My brakes lock up after driving around for awhile. If i let it sit for an hour or 2 it will go back to normal. I had come to the conclusion that it was my brake booster, but i did all the troubleshoot procedures and it passed all of em. I dont think it is my calipers due to them going back to normal after awhile. I am stumped can someone please help me.

The brake pedal gets very hard and it feels like i am towing an 18 wheeler


edit: just replaced the front calipers and went for a drive. Then when it got tight it the rear right side brakes started smoking

the fluid is fine and i didnt think the caliper froze because after sitting after awhile it goes back to normal. and where is the slide pin located?

 

Sometimes the master cylinder can go bad leaking fluid in to the booster causing those problems..the booster seems fine till you take it off and shake it around lol

so do the brakes actually lock up or does the pedal just get hard to push?
