With a diameter of 325.0 mm and a mounting hole distance of 145 mm, it provides a secure and stable fit. The drum features 10 mounting holes, each with a diameter of 12.75 mm, and utilizes an M10 x 1.25 port thread. This drum is designed for the left side and is supplied without a cylinder.

Key Features & Benefits

This drum—and there are two of them, one for each rear wheel usually—houses the brake shoes. When you hit the brake pedal, those shoes press outward against the inside of the drum. That friction is what actually slows and stops the vehicle. It also provides a mounting surface for a lot of the rear brake components, like the parking brake mechanism. It’s a pretty simple system, really. This drum is part of your rear braking system, working alongside your front brakes to bring the car to a stop. It’s a core component for safety. Older vehicles or some trucks often use drum brakes on the rear, though a lot of newer cars use discs all around. It’s a mechanically operated system; the force from your foot travels through hydraulic lines and then pushes those shoes against the drum.

Symptoms, Risks & Replacements

Well, obviously, brakes are pretty vital. But this drum specifically takes a lot of abuse. It gets heated up from friction, constantly hammered by the brake shoes, and exposed to road grime. Over time it can wear down, get warped, or develop cracks. If it gets too worn or damaged, you’ll notice if your brakes feel spongy, pull to one side when you’re stopping, or hear noises like grinding or squealing. It acts like a shield protecting the internal components, but it will eventually wear out. Neglecting this part can lead to a loss of braking power, which is something you definitely want to avoid. You can find a replacement like this one easily enough, Fixparts Online carries a good selection of OEM parts. Just make sure you get the right size for your car, and I’d always recommend replacing drums in pairs for even braking.
