## Description

Bosch QuietCast is a name you can depend on, with minimum tolerance levels and innovative materials that ensure the very highest quality and brake judder, noise, vibration, and harshness free operation. All QuietCast rotors are factory mill precision balanced, which disperses the weight evenly, and allows for smooth, safe stops with no pedal pulsation. Performance is ensured by OEM style vane configurations that provide more efficient heat dissipation, reduced vibration for quieter operation, and extended rotor life. Aluminum/Zinc coating protection prevents rust and corrosion, extending the life of the rotor while providing a clean look for today's open wheels. OEM style ABS tone rings (on required applications) provide trouble free operation of Antilock Brake and Traction Control systems. Every Bosch QuietCast rotor features an engraved discard thickness, that lets you know when the rotor has reached its useful life, and an “on-the-part” Bosch brand name, so you can be confident you are receiving an authentic Bosch product.

Review: Even though desertcartfit mentions that this will not fit my vehicle, it does. Using BC799 pads with these rotors. Specifically, 6 lug wheels with a 297mm rotor. If you are unsure for your truck, remove the wheel and measure as some opt for Tundra brake mod.
Review: Before replacing the front brake pads on my Mercury Milan, I had my rotors turned at an auto parts store because I could feel some ridges in the surface. When trying out my brakes after reassembling everything, my steering wheel and the front of my car would shake uncontrollably when stopping from even 25 mph. I noticed when I returned from the test drive that the grooves had returned to the rotors -- and they were even worse than before. Tired of wasting time with bad parts, I went with these more expensive Bosch rotors. They didn't disappoint. I swapped out the old ones for these and was relieved when my brakes immediately worked like new. No shaking or squealing, and I'm hoping these ones won't rust out like the last ones. I included a picture of them after installation -- no rust yet.

Actually got this one as a spare, but it's the second one I've bought. Both are heavy, quality parts. The crazy deals I got on Amazon Warehouse Deals made them both too good to pass up.
