Rated 5 out of 5 by Fit great. Big improvement. Replaced some worn and warped rotors. These were great. August 2, 2016
Rated 5 out of 5 by Yes I recommend Great part and I found every thing in just one place August 1, 2016
Rated 4 out of 5 by Good and dependable I have used Prostop rotors, calipers and brake drums exclusively now for over 15 years. I have never had a problem with any of them. July 31, 2016
Rated 5 out of 5 by Rotors for the Buick. I go on line. Buy them, when I get an email that they are ready for pick up. I go to pepboys and they have them waiting for me. No messing around. My cars are back on the road that day. Thanks Pepboys July 31, 2016
Rated 5 out of 5 by easy install! Bought these for my 09 elantra, perfect fit, easy install! Seem well made, but time will tell..! July 26, 2016
Rated 5 out of 5 by Good Value It stops the car. No noise. July 26, 2016
Rated 5 out of 5 by goood product very good product July 26, 2016
Rated 5 out of 5 by Problem solved I had already changed front rotors a couple of months ago and things were fine for a few weeks. Then I started getting a pulsating pedal at any first thought it was the front ones again....WRONG. I found out on a forum that if you feel it in the steering wheel its the front, if you feel it in the pedal it's the rear...ordered online and they were ready to pick up that night a half hour later. Installed next morning and everything is great...I guess after 146,000 miles on Trailblazer they were due! Great price and problem solved. June 20, 2016
Rated 5 out of 5 by FIXED THE PULSATING I replaced a pair of ACDELCO rotors that only lasted a couple of months before pulsating..ordered these online with a discount picked them up early that morning and installed. No pulsating and brakes feel new again,,, March 21, 2016
Rated 5 out of 5 by Great Price and Features I have used these before but switched to forged rotors for durability. Don't need a 50K mile rotor now and these were priced just right. March 17, 2016
Rated 5 out of 5 by Perfect match I got these (31538G) for my 2011 Honda Odyssey. I just put them on, so I can't rate the metallurgical properties. But they are an _exact_ dimensional match to the original equipment ones. UNLIKE THE PHOTO, they DO have the required tapped holes in them (as the OE ones do), and even have one extra. Nothing bad to say about them, so I'll give them 5 stars, but I really won't know how well they wear for a while. February 9, 2016
Rated 4 out of 5 by Perfect fit In the Northeast, road salt eats up brake rotors. The Pepboy's Prostop always fit nice and are more economical than turning the old ones. All rotors are made Made in China so Pepboys is no different than the more expensive ones. The salt eats them all up. November 4, 2015
Rated 5 out of 5 by What I needed The product was as advertised. I was able to pick it up the same day and that was great because I needed to use my car, October 16, 2015
Rated 1 out of 5 by Received warped rotor The rotor I received was warped and unusable. It actually broke my parking break from it not being circular, which caused me to lose money in paying for more parts and labor. October 14, 2015
Rated 4 out of 5 by Best Valu I just needed to get brakes that stop my car and these pads are doing just that. there are no squeaks or any issues. they fit perfectly and are doing exactly what i expected October 12, 2015
Rated 5 out of 5 by ProStop Rotors Replaced all 4 rotors on 2000 Dodge Intrepid. Great price, great product. No complaints. October 12, 2015
Rated 1 out of 5 by Rotor was warped or uneven and shows uneven wear. large portion of the rotor isn't being touched by the pad after a 500 mile check. October 12, 2015
Rated 5 out of 5 by good quality and affordable I bought these rotors to deduce whether my old ones were grinding or not. Box says made in china. Wearing evenly so far, smooth- nice braking. October 7, 2015
Rated 4 out of 5 by Fit & Finish Installation went well. This is not a poorly made part. Durability will be answered later. Price was OK. October 6, 2015
Rated 5 out of 5 by works The local brake shop wanted $200 to change the front brakes. So I bought these with a discount code and put them on myself. October 5, 2015
Rated 2 out of 5 by rusty Bought front and rear rotors for an Audi A3, great price. The car had the original rotors. I never saw rust on the brake surface even if the car sat for days. The composition of the new rotors allows them to rust up very quickly. Every morning the braking surface has rust on them, regardless if it rains or not. In hind sight I would have spent the extra money on oem quality rotors. Oh and check your order if you pick up at the store. The store gave me Pentosin power steering fluid instead of Pentosin brake fluid. October 4, 2015
Rated 5 out of 5 by Great Stoping It stops in a short distance at speeding September 25, 2015
Rated 5 out of 5 by ROTORS GOOD PRICE. JUST HAS EXPECTED. September 18, 2015
Rated 5 out of 5 by Good product, excellent price exact fit, and great price as well. September 12, 2015
Rated 4 out of 5 by fit well hope it lasts My last set of rotors only lasted a couple of years hope this one does better since I replaced caliper as well September 12, 2015
Rated 3 out of 5 by Part works The rotor fit, and I have not had any issues with it yet. September 11, 2015
Rated 1 out of 5 by Not standard fit This review is more about the website description than the part - and I gave a low rating to get attention so others don't make the same mistake. This part shows as an exact fit for my vehicle, however the standard wheel for my truck has 6 lugs, and this part is for a 5 lug wheel. Although (I found afterward) the list does mention it is a 5 lug rotor, the note is small, in a lighter font and not clearly noted. Since 5 lug is not standard, it should not have a bright green checkmark saying it is an exact fit. September 11, 2015
Rated 5 out of 5 by Great item Great item for a great price September 10, 2015
Rated 2 out of 5 by Lackluster fitment No problems with appearance or quality. Fitment, however, needs to be improved on. The machined step on this rotor that is just to the inside of the brake surface area protrudes outward toward the brakes about 1/8" more when compared to the OEM rotors. What this means is the machined step makes contact with the brake pads. In the end, the edge of the brake pads wear against the step but still function. August 30, 2015
Rated 3 out of 5 by works ok it works fine August 30, 2015
