Mitsubishi Sigma Disc Brake Rotor Replacement — Featuring RDA
> Your Mitsubishi Sigma's disc brake rotors are absolutely vital for safe stopping. Over time, they cop a beating from friction and heat, which sadly means your braking performance can suffer. Keeping your brakes in tip-top shape is especially important for older gems like the Sigma, to keep that original braking feel.
Symptoms That Led You Here
• Squealing or grinding noises when you hit the brakes
• Feeling a vibration or pulsation in the brake pedal
• Your Sigma isn't stopping like it used to
• Seeing scoring, rust, or other damage on the rotor surface
• Your brake pads are wearing unevenly
Will it pass WOF?
Worn or damaged disc brake rotors are a common reason for failing a WOF here in NZ. Your rotors need to be within the minimum thickness and free from damage to pass the test. No one wants that cafe lunch money going to repairs instead.
DIY or Workshop?
Difficulty: 6/10
Estimated Time: 1-2 hours per rotor
Tools Required: Jack and stands, wheel wrench, socket set, torque wrench, brake cleaner, replacement brake pads (recommended)
🛠️ Bob's "Get It Done Right" Companion Checklist
Alright, before you get cracking on those rotors, let's make sure you're sorted with the right gear and know-how for a safe and tidy job. Safety first, always!
• Safety Glasses: Don't want any of that brake dust or rust getting in your eyes. Safety Glasses are a no-brainer.
• Nitrile Gloves: Keep your hands clean and protected from brake fluid and grime. Trust me, you'll thank me later. Grab some heavy-duty Nitrile Gloves.
• Brake Cleaner: This stuff is gold for blasting away brake dust and grease from the new rotors and calipers. Makes everything nice and clean for optimal performance. Brake Cleaner is your best mate here.
• Caliper Grease: A little dab of brake grease on the caliper pins keeps everything smooth and prevents annoying squeals. Worth its weight in gold. Ask for Caliper Grease at the counter.
Expert Recommendation
Worn brake rotors seriously compromise your Sigma's safety. Swapping them out keeps your braking sharp and prevents further wear on other parts. Bob @ CARFIX is always ready to help you find the perfect fit for your Sigma. Come on down to Bob's Shop for a yarn!

• 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.
