TLDR; Beware, RockAuto can be arbitrary a**holes.
Has anyone had issues with RockAuto return/exchange policy?
I was replacing my front brake components on a 15-year previous 13WL Tundra Brake Upgrade. (BTW, S13WE is better and easier). I referenced a 2005 Tundra as the target vehicle and purchased rebuilt coated 13WL calipers with new brake lines, rotors, and pads.
First, the RH/passenger-side caliper delivered was bare (not coated as ordered). This ended OK since the coating on the other seemed junky anyway, so I painted it.
However, the big deal was that the LH/driver-side caliper dragged and caused a pull when rolling. I noticed on my test drive to seat the pads. By the time I returned, I had the tell-tale smell of burning brake pad and smoke out the left wheel well. Significant rounds of R&I/debug/investigation confirmed the top inboard piston was not retracting.
I contacted RockAuto and they accepted a caliper return, but said I had to pay return shipping and they would pay replacement shipping. ... Not my fault, but OK
The replacement caliper came. But, it had the same issue, just a different one of the 4 pistons. This time, I pulled out my linear micrometer and measured. The bottom outside piston was extended .05" farther than the matching piston on passenger side. With new pads and rotors, this is enough to make contact and drag. The drag was strong enough that I could not turn the wheel by hand.
I contacted RockAuto again. This time they said (email paraphrase) "We don't trust you. Send it back for refund. But, we will not sell you any more brake calipers. Oh, and you pay return shipping again."
After that, I ordered a rebuilt caliper from Amazon. I installed it, and everything is working great. I feel vindicated.
Clearly this was an issue with the remanufactured calipers from RockAuto vendors (specifically Centric). As you may be aware, there is almost no way to contact RockAuto. All this transpired over their Order/Return-Request forms. As much as I wanted to discuss in person, it wasn't possible. In the return form, I only stated the facts. They responded like a**holes and left me in a bad situation.
(I had already returned the initial cores - for this, maybe I am an idiot).
