If when you drive off it wont release as it used to ,tells me you have a problem with a brake binding.
You need to jack each wheel 1 by 1 get someone to hold and release brake to see which brake is holding.
On release it should free off straight away,if it is binding on release then that wheel or wheels need investigating.
Please do the same applying the handbrake.
