98 Hombre pulls right when braking

I just bought a like-new 98 Hombre! The guy has a company vehicle and kept this thing in the garage for the last 3 years- it looks like showroom and has only 43k miles on it. anyway, the only concern that I have is that when braking it pulls a little to the right. If I drive and take my hands off the wheel it goes straight, it's only when braking and it's every time. I'm wondering if there is air in the left brake line since it's been sitting so long. Any ideas????

sounds like a caliper pin is sticking or is bent.

I would take it to a brake place and have them take it for a spin and see what they think

you mean the pins that the calipers float on? Would it be the side thats pulling, or on the other side?

just replace the whole caliper.
