Ford, ya know, you piss me off sometimes. I’m trying to get all the parts ready to bleed my brakes and the Ford manual doesn’t tell you the proper size wrench you need for the nipple. I tried various sizes on the front passenger brake and determined that 8mm was too small and 10mm was too big, so it had to be 9mm. I go to Home Depot, pick up the wrench, come home and it doesn’t work! I return it, thinking I must need SAE, not metric, and then I find out that it didn’t work because I tested it on the rear! Turns out, you need 9mm for the front and 8mm for the rear. Thanks, Ford!
