My abs light came on and before I got a chance to look in to it I noticed a puddle of brake fluid under where the master cylinder is. What may be the cause. Was it whatever the abs light was on or was the abs light on cause the master cylinder.I will repair it myself I'm just trying to get a grasp on the problem to try and pin point the original problem. Thanks for any and all advise. I've never changed the master cylinder so if there's anything that would make it easier let me know. Thank you

    The brake booster and m/cylinder should be replaced as a complete unit. You might try youtube to get a visual aide to the process of how to bleed the m/cylinder. It might show the whole process in a video. Once bled and operating good see if the ABS light goes out, if not it will need to be scanned.
