Swapping Out Your BMW's Disc Brake Rotors — With DBA
> Your BMW's disc brake rotors are absolutely key to good braking. They wear down over time from all the friction, especially if you drive it like you stole it! Dodgy rotors mean dodgy braking, and that's never a good idea.
What Clued You In?
• Brake pedal feels like it's pulsing or vibrating
• Brakes are squealing like a stuck pig or grinding
• Taking longer to stop than usual
• Rotors look scored or generally buggered
• Brake pads wearing unevenly
WOF Worthy?
Worn or damaged brake rotors are a surefire way to fail a WOF here in NZ. They gotta be above the minimum thickness and without any major cracks or damage.

Difficulty: 6/10
Time Needed: 2-3 hours per axle
Gear You'll Need: Jack and stands (never get under a car supported only by a jack!), wheel wrench, socket set, torque wrench, brake cleaner, caliper tool (maybe)
