Im a college student low on money living on my own and l drive a 2003 infiniti g35 but l am fairly certain l need new break pads and rotors and drums and ive heard it can be expeensive.. does any one have information

well is easy to do brakes & much cheaper than any shop so learn how will save u money & time. but best u call a few shops.. or find someone that will do it for u my wife does her brakes.. shop a around brake jobs run like 89 bucks & up. depending on if u need parts besides pads. call autozone & u can get price on parts. u can what a video on how its done or read how its done & if its just pads u can replace them ur self for like 30 bucks if the rotors need turning better to have a shop do it

The break pads will probably be around $40 for a set, that will cover 2 of ur tires. And most break pads for all types of regular sized cars & trucks cost about that.
The rotors will average from $25 - $50 a piece depending on the type of car. ( My dad said the rotors for his truck where $25 a piece because the size his 1994 Chevy Silverodo uses r common for most vehicles of normal size) but u car may be a little more because it is made in Europe.
The drums for his truck where $50 a peace but can go up to $100 a piece.
Now the service price is not going to be good its going to cost u about $600 or $700 at least.

About $400 front and back assuming you don`t need rotors.

One place you can use to do price checking on car repairs is in Driverside.com - you can drill down to specific cars like a infiniti sedan. They are still in beta but they have a ton of data on what car parts and repairs should cost.
