There are two types, The uncommon PBR fitted to the later 120y, arguably the Australian assembled models and the tokico type fitted to the 120y, Sunny and 180B. The tokico type have a small brake pad, considerably smaller than the PBR type. I haven't thought hard enough to figure out which is best but the PBR caliper is certainly better looking.

The two share the same bolt pattern. Those pressed caliper brackets are useful because they are a thinner material able to fit to the front of the stub axle assembly and not interfere with the rotor. I have used a bracket made from much thicker material that fits on the reverse side and only to two bolt holes. There is additional work required but nothing too difficult.
