Swapping Out a Disc Brake Rotor — The TRW Way
> Disc brake rotors are dead important for good stopping power. They're the surface your brake pads clamp onto. Over time, especially on something like a Nissan Skyline or a gruntier Infiniti FX 50, they can wear, warp, or crack, making braking a bit dodgy.
What Clued You In?
• Brakes sound like a flock of seagulls arguing?
• Steering wheel's doing the shimmy when you brake?
• Taking longer to pull up at the lights?
• Rotors look like they've been through the wringer?
WOF Worries?
Dodgy rotors are a quick way to fail a WOF here in NZ. They gotta be thick enough and not cracked to pass the test.
DIY or Get a Pro?
Skill Level: 6/10
Time Needed: An hour or two per rotor
Gear You'll Need: Jack, stands (never skip these!), lug wrench, socket set, torque wrench, brake cleaner, maybe a caliper tool.
🛠️ Bob's "Get It Done Right" Companion Checklist
Before you get cracking, mate, safety first! Grab some safety glasses to keep the grit out of your peepers and nitrile gloves for clean hands. Give everything a good blast with Brake Cleaner to get rid of that nasty brake dust. And don't forget a smear of anti-seize caliper grease on the right spots to keep things smooth for next time.
Bob's Two Cents
Worn rotors are a no-brainer when it comes to safety on your Nissan Elgrand or Infiniti Q60. Get them sorted to keep your braking spot-on and avoid wrecking other bits. Pop into Bob's Shop for a yarn – I'll help you nail the right part for your ride!
Fitment Lowdown
Double-check the new rotors match your car's specs – diameter, thickness, bolt pattern. Some, like that Infiniti M 30d, might have special needs. Always do rotors in pairs for balanced braking, yeah?

🛠️ Bob's Pro Tip: Do the Job Right!
> If you're swapping out these parts on your vehicle, always install fresh brake pads. Check out our compatible TRW Brake Pads (Part No. GDB3312DT) 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.
