Rotors are actually not original, they haven't been original since 2001. The rotors were factory warped and the pads were factory-junk. I have no clue if the current rotors are OEM or not though (how would you know?).It looks like Bunn beat me to this. I had a suspicion the caliper could have been seized. That's strange though that the car did not pull to one side. Seized calipers can be very dangerous.
Pads are shot. Rotors very well be too. Honestly I'd do them while you're in there. If they're original you're probably nearing the point of replacing them anyways, especially on the front.
Historically speaking transverse would be considered "abnormal". FWD is a *relatively* new development but now pretty mainstream. Generally speaking, trucks and truck based SUVs have longitudinal engines, along with RWD sedans, which these days is primarily sports sedans. Cars and car based SUVs go with the fwd/transverse setup.
You'll probably need some metric sockets if you don't have them. You might need a brake key (basically a large Allen wrench fitting), and maybe a brake caliper tool to remove the calipers (draws back Pistons).
The entire car is metric, I also have to replace the valve cover gasket which is held on by atleast a dozen of 10mm bolts. i do have allen wrenches. Being that it's the Driver's side caliper that is what i will replace. Spark Plugs, wires, valve cover gasket, brake pads, caliper and a rotor (possibly) will cost enough as it is. That is assuming I can even GET my grandpa to pay for it.
