How to replace the front brake pads of disc brake on Mazda 3

Repair It Yourself

Dardoor Recommends

  • Perform the replacement of brake pads in a complete set for each axis. This provides effective braking.
  • Do not wash the brake elements with gasoline, diesel fuel or gasoline-based solvents.
  • Observe the safety procedures! when brake pads work, brake dust is formed. Therefore, do not use compressed air and do not inhale dust when cleaning the brake pads.
  • Replace all four pads, if even one of them has got oil or grease. Remember that there is no way to completely clean a pad.
