REAR DISKS!! What Brakes Do I have? Stamped 7CLP13S
 

So I bought a beater dx hatch, came with a b16a and rear disks for a grand.

Was trying to adjust the ebrake today (which I still cant figure out if someome wants to explain it to me on a converted car, nut under console wont adjust enough, dunno what to do in the rear)

But the rotors/calipers in the back are probably going to need changing within 5-10k so I thought Id figure out what brake setup I actually had on the car.

The caliper is stamped 7CLP13S and what appears to say NISEN

Any ideas?
