    Here's a pic of the LSPV hanging free after my notch.

    You can see the two lines coming from the front of the truck. One is the primary side and the other is the "bonus" going to the front brakes. It ends at a "T" on the frame rail in the passenger wheel well just in front of the firewall.
    If you remove that line, you can either remove the "T" also, or just plug that side of the fitting with a brake line plug.

    thats a good looking setup. ive been looking at how to make a junkyard setup like that. i have the calipers. my 78 has solid 10" rotors. im looking at how i can run an 11" vented rotor. im keepin 14s for a while. also mk3 supra rear brake setups can be modified to work on the pickups. maybe ill use that rear rotor up front on mine. good write up though

    did some napa tech spec crunching and it seems like either the mk3 supra front or rear rotors, which are about $35-40, would probably work on the front of the trucks. the 74-83 trucks had a hub portion that the rotor bolted to the back of. im not sure of the 84-95. but, instead of running a rotor behind the hub, if you used the supra one on top (like when its on the supra) it would give either an 11.88 or 11.65 diameter rotor. they have a taller distance from rotor surface to hat mount, which would help make up for it being on the opposite side of the hub. it would require a new brake caliper bracket, probably need to ditch backing plates (or make ones/modify supras), and it would push the wheel out however far the thickness of the hat flange is. which i couldnt find in the specs. probably like .20-.25. and it would probably require taller lug studs. but its a more cost effective way for a rotor about the same size. might require running a 15 or 16" wheel. unless you milled down some of the meat of the caliper. im still in the measuring stages.

    today ill measure how thick that hat flange is at a napa, and if the caliper will fit under a 14" by removing a little meat from it. it should, it came on 15s in the 4wds with an 11.45" diameter rotor.

    Bare with me here for a min I want to make sure I have this right. My situation is a little complicated as I'm taking a Nissan Hardbody and converting it to the 5 lug yota pattern and upgrading the brakes. You didn't put any part numbers up but one guy did for some rotors.

    From this list - http://www.jegs.com/p/Wilwood/Wilwood-Brake-Components/749349/10002/-1

    Rotor - #160-5844 - http://www.jegs.com/i/Wilwood/950/160-5844/10002/-1

    Hat - #170-1827 - http://www.jegs.com/i/Wilwood/950/170-1827/10002/-1

    The prices are alot higher on the hat than you had talked about in your post from 2 years ago lol.

    For the caliper any 4wd in this year range will work? I just want to make sure I get the right stuff.

    what i read on the 4wd sites somewhere was that there are 2 types of 4wd calipers. one has 4 pistons the same size, one uses a smaller pair and a larger pair. go for the set with 4 of same size.

    yes, I just used the number from a '95 4wd 4runner. It's what I have and what originally spark the idea.

    Ok that's what I thought but on the parts sites I'm not getting a good picture - and you had talked about the buddies truck you had put the FJ front axle in so....

    Also can you confirm that is the right hat -

    # 2.00'' Offset
    # Multi 5 Lug
    # 8 x 7.62'' Bolt Circle

    I know the bolt circle matches the rotor, and the lug pattern but there is another one with a different offset.

    That is the correct info. There is another brake conversion thread that I've posted in too. If the part numbers are not in this one, they are in the other.

    Using a '92 yota front clip on my Datsun project, and am running out of realestate real quick under the hood. What are the feeling towards running a boostless set up on somehitng like this? I know that there are a lot of s-10 guys that do this (some even came with manual brakes).

    I forgot who, I think it was Burnzya on the forum, that recessed the brakebooster behind the firewall itself and made reinforcements.

    I think a boostless brake setup may be a lil "unsafe" in my POV.

    and btw, welcome!

    Probably would be temp until I could afford a hydroboost setup.

    Can I do this upgrade with 12" cobra rotors, or will it only work with that center hub?
    Also assuming this will work on 84-88 front. I'm installing 8.8 rear so need to upgrade fronts
