Hella 355122622 Rear Brake Rotor 256mm | VW Jetta Golf
Hella 355122622 Rear Brake Rotor 256mm | VW Jetta Golf — Product description
The Hella 355122622 is a direct-fit rear brake rotor for the VW MkV platform, the Jetta, Rabbit, and Golf 2.5, plus the Audi A3. It's a 256mm solid, one-piece gray cast iron disc with a zinc coating that fights surface rust in the box and on the car. Sold individually, so grab two to do the axle.
If you're chasing a soft brake pedal or a shudder under braking on a VW Jetta, this is the rear rotor that puts things right. The Hella 355122622 is a straight replacement for the rear disc on the MkV platform, the same running gear under the Jetta, the Rabbit, and the 2.5 Golf, along with the Audi A3. It's a 256mm solid disc, one piece, cast from gray iron and coated at the factory so it shows up clean and stays that way on the shelf.
Fitment is the whole ballgame with brake parts, so here's where this one lives. It's the rear rotor for the Volkswagen Jetta from 2005 through 2010 across the common engines, the 1.9 TDI, the 2.0, and the 2.5 five-cylinder. It also covers the Volkswagen Rabbit from 2006 to 2009 with the 2.5, the 2010 Golf 2.5, and the 2008 Audi A3 2.0. These all share the same rear hub and 256mm disc, which is why one part number covers the bunch. Model years and trims moved around over that run, so check your build against the OE number 1K0615601AJ or run your VIN before you order. Ten minutes on the parts counter beats a wrong box in the driveway.
The disc itself is solid, not vented, which is normal for the rear of a car this size. The rear brakes do less of the work, so a solid 256mm rotor sheds heat just fine for daily driving, commuting, and the odd spirited on-ramp. What you get for the money is honest gray cast iron with a proper zinc-style coating over the whole casting. That coating is the part people miss. It keeps the rotor from flash-rusting in the box and it keeps the hat, the edges, and the vanes looking clean long after install. Where the pad sweeps, the coating wears off in the first few stops on its own, exactly like it's supposed to. You don't scrub it off first.
A few numbers worth knowing before you turn a wrench. Outside diameter is 256mm. Nominal thickness is 11.90mm, and the overall hat height is 48.40mm. The center bore, the hole that rides on the hub, is 65mm. Because it's a thinner solid rear disc, there isn't a lot of meat to give back, so most techs run these to the wear line and replace rather than resurface. If yours are grooved, warped, or lipped, new is usually the smarter call at this price.
Install is straightforward if you've done rear brakes before. Pull the caliper and carrier, back off the parking brake if it's fighting you, and get the old rotor off. Clean the hub face down to bare metal so the new disc seats dead flat, because a speck of rust or crud right there is what causes pedal pulsation later. A smear of anti-seize on the hub register keeps the next person from cursing you when it's time to come apart again. Torque everything to spec, bed the pads in with a series of moderate stops, and you're done.
One thing to note on quantity. This is sold as a single rotor, not a pair. Brakes always get done in axle sets, so order two if you're refreshing the whole rear end, and do the pads at the same time while you're in there. That's the honest way to get an even, quiet pedal that lasts. If you just need the one because a stone or a seized caliper chewed up a single disc, one is fine too.
Bottom line, this is a no-drama rear rotor for a hugely common VW and Audi platform, coated so it lasts on the shelf and cut to the right 256mm size for a clean, direct fit. Match it to your vehicle, do it in pairs, and it'll give you a firm pedal for the long haul.

Frequently asked questions
What vehicles does the Hella 355122622 rotor fit?
It's the rear disc for the VW MkV platform. That covers the Volkswagen Jetta from 2005 to 2010 with the 1.9 TDI, 2.0, and 2.5 engines, the Volkswagen Rabbit 2006 to 2009 with the 2.5, the 2010 Golf 2.5, and the 2008 Audi A3 2.0. Trims shifted over that run, so confirm against OE 1K0615601AJ or your VIN before ordering.
Is this a front or rear rotor?
Rear. It's the 256mm solid rear disc for these VW and Audi models. The front rotors on these cars are a different, larger part.
Is the rotor solid or vented?
Solid, one piece. That's the factory design for the rear of these cars, and it sheds plenty of heat for daily driving since the rear brakes do less of the work.
Does it come as a pair or just one?
One. This is a single rotor. Brakes get done in axle sets, so order two if you're refreshing the whole rear, and do the pads at the same time.
Do I need to clean the coating off before I install it?
No. The zinc-style coating is meant to stay on the hat and edges to fight rust. Where the pad sweeps, it wears off on its own in the first few stops. Just mount it clean and bed the pads in.
What are the key dimensions?
Outside diameter is 256mm, nominal thickness is 11.90mm, hat height is 48.40mm, and the center bore is 65mm. Those match the OE rear disc so it seats flat on the factory hub.
Can I resurface this rotor instead of replacing it?
It's a thin solid rear disc, so there isn't much material to machine away. Most techs run these to the wear line and fit new rather than cut them, which at this price is usually the smarter move.
What should I watch for during install?
Clean the hub face down to bare metal so the disc seats dead flat, since crud there is what causes pedal pulsation later. A little anti-seize on the hub register makes the next removal easier. Torque to spec and bed the pads in with a series of moderate stops.
