Ok, so I took the Tundra in to a shop that I usually trust to do oil changes and tire rotations... and I mentioned to them that I hit 30K miles, so I requested that they take a look through it for the usual maintenance items.

The shop mentioned to me that the front brake pads were low... now, I normally would trust them in this, except the same guy also told me that I had to replace my front differential oil and transfer case oil, or my warranty could be voided (checked with the Toyota service schedule... he's dead-wrong).

So now my trust in them is shattered... how do I find out if my pads are actually low, and is replacing them something I can do myself? I've worked around cars quite a bit, but I've never touched the brake systems.
