They contracted and the handbrake no longer held the car. Presumably there wasn't enough "spring" in the short cable. MX-5s - at least, Mk1 and Mk2 - have a screw-actuated piston for the rear brakes. My old Mk2 Micra also did - it was a bit of a weird one, with discs all round and ABS. Later cars had ABS, but rear drums. I guess they discovered how to make ABS work despite the self-servo (snatching) action of the cheaper drums.
