Hey there Mitsubishi owners! If you're dealing with brake issues on your 2017-2021 Mirage or Mirage G4, this A-Premium brake caliper assembly might be exactly what you need. This is for the front left (driver side) and it's a complete assembly that comes with everything ready for installation - including the hardware! The specs are solid: 1.995 inch piston diameter, M10 x 1.0 inlet port, and M7 x 1.0 bleeder port. What I really appreciate is the anti-rust coating that helps extend the life of the caliper - no one wants to replace these things more often than necessary. It's a direct OE replacement that matches reference numbers 345084, 740891, and 4605B003. Installation was pretty straightforward for a brake job, and having all the hardware included saved me a trip to the parts store. The quality feels good - definitely better than some rebuilt calipers I've used in the past. A-Premium backs it with a one-year unlimited mileage guarantee too, which gives me some peace of mind. Just make sure you double-check your vehicle info before ordering to ensure proper fitment. If your Mirage is pulling to one side or you've got sticking brakes, this caliper assembly could solve your problems without breaking the bank. Definitely recommend for DIY mechanics or anyone looking to save on repair costs!
