Disc Brake Rotor Replacement Guide — Sorted with TRW
> Your Mercedes-Benz S-Class relies on its disc brake rotors to bring you to a halt safely. Over time, they cop a beating from heat and friction, especially if you're often in stop-start traffic. Ignoring worn rotors means dodgy braking and risks to your safety.
Spotting the Warning Signs
• Brakes squealing like a stuck pig?
• Feeling a judder through the brake pedal?
• Taking longer to stop than usual?
• Rotors looking rusty, scored, or generally sad?
• Brake pads wearing unevenly?
WOF Woes?
Dodgy brake rotors are a surefire way to fail your WOF here in NZ. Your rotors need to be above the minimum thickness and in good nick to pass the test.

🛠️ Bob's "Get It Done Right" Companion Checklist
Alright, before you get cracking on those brakes, let's talk safety and making sure you've got all the right bits and bobs. First up, safety glasses are a no-brainer – you don't want any brake dust or crud in your eyes. Grab some heavy-duty nitrile gloves too; they'll keep your hands clean and protected from all the grime. Now, give those rotors a good blast with some Brake Cleaner to get rid of any carbon dust or grease. And while you're at it, a bit of Anti-Seize Caliper Grease on the caliper bolts will make life easier next time you're in there. Remember, never get under a car only supported by a jack. Use proper stands!
Expert Recommendation
Worn brake rotors are a serious safety issue for your Mercedes-Benz S-Class. Replacing them will restore your braking performance and give you peace of mind. TRW rotors are a top choice, but CARFIX has options for every budget. Bob @ CARFIX is your man for finding the right parts for your Mercedes-Benz S-Class. Swing by Bob's Shop for a yarn!
Fitment Notes
Double-check that this rotor fits your specific S-Class model and year, as brake setups can vary. Always replace rotors in pairs (both sides of the axle) to keep your braking balanced.

🛠️ Bob's Pro Tip: Do the Job Right!
> If you're swapping out these parts on your vehicle Sl, always install fresh brake pads. Check out our compatible TRW Brake Pads (Part No. GDB1543) to ensure a perfect bed-in and get the job done properly first time!
🧰 What Else You'll Need:
• Safety First: Never work under a vehicle supported only by a jack. Always secure it on heavy-duty safety jack stands.
• Brake Dust Protection: Keep a pack of Nitrile Gloves handy to protect your hands from grease and dust.
• Clean and Prep: Use Brake Cleaner to clean the anti-corrosion shipping oil off the new rotors before mounting the calipers.
• Lubrication: Apply caliper grease to caliper slide pins and pad contact points to prevent squealing.
