Well today i got my tires put on and one of the tech guys told me my front passenger side brake caliper has seized up. I had thought that the vibration i was feeling was due to the worn out tires and to my surprise it wasnt . The strange thing is that the vibration would sometimes go away.

Now i'm not too sure what to do. I don't know whether to buy a remanufactured caliper from the local auto parts store, buy a used one, or buy a rebuild kit although i don't have much experience rebuilding the caliper. Also is it fine to just only get the one thats seizing or get both done at the same time as long as its not too expensive that is.

 

Buy a new caliper, you can probably get by with just the one. You'll likely need a new rotor and pads on that side, and those should be done in pairs, so you'll need those for both sides. I'd get stock parts.

Lube the slide pins on all your calipers while you're at it to prevent this in the future.
