What would cause my truck to violently vibrate and pull to one side when braking on 1998 Ford Ranger

I slowed to come to a stop in traffic and the truck shook and pulled me to the left rather aggressively.

I think it is actually a problem with the right front brake! The brake caliper/hose or both may need to be replaced.
I appreciate your response and thought it might be that but I'm no expert. Thanks again!
You bet!
