Review on 🚗 Premium Performance Brake Upgrade: Power Stop K4558 Front Z23 Carbon Fiber Brake Pads with Drilled & Slotted Brake Rotors Kit by Ronald Noel

appears to be a quality replacement part. Ease of installation. (It's not that easy to remove old parts! Don't attempt a complete overhaul of an Audi brake system without a PB blaster, hole punch, 3/8" breaker and high impact gloves.) An improvement in brake smoothness immediately after installation noticed. I can't say how long they last, I've only had them for a month. Would I buy again but with my 140,000 miles Q7. I hope I don't have to change the brakes again!
