Description

This screw is a critical component used in brake drum systems, specifically within the mechanical brake assembly. Manufactured by Wabco with MPN 13730121, this screw ensures secure fastening and proper functionality of the brake drum.

This component’s robust design contributes to the overall safety and longevity of the braking system.

Key Features & Benefits

These little guys actually do a pretty important job holding the brake drum itself onto the wheel hub. They secure the drum – that’s the big metal cylinder – so it spins with the wheel when everything’s working right. They don’t move during braking, they just keep everything lined up and tight beforehand. There's usually a few of them spaced around the drum. Basically, it’s a critical fastening component within your braking system. The brake shoes press against the inside of the drum to slow the vehicle, and this screw makes sure that drum stays put during all that. Without it, the drum could wobble, get misaligned, or even come loose – definitely not something you want happening while you're driving.

Symptoms, Risks & Replacements

Well, if these screws fail, it's a big deal. You’ll notice if one goes missing or breaks, because the drum won’t be held securely. It’ll cause vibrations, noises – a really concerning shudder, usually – and seriously impact your ability to stop safely. It acts like a shield, keeping everything in the right position. Replacing a worn or damaged screw is cheap insurance against a much more expensive brake repair down the road. You can find these pretty easily, even on sites like Fixparts Online if you want to do it yourself. It's a small part, but a vital one.
