After I drive for a about 10 miles and the truck warms up the breaks start to lock. It fells like I have my foot on the breaks. When I stop and the truck cools down it drives fine until it warms up again

Do you
have the same problem?

HI THIS COULD BE A BAD BRAKE CALIPER OR A BAD RUBBER BRAKE HOSE OR EVEN MASTER CYLINDER. I would try and pin it down to one wheel the one causing the prob will be pretty hot. Then clamp that hose with vise grips or a brake line lock for the mechs. This will pinpoint the location
