I'm having trouble finding the Legend dual piston calipers. Everything I see in stock is single piston. What is involved in changing to RL 4 piston? Any advice or other options would be much appreciated! Thanks

 

Ebay has the right side, which you would use on your left side:

The picture is duel piston; however, it only has one piston size in the specs 38.1mm, so
All you have to do is find the left side, which you would use on your right.

 

curious, Zeta; why the Left on the right and the right on the left?

 

Doing that orients the bleeders at the top of the caliper when utilizing them on the 2G CL / TL knuckle.
As a result, though, IIRC'ly it also switches up the leading piston, of the two, to the smaller first. I believe the larger one is supposed to lead? I think the diameter is negligible between the two, like 2mm. It's a small price to pay for not having to replace the warped rotors every 8-10K due to the inadequate factory single pot calipers.

 

Here's an example.

The caliper sat at the rear (2-3o'clock) of the rotor on the Legend knuckle vs the front (9-10o'clock) on CL/ TL knuckle.

Jgood, keep an eye on your local junkyards and you'll run into a Legend that you can check for brake calipers soon enough.

 

I finally found rebuilt Legend calipers. I got a Stop Tech drilled rotor kit with new lines to go with the calipers. It has been a nice improvement!
