change the front brakes on my 2004 mustang and was wondering is the rear brakes the same way as the front, meaning do i have to do something about the E brake conn help please!

 

The only different thing you do with the rear brakes is buy or rent a tool that fits on the end of a socket. With the tool you find the grooves that hold in the rear pistons and you twist the piston with the tool and ratchet. It can be annoying if you get a shitty tool.

 

Thats why mine were a pain in the *** to get back in...

As far as the e-brake cable goes, unless you are taking off the caliper you do not need to do anything to it. If you are it is just removing a locking (word that is not coming to my mind that locks it on) and using a vicegrips or pliers to pull it back out of the notch.
