The brakes on my 2002 G20 Sport are about ready to be changed... but times are hard and our family is looking to be prudent in our expenditures. Is brake replacement something I can do myself, or do I really need to take the car to a mechanic? I'm good with my hands and have a technical background, but don't know anything about the specifics of brake maintenance. What do you folks say... is this something I can credibly learn to do for myself, or will I be putting my family's safety at risk? Want to do the job right but also spend my money as efficiently as I can.
