Centric C-TEK 121 Economy Rotors #4893331

I posted about this in the humor section for a different reason, but the Centric 121 C-TEK economy rotors are Centric's equivalent to the infamous "whitebox" economy rotors that are sold by many parts stores.

Normally I do not use whitebox economy rotors, however, this brake job was for a lease return and the driver wanted to minimize their costs. The driver did not mind the rusty appearance from unpainted rotors.

This was the first set of economy rotors that I had used in over two years. After properly cleaning the hub flanges, washing the rotors and installing them with conical washers, I measured the lateral runout values and found the following:

L/F = .001"
R/F = .0015" (after indexing, first try yielded .0025")
L/R = .0005"
R/R = .002"

This particular vehicle (2016 Outback 3.6R) allows a max of .002" so all of the values were within spec. From my past experience, economy rotors typically have .003"-.004" of runout and this was simply too much for most modern vehicles. Resurfacing rotors on a bench lathe usually results in .004"-.007" of runout.

Either I got lucky, or I guess economy rotors have gotten a lot better in the last few years. I was a bit blown away. If economy rotors are consistently this good and the driver is on a budget (can't afford or does not want to pay for premium rotors), then economy rotors have truly become a viable low-cost alternative to resurfacing your old brake rotors. The finish felt reasonably smooth as well, and the pads bedded in fairly quickly. I paired these rotors with Akebono ProACT pads on the front axle and Centric 105 PosiQuiet Ceramic pads on the rear axle.

Also, nthach came by and watched me do this brake job. He's cool.

On a lease return I would've been tempted to put the cheapest pads known to man on that Subaru. You're a better man than me. Nice work and excellent run out numbers for budget parts!

I have used C-TEK rotors(and pads) with good success. I have also use DURAGO rotors as well with the same success. But, this success is also based on the vehicle that they're being installed on. In other words, I had good success with them on a lower end MAZDA and mid level NISSAN. However, I've had even better success with them on a LEXUS. So, it depends on the car & rotor manufacturers spec of the rotors, is how well you'll do with them.

I was thinking the same thing. It's not to be cheap or a sh***y person either, it's just not necessary for someone returning a leased vehicle to do at the end of a lease.

Sure, I understand where you are coming from. But I also will not put my name on a substandard brake job. The owner would have preferred to not do the brakes at all, but the rears were grinding and the fronts were at 1mm.

How did you get involved ? Was this a friend's car that you did in your garage or driveway or do you have a repair shop ? If you use parts specified by the customer and do a proper, quality brake job, I wouldn't consider it "substandard" in any way.

Glad to hear that! I just ordered some DURAGO coated rotors from RA for the hyundai. Going with the centric stoptech street pads 308.15430.

Will see how they do.

Basically the same as Centric Premium but without the coating.

The C-Tek will probably be ok for awhile since you're lucky enough to not have rust (on the east coast, non-coated rotors rust overnight), but they are NOT usable anywhere up north where you get rust.
