I need to change the rear brake pads on my car (2004 Hundai Elantra), and it's got ABS. I've done plenty of brake jobs in the past where I'm not worried about most of the job, but I've never done this on a car with ABS, and don't want to break the ABS "stuff" - what do I need to do that's different? Open the bleeder wide open and allow the fluid to bleed out there instead of trying to force it back into the master cylinder? Should I disconnect the battery? Take it to Ruben's neighbor who got his car to quit going whaka whaka pouff pouff?
