Hella Pagid 355012741 Rear Brake Pads, Mercedes

The Hella Pagid 355012741 is a rear-axle disc brake pad set built for a long list of Mercedes-Benz cars and the GLK crossover. It's a low-metallic pad, and the set carries four pads, which is everything you need to redo both rear wheels in a single job. No guessing, no ordering a second box halfway through the afternoon.

Fitment covers the W204 C-Class, the W212 E-Class, and the X204 GLK. That means the C250 from 2012 to 2015, the C300 from 2008 to 2014, the C350 from 2008 to 2015, the E350 from 2010 to 2014, the E400 from 2015 to 2017, the E550 from 2010 to 2017, plus the GLK250 in 2013 and 2014 and the GLK350 in 2010 and again from 2013 to 2014. That's a wide net. Because Mercedes ran more than one rear brake size across these years, always confirm the fit against your VIN before you order, and if your car left the factory with an optional sport brake package, double-check the pad size before you commit.

So what does low-metallic actually mean? These pads use a friction mix with a modest amount of steel and other metal fibers blended into the compound. That metal content helps the pad bite cleanly and shed heat, so you get steady, predictable stops whether you're crawling through traffic or hauling the family down the interstate. It's the kind of pad that just works and doesn't ask for much thought once it's in.

The set is machined for the factory caliper bracket, so it seats in the original hardware the way the Mercedes pad did. Pad dimensions come in at 122.5 mm wide, 54.3 mm and 52.2 mm tall across the two shapes, and 17.9 mm thick, which matches the original pad footprint. It also cross-references the Mercedes OE numbers 0054200720, 0054204220, and 0054204320, among others, so you can check it against the part coming off the car.

One thing worth calling out. This pad is prepared for the electronic wear-indicator contact, but the sensor itself is not in the box. If your car uses a rear wear sensor and yours is worn or damaged, order it separately. The matching Hella Pagid accessory is the 8DZ 355 201-501. Plenty of these cars carry the wear sensor on one axle only, so check what your car actually has before you buy.

A few install notes from folks who do this all day. Replace pads in complete axle sets, never one wheel at a time, so braking stays even side to side. Clean the caliper slides and hardware while you're in there, and compress the piston slowly. If your car has an electronic parking brake on the rear, you'll need to put it into service or maintenance mode before you push the pistons back, then reset it after. And these are pads for a steel disc, so they're not meant to run against a ceramic composite rotor. If your car has those, you want the matching pad for that system.

Once everything's buttoned up, bed the pads in. A series of moderate stops from around 35 mph down to a walking pace, with a little cool-down between them, lays a clean transfer layer onto the rotor and sets the pad up for quiet, consistent braking. Skip that step and you're more likely to chase noise and uneven bite for the first few hundred miles. It's five minutes of easy driving that pays off for the life of the pad.

Bottom line, this is a straightforward OE-style replacement for a rear brake job on one of these Mercedes models. You get the full axle's worth of pads in one set, a friction compound tuned for daily driving and highway miles, and a fit that matches the factory setup. Pair it with fresh rotors if yours are past spec or scored, grab the wear sensor if your car needs one, and you're set for a clean, quiet job in the driveway or the shop.
