So I ordered myself some replacement rear Brembo OE blanks and pads from TireRack for my Outback. Got them today and one of the boxes was a little banged up though I wasn't too worried. So i open up the box and guess what i see... Yes.... Those are the beginnings of drilled holes in my brand new rotor... The other rotor is fine. I thought it was so strange. I would guess at the manufacturing plant they started the cross-drill process on it and for whatever reason stopped and boxed it. Called them up and they are sending out a replacement today overnight. Excellent customer service on TireRack's part.
Brembo doesn't drill the rotors. The holes are cast into them. I recall hearing about some kind of dimple system on some of their models though. It's supposed to help you gauge if the rotor needs replacing or not. Are these the same model rotors? Edit: This rotor isn't damaged, it's a depth gauge on the rotor to gauge the thickness of the rotor. When one of the dimples disappears the rotor is getting thin; when both are gone it's time for a new rotor. Double check the model number on the box.
Yes exact same part # on them. The holes were definitely made by some sort of rotary machine as there are chatter marks on the edges, and one hole is slightly bigger than the other.
I ordered rear brembo rotors for my wrx from tirerack and they look exactly the same as that, both rotors had the two holes in them. I assume they are doing it as a wear indicator so you know when they are too thin. I've been running them for a month now with no problems. I know other mfgs are selling slotted rotors where the depth of the slot indicate the wear limit of the rotor.
What would be the purpose of having one deeper than the other? I would think if they were wear indicators they would have them on both sides of the rotor.
http://www.brembo.com/ENG/AfterMarketBrakes/Products/Productseasycheck.htm I think they only put them on the side of the rotor that is visible when they're installed. Having it on both sides would probably be more accurate, but I'm sure that's why they say "check rotors" after one mark disappears, one mark left isn't a guarantee they're still good. Also, they seem to have a good explanation of this system on their webpage, but I don't remember seeing anything like this that actually came with the rotors. You'd think they could print that graphic on the box or include a sheet with the rotor.
Brembo general service rotors are junk. I use to put them on cars all the time at work. Now they cause noise problems and shake problems. Most of my vendors stopped stocking them. Supposedly they moved there plant to another country and quality control went down the tube.
Ouch... Sorry i was at work and was just glancing, I must have missed your valuable input. It just seems to me the wear on a rotor is too obvious to need a let alone two wear points. I was also thrown off by getting only one. Whats next? Multi-stage squeal tabs on brake pads? Interesting... Good to know. They do say made in Mexico on them... Looking at the boxes again the one does have a small "Easy-Check" logo in the corner. Thanks for the clarification guys
Lol, I don't know if it's that valuable. That would throw me off as well. The only reason I heard about this is because I've been shopping for brake parts all week.
