Hella Pagid 355021511 Rear Brake Pads, Mercedes S-Class

The Hella Pagid 355021511 is the rear disc brake pad set for the 2013 to 2020 Mercedes-Benz S-Class, the W222 sedan and C217 coupe generation. It's a complete axle set. Four pads in the box, enough to do both rear wheels in one service, so you're not chasing a second package halfway through the job. If your S-Class is due for rear pads, this is the part that goes on the car.

Hella Pagid pads are built to match the original equipment fit and feel on European cars, and the S-Class is exactly the kind of heavy, fast luxury sedan that punishes a cheap pad. This set is formulated to give you quiet, confident stops without coating the wheels in dust after a week of driving. That matters on a car with open, polished rear wheels where every speck of brake dust shows.

The S-Class is a two-ton-plus car that's happy at highway speed, and its brakes do real work every time you slow it down. Rear pads on this platform carry more of the load than they would on a lighter car, especially in stop-and-go traffic and on long downhill grades where the system leans on all four corners. That's why matching the original friction character matters here. You want the car to stop the way it did when it left the factory, with a firm pedal and no fade when the brakes get hot.

The set ships with the brake caliper screws and the small accessory hardware you need for the job. Mercedes calls for fresh caliper guide bolts and retaining hardware at a pad change rather than reusing the old ones, and having them in the box means you're not making a second parts run. The pads are also prepared for the factory wear indicator, so the sensor circuit that lights the dash keeps doing its job. The electronic wear sensor itself is usually a separate item, so check your existing sensor and swap it if it's worn through or already triggered.

A few things to know before you dive in. The W222 and C217 use an electronic parking brake on the rear calipers. Before you push the caliper pistons back, put the parking brake into service or retract mode with a capable scan tool. Force the pistons back by hand and you can damage the actuator. Once the calipers are open, measure your rotors against the Mercedes minimum thickness and look for deep scoring or a hard lip. Pads and rotors wear as a pair, so if the discs are near their limit it's worth doing both while you're in there.

This set covers the full range of 2013 to 2020 S-Class trims, from the gas inline-six and V8 cars to the S550e and S560e plug-in hybrids and the Maybach S-Class. On the plug-in hybrid cars, regenerative braking does a lot of the low-speed slowing, so the rear pads often last longer than you'd expect. When they finally need replacing, this is still the correct part. The friction material and the mounting are the same across the range.

What this set is not: it's not a front pad set, and it's not a universal fit. It's the rear axle for one chassis family. If you've got an older S-Class or a different Mercedes line, this isn't your part. Confirm the fitment before you order by matching the part number 355021511 or one of the Mercedes OE numbers, 0064205720, 0064209220, or 0074202820, to your VIN in a parts lookup. A quick check now saves a return later.

When the new pads are on, bed them in properly. A series of moderate stops from moderate speed, easing off before you come to a full stop, lets the friction material transfer an even layer onto the rotor. Avoid hard, panic stops for the first couple hundred miles. Do that, and you'll get the quiet, even braking these pads are built to deliver for the life of the set.
