Swapping Out Your BMW 1 Series Disc Brake Rotors — TRW Style
> Disc brake rotors are a seriously important bit of kit for your BMW 1 Series' braking. Over time, they get worn down by heat, friction, and all the muck on our roads. This means your braking won't be as sharp, which can be risky, especially battling Auckland traffic.
What Clued You In?
• Brakes are making a racket? Squealing or grinding noises.
• Feeling a wobble through the brake pedal.
• Rotors look rough? Scratches, rust, or dings.
• Taking longer to stop than usual.
• Brake pads wearing unevenly.
WOF Woes?
Worn or dodgy brake rotors are a quick way to fail a WOF here in NZ. They've gotta be thick enough and in good nick to pass the test.
DIY or Get a Pro?
Difficulty: 6/10
Time Needed: 2-3 hours per axle
Gear You'll Need: Jack and stands, lug wrench, socket set, torque wrench, brake cleaner, rotor removal tool (maybe).

🛠️ Bob's Pro Tip: Do the Job Right!

• 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.
