Hella Pagid 355129371 Vented Brake Disc, 356mm 5 x 112

The Hella Pagid 355129371 is a direct-fit replacement brake disc for vehicles running a 5 x 112 mm wheel bolt pattern. It's a vented, one-piece rotor cast from gray iron and finished with a zinc coating, so you're getting a proven brake design that bolts on and gets right back to the business of stopping your car. If your current rotor is scored, warped, or worn past its minimum thickness, this is the kind of straight replacement that puts your braking back where it should be.

Let's talk about the vented design first, because it matters more than most people think. A vented rotor isn't a single solid slab. It's two friction faces with internal cooling vanes cast between them. As the disc spins, those vanes pump air through the middle of the rotor and pull heat out of the braking surface. That's what keeps your brakes feeling consistent when you're hauling a load down a long grade, running back-to-back stops in traffic, or pushing hard on a twisty road. Heat is the enemy of good braking, and a vented disc is your first line of defense against fade.

The 355129371 is a one-piece casting. The hub section and the friction ring are formed as a single piece of gray cast iron, which is the design that's been stopping cars reliably for decades. There's nothing to come loose between a separate hat and ring, and installation is about as simple as brake work gets. Slide it on, torque your caliper bracket and pads to spec, and you're done. Gray cast iron also sheds heat well and takes repeated thermal cycles without complaint, which is exactly what you want in a daily-driven brake rotor.

The zinc coating is a detail you'll appreciate a few months down the road. It protects the hat, the edges, and the other non-friction surfaces from rust. If you live where winters mean salted roads, or you just deal with a lot of rain and humidity, that coating keeps the rotor from turning into a crusty orange mess behind an open wheel. The friction surface itself wears clean as your pads sweep it, and everything else stays protected.

Here are the numbers that matter. The disc measures 356 mm in outer diameter, which is a large swept area for strong, confident stopping power. Nominal thickness is 34 mm, and overall height is 52.1 mm, which sets the correct hat depth so the rotor seats flat against your hub. The center bore is 68 mm, and the wheel bolt pattern is 5 x 112 mm. Every one of those measurements has to line up with your vehicle, so treat them as a checklist against your original part.

A quick word on fitment. The 5 x 112 mm bolt pattern is shared across a lot of European platforms, including many Audi, Volkswagen, and Mercedes-Benz models. But bolt pattern alone never guarantees a fit. Diameter, thickness, hat height, and hub bore all have to match too. The cleanest way to be sure is to match the Hella Pagid part number, 355129371, to your exact year, make, and model. When in doubt, pull your old rotor and measure. We'd rather you check twice than order twice.

This rotor is sold individually. Brakes work as a system, and they work best when both sides of an axle are even, so for most jobs you'll want two of these and a fresh set of pads to go with them. New pads bed cleanly against a new disc and give you full, even contact from the start. Once everything's installed and torqued, run a proper bed-in, a series of moderate stops from moderate speed, to lay down an even layer of pad material on the disc. Do that and you'll get quiet, smooth, consistent braking right away.

Who's this for? Anyone doing their own brake service, or a shop that wants a solid, no-drama replacement rotor for a 5 x 112 mm European setup. It's honest cast iron done right, vented for heat, coated for corrosion, and cut to real Hella Pagid specs. Confirm the fit by part number, buy them in pairs, and get back on the road.
