Hella Pagid 355021831 Rear Brake Pads, Mercedes C-Class

If you're chasing a rear brake job on a Mercedes-Benz C-Class, the Hella 355021831 pad set is the honest, no-drama way to get it done. It's a low-metallic disc brake pad set engineered to match the factory rear pads on the W205 C-Class, the generation that ran from roughly 2015 through 2023. That means it lines up with Mercedes OE part 0004203602, drops into the stock rear calipers, and gives you back the pedal feel the car left the factory with.

Low-metallic is the sweet spot for a daily-driven sedan like this. You get real stopping bite when you need it, the kind that holds up on a fast highway off-ramp, without the harsh grab and constant squeal that fully metallic race pads bring. The small amount of steel in the friction mix helps pull heat away from the rotor, so repeated stops in stop-and-go traffic don't cook the pad or fade the pedal. For most C-Class owners, that's exactly the balance you want. Firm, quiet, predictable.

Here's what you're buying. This is a set of 2, covering the rear axle of the car. Hella builds these to the same friction standards that supply German brake systems straight off the assembly line, so the compound, the backing plate, and the fitment all match what the car expects. No modifying, no shimming odd-ball pads to fit, no guessing whether the wear pattern will be right. They seat against the factory rotors the way the engineers intended.

A quick, important note on the wear sensor. The W205 rear brakes use an electronic pad wear sensor that tells the dash when it's time for pads. This set is the friction pads themselves. If your old sensor is worn through or damaged, plan on grabbing a fresh sensor at the same time and clip it in during the install. It's a cheap part and a five-minute job while you've already got the caliper open, and it keeps the brake warning light behaving the way it should.

Who's this for? Anybody doing their own rear brakes on a C 200, C 250, C 300, C 350, or the 4MATIC variants of the W205 body. It's a straightforward afternoon job with the right tools. Pull the wheel, unbolt the caliper, compress the piston, swap the pads, and torque everything back to spec. If you're pairing new pads with new rotors, even better, they'll bed in cleanly together. One thing to know up front: this set is for the standard C-Class rear brakes, not the high-performance C 63 AMG, which runs a different, larger caliper and pad.

Why Hella? The brand has spent decades making brake friction for European vehicles, and that reputation is the reason we stock them. When you buy an OE-grade pad instead of the cheapest box on the shelf, you're buying consistency. Even friction across the pad face, a backing plate that won't flex, and a compound that behaves the same on the first stop and the thousandth. That's what keeps a heavy German sedan stopping straight and quiet mile after mile.

One last tip on install. Once the new pads are in, bed them in properly before you lean on them hard. A series of moderate stops from around 35 mph, easing off between each so the brakes can cool, transfers an even layer of friction material onto the rotor and sets the pad up for a long, quiet life. Skip that step and you're more likely to end up with uneven deposits and a pulsing pedal down the road. Ten minutes of careful bedding pays off every time you touch the brakes after.

Bottom line, if your rear pads are worn and you want a replacement that fits like the original and stops like the original, this is the set. It ships fast, it fits the W205 C-Class rear axle, and it takes the guesswork out of the job. Order it with a sensor and a set of rotors if yours are due, and you've got everything you need for a complete rear brake refresh in one go.
