it's a long story but in the process of changing all the brake lines on my 90 cavalier(no ABS) im now at a loss as to where the fronts go and where the rears go at the master. can someone help me out, im pulling my hair out on this one. when you stand next to the drivers side tire looking at the master i have 2 ports close to the firewall, 1 above the other, and 2 ports away from the firewall, and again one on top of the other. PLEASE HELP ME!! On my previous car which had ABS this was labled on the ABS module, so i did not have to worry about this, but now without the ABS i screwed myself. which port location goes to which wheel???
