brakes

Look you are going to have to improve your typing skills and make some sentences. Calipers "not releasing" could be old stuck rusty pistons, or something holding pressure. Easy to figure that--just crack a like and see if it's under pressure and if the brake releases. Holding pressure can be swollen hoses, but rare, a BIG CAUSE of that is improper master or set-up where the pushrod is too long and holding the piston part way down past the compensation ports
