Front calliper difference

[Glenyboy]

Is there any difference in the a-arm and j-arm calliper?

I.e. mounting holes, or the internals?

 

I have a 2002 in the Yamaha shop, the pistons on the brakes are scored and the brakes feel like mush. So they ordered in the rebuild kit, and it doesn’t resemble the internals on mine.

 

They had some other banshee brakes laying around, and they don’t line up with mounting holes on the bike.

 

Any ideas?

I’ve asked them to send me some pictures

Yes they are different. J-arm/a-arm spindles and calipers must be changed as a set.
