Wabco 1835104042 Guide Tube with Scraper 40mm

Description

The Wabco 18351042 Guide Tube with Scraper 40mm is a critical component within trailer air brake systems, specifically in trailer brake controls.

The tube's dimensions are 40 x 40 x 230 mm, providing a precise fit and robust durability for consistent brake function.

Key Features & Benefits

This little tube basically guides the pushrod – that’s the part that actually does the braking – as it moves in and out of the brake chamber. The scraper part? That’s a rubber piece built into the tube, and it keeps dirt, grime, and moisture off the pushrod. Think of it like a little windshield wiper, but for your brakes. It keeps things sliding smoothly. It sits between the brake chamber and the brake linkage on your trailer. Basically, when you hit the brakes in your truck, that signal gets sent to the trailer, and this tube makes sure that mechanical movement gets transferred correctly to the trailer brakes. It’s a pretty simple part, but it’s crucial for getting that force applied evenly.

Symptoms, Risks & Replacements

Honestly, this is one of those parts you don't really think about until it goes bad. But if it’s cracked, worn, or the scraper is missing, you’ll notice if your brakes aren’t responding as quickly, or if you get uneven braking – one side pulling more than the other. It acts like a shield against the elements, and when it fails, the pushrod can get corroded or sticky. That’ll wear down other parts faster, and seriously impact your stopping power. You can find these pretty easily, even online at places like Fixparts Online, and they’re relatively inexpensive to replace – a lot cheaper than dealing with brake failure.
