How To: Acura Legend GS Sedan Dual Piston Caliper Swap

[Jeff Likes Bagels]

I think it is VHT that I used. I had to buy it online from Amazon because I couldn't get it anywhere locally.

Time to start price shopping and making purchases.  Money in, money out.

Its usually money out 2x money in though isn't it.

So for my i4, if I order aftermarket rotors for the Legend LS coupe or the Legend GS sedan, are they the same spec or different?

And you still need to reverse the sides of the calipers on the i4 (i.e. left GS caliper installed on the right, and right GS caliper installed on the left) because of a damn bleeder screw??

Sometimes, yeh.  Mike, throw on a steelie for me and let me know if it clears the calipers lol.

The part numbers are the same for the LS coupe and GS sedan for the rotors.  Regardless of what you get it for, it will be the same thing.

gs brake pads and 04 6spd pads look very similar, gs pads have some kinda notches on top of brake pads(edges)
legend brake pads on right(ebc green) and 6spd on left.
since brakets that hold the caliper are the same i dont see why you can use accord brake pads for it. just have to check clearance of those tabs

Don't have those. Tim probably used steelies over his GS calipers.

I actually don't remember if I did or not.  Honestly, I highly doubt the steelies won't clear.  The calipers are about the same size.  Remember, the pistons for the caliper are on the inside of your wheel.  Any additional bulk on the caliper because of the additional piston would not have anything that would get in it's way.

^ OK.

Can someone answer the question above about needing to reverse the calipers?  Also, there seems to be a lot of speculation about which rotors (v6, 6speed, legend, etc.) work with which brackets and pads.  I hate overthinking, so can someone clarify which combination is the right one for an i4 sedan?  Gracias.

Yes, you need to flip the calipers so that the bleeder valve is on top.

As far as what rotors to get. If you have an i4, your easiest option is to get Legend rotors, and stick with the Legend caliper bracket.

For v6 accords, you can also get the v6 6mt coupe caliper bracket and v6 6mt rotors. Whether or not this solution would work on an i4, I don't know. I was close to trying it, but I didn't want to take the risk, so I went with the original option.

I merged your new topic Dave.  You're asking a lot of questions pertaining to one topic in multiple threads.  It's better to have all of that information in one thread for people to reference, instead of strewn across multiple threads.

Legend and V6 Brackets are the same so I assume that you can use the rotors from any. I used rotors for a V6 auto, the rotors from the 6 speed are a little bigger. Tim successfully installed the same exact calipers you have with legend rotors so why not imitate his set up?

[timot_one]

Here's the thing.  You can't use the V6 rotors on an i4 because the hub is different and the caliper placement isn't the same.  When I tested with i4 Accord rotors, they were the right diameter, but the wrong offset, so the pads were only touching one side of the rotor.  When I tested the V6 Accord rotors, they were the right offset, but wrong diameter, so the rotor hit the caliper.  I found out what the working offset and diameter was on each rotor, and plugged that into Brembo's look up tool and came up with the Legend LS Coupe rotors.  That's why I used them.  I test fit them and they worked perfectly.  End of story.  No need to question it, just do what works.  Figure out what rotors and pads you want, get them for the Legend GS and call it a day.  It's really not as complicated as you've made it out to be.
