Disc Brake Rotor Replacement Guide — Keep Your Landy Gripping the Road with TRW!
> Alright, let's talk rotors for your Land Rover Discovery or Range Rover Sport! These aren't just any old metal discs; they're precision-engineered bits of kit that, with your brake pads, create the magic friction needed to haul your heavy machine to a stop. Given the sheer weight and the tough conditions these beauties often face (think towing a boat or tackling some gnarly off-road tracks), your rotors can get a bit warped, thin out, or develop some nasty grooves. And trust me, that's a one-way ticket to dodgy braking and a real safety headache.
Symptoms That Led You Here
• Vibration or pulsation felt through the brake pedal or steering wheel during braking.
• Squealing, grinding, or scraping noises when braking.
• Extended stopping distances, indicating reduced braking efficiency.
• Visible scoring, grooves, or discolouration on the rotor surface.
• A burning smell after heavy braking.
Will it pass WOF?
No. Worn, warped, or damaged brake rotors are a significant safety concern and will cause your vehicle to fail its Warrant of Fitness (WOF) inspection in New Zealand. Rotors must meet minimum thickness specifications and be free from excessive scoring or cracking.
DIY or Workshop?
Difficulty: 6/10
Estimated Time: 1-2 hours per axle (for experienced DIYers)
Tools Required: Jack, jack stands, wheel nut wrench, brake caliper compression tool, torque wrench, socket set, spanner set, wire brush, brake cleaner, safety glasses, gloves. While technically a DIY job, proper torque settings and bleeding procedures are crucial for safety, making a workshop often the safer option for these heavy vehicles.

🛠️ Bob's Pro Tip: Do the Job Right!
> If you're swapping out these parts on your vehicle Discovery, always install fresh brake pads. Check out our compatible TRW Brake Pads (SKU GDB1631) 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.
