99 F350.....My truck has been sitting for probably 2 months occasionally getting fired up. Now that i've got it back on the road Ive got a brakeing problem. My brakes tend to hang up periodically for no apparent reason. My brake pedal makes noises that sounds like a monkey under my dash. While the pedal feels a little different to stop and a little stiffer it still stops alright. I originally thought from reading the forums it might be the hydroboost. But applying more logic to the situation has me thinking it could maybe be some bogus brake fluid or my caliper pins havbe siezed up. Note: I wasnt having a problem before i let the truck sit. What do you guys think????
