hi i have a 2000 civic si. and everytime i drive for about 5 min my brakes will all lock up and i cant move anywhere! untill it cools down for like 4 hours then the same thing will happen! ill drive for 5 minutes and the whole system will lock up. any ideas would be greatly aprietiated thankss!

 

sounds like your calipers have been destroyed. put your car on jack stands, get it up to about 20mph and hit the brakes. you will need to either have someone you trust looking at your brake system or either have someone else in the car.
