Does anyone know what, if any, difference there is between the rotors for the front brakes on our TL's with the Brembos or without? I don't have a problem with paying 16 bucks or so more for discs if there is a legitimate reason to do so, but I can't for the life of me figure out what is different. When I look on Rock Auto the discs for the "standard" car are 38 bucks and the Brembo discs are 54. But why? Sure, the picture is different, but, so what? I know that I put "standard" discs on my '05 before I knew "better" four years ago and it's still going strong with the ex driving it. Now that I have a type S, is there really a reason to care about the discs? I bought the disc and pad set from brake motive before I realized that my caliper was seizing. Now that I have fixed that, I need new discs to replace the warped one that I have. The prices on Rock Auto are better than brakemotive but they also the different types. Anyone with any info would be greatly appreciated! Thanks!

 

Last time I read up on rotors, the 6 speed with the Brembos require the 310mm rotor whereas the 5AT required the 300mm so there's that 10mm size difference

 

Get the proper rotors TL-S/brembo spec for your car!

 

I just discovered today that the 300mm (11.8") rotors that many dealers sell as fitting on the Type-S are not the right size. According to this document, the Type-S uses the 310 (12.2") rotors. I have to replace mine (and the jacked-up brake pads) in order to pass Virginia state inspection. Yay!

 

45251-TA6-A00 is the base Rotor part number45251-SEP-A51 is the type S /Brembo one

which dealer do you see selling the wrong rotor and what part number are they listing it under?

 

Advance Auto lists the 300mm DBA2510S Australia T2 Street Series (the only "performance" category rotor offered) and ??mm N1000135225OES "Genuine Brake Disk" as fitting. They also list a couple of 310mm options as fitting as well.

Auto Zone lists 3 Duralast 300mm models as fitting: 31354 , 31275, and 31275. These are shown by AutoZone as specifically for the 5AT, which I have, but they're too small for my car. They have a 310mm Duralast option, but it's shown as for the 6MT. In their performance category, they don't differentiate between 5AT and 6MT. The EBC brakes they list are all 310mm. They don't give the dimensions for their Hawk brand, but HR5317 and HR4936 both refer to "Brembo" in their description.

(These options may be restricted by my selection of a "home" store--I'm not sure.)

I haven't taken the time to dig further, so my use of the term "many" might be overstating things, but I don't doubt that other dealers are selling the 300mm rotors as fitting as well.

I can get the new high performance Akebono 310mm rotors through my mechanic for $81 each and I'll probably be going that route. I'll probably just get the C-Max pads for the lifetime warranty unless someone out there has a good reason not to. I've never had them last for more than a couple of years on any vehicle so the free replacements are nice.

 

You said dealers. I inferred that as Honda/Acura dealers . What you meant to say was probably "some automative stores"

 

Fair enough . . .I'll adjust my terminology in the future. I'm all about clarity in communication!

 

You did bring up a very good point though. I just got some Duralast Gold front rotors and sounds like this may be applicable nevertheless... gonna have to go home and check to make sure they are the proper size. Thanks!!

 

Are you sure that companies that you're looking at do not have a base and Type S option difference? Because whenever I have gone on Autozone, Pep Boys, and others they always have the base and Type S options. And for me I have don't have Type S, but I have a 2006 6 speed. That uses Brembo's as well and there is always an option. Always make sure you get the proper size rotors and pads for your application. Safety is a must with a car.

 

They all seem to include 300mm rotors in the Type S options for some reason. Maybe some 5ATs have the smaller rotors, but mine definitely needs the 310mm variety. . . I'm the 3rd owner so it's possible that the brakes were upgraded to the 6MT version at some point, but I don't have any record of it.

 

Base brakes are quite a bit smaller than the Type S/6 speed. The Type S and 6 speed run the same size rotors. I'm not sure why the 300mm keeps popping up to you.

 

Basically reading between the lines, Autozone's website is wrong.

Try it for yourself to ensure we're not just

 

I ended up ordering the Centric premium rotors and pads, similar to the "preferred" front axle brake kit from xlr8 and saved a few dollars at AutoAnything.

Once they come in I'll put up a few pictures and mention anything I find remarkable.

 

Nice. Let us know how it worked out for you. How much per rotor?

Now I see what you're talking about. They have some rotors listed at 300mm and some at 310mm. That's weird and with that much difference, I would be concerned. But hopefully the ones you got work out for you well. I heard those are a decent brand.

 

Rockauto has the best selection and pricing for brake components.

I got these rotors and pads. They're $55.49 each for the rotors and $43.65 for the set of pads. The rotors are specific to the left and right side of the axle, I assume due to the vane design.

 

You're right--RockAuto could have saved a few dollars. I wondered about the differentiation between left and right side, which they didn't make. I'll allow it could be marketing on the part of AutoAnything

At least Auto Anything had free shipping to make me feel better about it . . .

 

The only reason for there to be a left versus right differentiation would be for slotted rotors.

 

I had to study turbine design back in Naval engineering and I remember enough about it to know that rotational direction is important. I never even thought about the slots on rotors needing similar consideration. That's a good point.

If the vanes were curved, that could be another reason, but I imagine they would make more of a big deal about that in the description. I'll be able to answer that definitively enough once they come in.

 

I got the rotors and pads on. The finish on them is fantastic. It makes me wish I wasn't in a hurry to get them done so I could spend a few minutes detailing the calipers.

Not only did the last knucklehead to work on the brakes out on the wrong rotors, but he cross threaded one of the caliper bolts. I managed to get it off with a breaker bar, but it was a major pain.

Rotor comparison:
Nice heavy e-coating on the unswept areas.

Moar pics! (I can't seem to attach more than one from my phone-I'll put some up later)

 

I'll just put the link to my album: Centric rotors and posi-quiet pads by *.jpg | AcuraZine.com

 

No, slots have nothing to do with it. If the vanes are slanted/directional, then the rotor will be rotational/side specific, but slots don't make any difference.

 

Looks good. You just need to wash up the caliper a little and you should be good.

So you ordered from rock auto?

 

I had already ordered from Auto Anything based on the distinction between left and right rotors on the chance that it made a difference. Rock Auto would have saved me just a few dollars and I was willing to pay a few dollars more. Now I know and can save the next person those few dollars.
