Here's a fun video we did while fixing the upper e-brake cable. We had a knock we also wanted to fix while we had the car up on jack stands. This fixed our problem, and "I DONT HEAR NO KNOCKIN!! Hhahaha!!" We later found the knock and fixed it, as well as the e-brake and windows :) Mazda Miata 1999 NB 1.8L - K&N Intake, Dropped cat, resonator and muffler.
