Yes I have a working e brake and for the records I used z32 2+2 e brake cables.
These cables comes with a grommet on them that fits into a corresponding hole on the s13 sub frame. Then I just route the cable to meet the e brake a small bracket was needed about 2-3 inch piece, of steel not because the cable is short but the mount on the car and the mount on the cable are just that far apert. Cable length is fine.
Parts you will need are"
-z32 brake master cylinder comes in sizes 15/16, 16/16 (or 1 inch), 17/16 (the size I used)
-s13 to z23 conversion brake hoses
-calipers front and rear do research to find what years are iron/alum, 26/30mm
-pads the same regardless of caliper size or material
-Rotors 26mm for 26mm calipers/ 30mm for 30mm calipers
-drill to 4bolt
-z32 2+2 e brake cables left and right
-z32 backing shield plate and e brake assembly (shoes, springs ect)
-if you are staying 4 bolt you need to get the proper anchor bolt for a 4bolt hub. the z32 came with 2 different anchor bolts this is the bolt at the top of the e brake assembly the proper one is thicker and has a more uniform shape.
things to look out for make sure boots on calipers are not ripped and look for signs of a leaking caliper, cheak hose threads and make sure they are not stripped. make sure caliper comes with all pins and clips. If your car is not abs more work is needed. be very careful buying the ebrake assembly its hard to fine the right one, tho the wrong type can be made to fit. make sure your wheels with clear the calipers wheel offset doesn’t matter, spoke design does.
Do not buy drilled rotors because they crack. Make sure you bleed things properly in the right order. Drivers side rear, pass rear, drivers front, pass front then abs rear, abs front. Thats all I can think of right now.
