Sierra i am guessing u are doing it on? What year u doing it too?

Not too hard with a kit.

Kits can get from spidertrax,snake racing ($$$$$), or couple other US mobs. if u are going straight for rear sierra discs and keeping the front the same then you will need to purchase locally a pair of discs and rotors.

on mine i am adding an aftermarket brake bias valve as i have too much coming from the rear brakes. i beleive i also have a lazy caliper but will hope to find that as well when doing valve install.

I beleive it is legal to install the valve if it is non adjustable from the drivers seat. mines going in engine bay.

Lines - if u have a WT then u have the single rear line, i have added a T piece into the rear lines and then run new hard lines to each side and connect up with the flexible lines off the calipers.

Cool, I have a 85 NT

ive looked on suzisport and they have a kit, your not wrong about $$$$,

i currently have a set of calipers, re doing seals, pretty paint and stuff.

What model after market brake bias you using? i checked snake they say they are all ilegal in Aus. have you dealt with spidertrax?

I have not dealt with Spidertrax as of yet. but a few have and say they are good.

I am using a willwood one and should get it this week hoping. i ordered it off ebay as the local supplier had a wait of 4 weeks. i beleive u can tweak the original one to like the rear bias of the discs but not too sure and cant seem to find the info at the moment. check on some of the race car sites like vpw and there about 75 + postage or pickup.

Ilegal only id used inside the cab afaik. MART on here has one under a cover so cant be used whilst driving and is approved.

can get u a pick of mine if u want but not much to see apart from the mounting and line runs.

sidenote - on a NT u will have two brake lines running to your rear diff so may be slightly different setup as u will have a hard line running to each rear brake std. should be able to get around using the T piece and maybe the brake valve put in once you have got the kit and calipers installed
