Question about 2002 brakes

[kbg4]

Hi,

I was wondering if there are drums or pads/rotors in the rear and what is a typical replacement interval for them?

Thanks

well u can look at them, do they look like rotors or drums
replace them when they have been worn down, if you don't know how to check, take them to a mechanic to look at them, also they have a brake sensor that will tell you in some way, dash light, loud screeching, etc.
