Disc Brake Rotor Replacement Guide — Sorted with RDA
> Disc brake rotors are dead important for good braking. They wear down over time from the pads rubbing, especially in city cars like the Hyundai i20 and Kia Rio where you're always stopping. This makes your brakes less effective and can be risky.
Symptoms That Led You Here
• Squealing or grinding noises when braking
• Vibration or pulsation felt in the brake pedal
• Increased stopping distance
• Visible scoring or damage on the rotor surface
• Brake pad wear is uneven
Will it pass WOF?
Worn or dodgy brake rotors are a quick way to fail a WOF here in New Zealand. They need to be thick enough and not too damaged to pass the test.
DIY or Workshop?
Difficulty: 6/10
Estimated Time: 1-2 hours per rotor
Tools Required: Jack and stands, lug wrench, socket set, torque wrench, brake cleaner, and potentially a brake caliper tool.
🛠️ Bob's "Get It Done Right" Companion Checklist
Alright, before you get stuck in, a few quick things to keep you safe and the job tidy:
• Safety First, Mates! Never, ever get under a car that's only held up by a jack. Use proper Jack Stands. No exceptions!

• Glove Up: Protect your hands with some heavy-duty Nitrile Gloves. Keeps the grease and grime off.
• Stop the Squeaks: A wee bit of Anti-Seize Grease on the caliper bolts will make life easier next time. Plus, it stops annoying squeaks.
• Eyes Protected: Get yourself some Safety Glasses to keep the brake dust out of your eyes.
