Swapping Out Your Disc Brake Rotors — With RDA
> Disc brake rotors are dead important for good braking. They're what your brake pads grip to slow you down. Over time, rotors wear, warp, or crack, especially if you drive a lot in tough conditions like city traffic in your Holden Barina or Audi A4.
Spotting Trouble: Time for New Rotors?
• Brakes squealing like a gutted pig or grinding?
• Brake pedal vibrating like crazy?
• Braking not as sharp as it used to be?
• Can see cracks or damage on the rotor itself?
WOF Woes?
Worn brake rotors are a dead cert for failing your WOF here in NZ. Make sure your rotors are thick enough and free from cracks to pass the test. No one wants to fail a WOF!

Bob's Two Cents
Worn rotors mean dodgy brakes, plain and simple. Replacing them keeps you safe and stops other parts from getting damaged. Bob @ CARFIX is always keen to help you pinpoint the right part for your Audi or Holden. Pop into Bob's Shop for a yarn!
Fitment Facts
Always double-check the right fit for your exact vehicle year and model. Rotor sizes can vary, even on similar Audis and Holdens. Make sure your new rotor is the same as the old one.
🛠️ Bob's "Get It Done Right" Companion Checklist
Before you get cracking, grab these essentials to make the job safer and easier:
• Brake Cleaner: Blast away that brake dust! Keeps everything clean for reassembly. Grab a can of Brake Cleaner.
• Caliper Grease: A wee dab of anti-seize caliper grease on the right spots prevents annoying squeals and keeps things moving smoothly.
• Safety Glasses: Protect your peepers from flying dust and debris. Safety first, always!
• Nitrile Gloves: Keep your hands clean and grease-free. No one wants to spend ages scrubbing after a brake job. Get some Nitrile Gloves.
Remember, never get under a car supported only by a jack! Use proper axle stands. Bob's your uncle, you're all set!
