious safety issue. If you’re doing any work on the brakes, it’s always a good idea to inspect these, and if they look questionable, replace them. We carry a good selection here, and you can also find them on Fixparts Online, easy enough. Choose TRW: Brake Hose (MPN PHA422) is protected by a 12-month warranty!
