so do you think i have calipers thats the same as 4wd sierra cos? like i said earlier only numbers i can find are 310 on the n/s bracket..just trying to clear this up cos i think im gonna have to replace the seals cos they are sticking..do you know of any other cheap but effective brake upgrade i can do seeing as ive limited my choices by drilling the hub?thanks for the info you gave

ps i have only got standard 15 wheels for series1..got some 3dr cossie wheels aswell that i can fit if this helps fit bigger/better brakes
