I'll budge in with my problem:

My pads and rotors are stock @45k. The pads seem like they have some more life to them but my braking is horrible. The brakes either suck or lock up the tires. I wanted to know if it is the brake fluid that needs replacing or do the brakes need to be replaced. How hard is changing/bleeding the brake fluid? Can I do it with common tools?

Also do the rear drums need any work or are those almost bullet proof?

If I do decide to change I was thinking EBC grooved rotors and EBC Green Stuff pads. I would like to get the AEM or other brand big brake kit but I don't think they have them for the i4's.
