Does anyone know which caliper type 5.5 gens use? Thanks!

 

what do you mean which caliper type. front or rears?

front: one piston disk brake
rear: one piston disk brake with cable type e-brake

 

I wanted to know if the caliper type is floating or non-floating/fixed, number of pistons, Open or closed type, etc. I would like to know both front and rear if they are different. Thanks!

 

yes, they are somewhat different. They are both single-piston. The front I believe is a floating piston (i.e. to compress simply use a U-Clamp). The rear is a threaded piston (i.e. to compress you have to turn the piston in the cylinder.
