about how much would a mastercylender cost for my 1996 GT. i need this because i have replaced all disks, pads, and caliper and still my front right and back left brake lock up after about 5 mins of driving.

You can find a reman master for about $40 plus a core fee, unless you bring the old one in right away, and you will also have to reuse the old resevoir. A new master will come with the resevoir, but it is quite a bit more expensive.

ok thx i just found one for 50$ + $30 core.
