The Parking Brake
 

Okay so my neighbor (a mechanic) changed the rear pads for me and the fronts still look okay so I left them on even though I bought all four corners. Didn't do a brake fluid flush. Now, I can pull my parking brake even higher than before I changed my pads. That doesn't make sense, shouldn't it be opposite? Is there a way to adjust this?

It's adjustable on every car I've looked at, but first double check the mechanic's work, and if it all looks okay, ask if he adjusted it and explain what you've noticed.
