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.

QuietCast – The Science Behind the Silence
Bosch QuietCast Brake Rotors utilize vehicle specific castings. The heat flow casting process produces superior G3000, GG20, GG15, and HC (high carbon) casting. Bosch casting provide strength and durability not found in competitive products. While competitors may provide a low cost product, their casting may crack and may have poor durability. Bosch QuietCast is designed to provide consistent, safe, and long lasting performance.

Arrived quick and clean. Straight on. Time will tell, but I am not much of a brake user anyway! Old man slow.

will check durability. I broke my disks with poor quality pads, so I bought discs and pad from this brand..

I've used cheaper rotors where their ads claim they're coated with something to prevent rust, but they still rust up a storm, even here in dry Colorado. These Bosh rotors stay silver in color over time, with no rust. They're my go-to rotors now. Worth the extra cost.

Don’t listen to Amazon people, these things do not fit the rear of the 4Runner limited and likely no post 2009 4Runner. They tapered the rear cylinder that the rotor slides on to and this rotor is not tapered, it’s straight cut. I left a 5 star review because the front ones fit and work great, as well as the ones I put on my wife’s Mazda. Just be warned for 4Runner peoples. I ordered the model 50011237

The rotors seem fine and of good quality. I believe the problem may be with the Amazon confirmed Fit tool. While they appear to go on, they did not seat fully to the hub. I tried 3 different Bosch phone numbers to confirm the fit and ultimately the call was dropped each time. Will call it a loss and go back to OEM.

I've used QuietCast rotors on a few vehicles and have never had anything to complain about. I really like the coating, it looks great, and it holds up. I've had them on one of my vehicles for over five years without any problems.

The dealer charges as much to resurface rotors as it costs to just buy new ones these days. And I find that the Bosch Quiet Cast rotors are much higher quality than the ones you get from an autoparts store that tend to have a much shorter lifespan than the OEM rotors. I've used this brand on my car truck and SUV with good results.

What a great set of rotors for the 4th Gen 4Runner. I replaced the fronts with the quitecast rotors and thought these would do the job on the rear. I was not disappointed.The rust prevention coating is great on these and the rotors feel completely balanced. The inner drums appear to be perfectly round and I don't feel any drag. The pads bedded great and it is apparent that the rotors are true.Because of the rust prevention coating, you will need to coax these onto a new set of parking brake shoes. The coating adds just enough thickness that a mallet might help persuade them on. At this point there is almost no adjustment on the shoes. I recommend driving around and applying the emergency brake to help wear the coating off. Once you've put some miles on the rotors, adjust the shoes according to Toyota recommendations.There is nothing comparable at this price point to these rotors. The high quality of these rotors surprised me when I pulled them out of the box. I will be putting these on any vehicle that I have and will recommend them to friends and family.
