I agree with the others. I have no troubles with any of my drum brake equipped vehicles and if properly set up, you won't either.
You don't know the condition of the brakes on that truck. I've seen people do some
scary things when it comes to brakes! Some people just shouldn't do auto repairs!!!
First thing I do when I buy a new toy (other than clean it up) is to go over the brake system. Most times, I find alot of problems.
