Disc Brake Rotor Replacement Guide — Keep Your Classic Mitsubishi Stopping Sweet!
> Disc brake rotors are like the unsung heroes of your braking system, those trusty metal discs that your brake pads clamp onto, turning all that go-fast energy into heat to slow you down. After years of tackling our Kiwi roads, all that heat, wear, and even a bit of rust can make them warp, crack, or get too thin. When that happens, your stopping power takes a real hit, especially on those beloved older Mitsubishi models that have seen their fair share of adventures.
What's Your Mitsubishi Telling You?
• Feeling a bit of a shimmy or shake through the brake pedal or steering wheel when you hit the anchors?
• Hearing any squeals, grinds, or nasty scraping noises when you brake?
• Taking a bit longer to stop, or does the brake pedal feel a bit 'squishy' underfoot?
• Spotting any gnarly scoring, deep grooves, or funny discolouration on the rotor surface?
Will it pass WOF?
Nah, mate, worn or damaged brake rotors are a definite fail for your New Zealand Warrant of Fitness (WOF). They've got to meet minimum thickness specs and be totally free from any dodgy scoring, cracks, or warping to keep you and everyone else safe on the road.

Estimated Time: 1-2 hours per axle
Tools Required: Jack, jack stands, wheel nut wrench, brake caliper socket/spanner, C-clamp or brake caliper piston compressor, torque wrench, wire brush, brake cleaner, safety glasses, gloves.
🛠️ Bob's "Get It Done Right" Companion Checklist
Alright, team! Before you dive into getting those brakes sorted, let's make sure you've got everything you need for a safe and clean job. Bob's always saying a little prep goes a long way!
• Safety First! Grab some sturdy Safety Glasses — you don't want any brake dust or gunk in your eyes. And a good pair of Nitrile Gloves will keep your hands clean and protected from all that brake grime.
• Cleanliness is Key: You'll want some proper Brake Cleaner to blast away carbon dust and any oily residue. A clean surface makes for happy brakes!
• Smooth Operator: Don't forget some anti-seize caliper grease. This keeps things moving freely and quietly, making sure your new rotors and pads work together like a dream.
• Don't Forget the Rust! If those bolts are looking a bit grim, a squirt of Rust Penetrant Spray can be a lifesaver to loosen things up. Trust me on this one!

Bob @ CARFIX is always keen for a yarn to help you figure out exactly what your Mitsubishi needs. Pop over to Bob's Shop for a chat — coffee's on if you're lucky!
Fitment Notes
This particular RDA rotor is a perfect fit for a bunch of Mitsubishi models from the late 80s to early 90s, including the Mirage, Galant, Eterna, and Lancer. But because these old beauties have been around the block a few times, and there might be some subtle variations, it's always smart to double-check the exact specs and measurements against your current rotors. Just ensures a perfect, no-fuss fit.
Bob's Final Word
Always remember, mate, a bit of preventative maintenance goes a long way. Don't let dodgy brakes spoil your cruisy weekend drive. Get 'em sorted with Bob @ CARFIX!

🛠️ Bob's Pro Tip: Do the Job Right!
🧰 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.
