Something I’ve been playing around with, rear disc conversion to compliment the front tracker disc swap I did last year.
Rotors are tracker/ sidekick, callipers are 2013 and up Ford Fusion with integral electric parking brake.
Spacers are required with stock 16” rims, aftermarket may fit.
Currently using stock Mc with residual valve removed. Imgur link has some more details if your interested
