I am wondering what the difference is between the stock master and the non abs master? Does anyone know if the abs master have a limiter for the rear circuit in it?

Come and take it
Based on the photos, it just looks like the “f” input is horizontal on both non abs units. Unknown if internals are different though.

usually there is a valve to compensate for the rear drum brakes I believe, but that's in fj40's......
Went through all the pages here and didnt see an exact answer:
I have a 1990 hdj81 RHD (front and rear disc brakes) with no factory abs.
Has anyone deleted the LSPV on this setup? I dont have the tee under the MC, just two lines coming off the MC. Connecting the two lines at the LSPV is the easy part, but Trying to understand where i need to remove that unsused line after that. I believe the line i need to delete from the lspv goes to a tee near the front left wheel bolted to the frame. Can anyone confirm?
I think this non-abs diagram is pretty accurate. Green line is sensing line that goes into a 3-way tee. I guess I have the option to plug the 3rd hole after removing the sense line, or I could purchase a 2-way 90 degree connector.

Just following up on my last post in case anyone needs it down the road:
I successfully deleted my lspv over the weekend on my non-abs truck. My truck is a jdm 80 series so your US model might be different.
There is a tee on the left frame rail just behind the front left wheel/shock area. Theres a rectangle protection plate bolted to the frame to cover the area you need to work on. remove the plate and you'll see the tee in the photo below. Remove the ''left'' line from the tee. This is the sense line you wont be needing that connects to the lspv. I had a very hard time trying to find a ''90 degree'' union that would replace the tee. So instead i opted for an m10x1.0 double/inverted plug to simply cap off that port I didnt need. Link below for the site I used. I placed an order and it shipped the next day.
double/inverted Plug. Be mindful you are clicking the correct option (double, inverted) and not the bubble option.

I have both Advics (Aisin) MCs here, BMT303 and BMT068 with 068 being first gen ABS (93-94) and the 303 being the later model NON ABS. Aisin has superseded most part numbers on the early 1FZs to just two, the 303 for non ABS, and 068 for ABS applications. If you search their online catalog, there are a few others, but they are all in a discontinued status, so just exhausting existing stock.
Internally the valves are the same, They have the same connectors for the warning lights on the outside, and the only external differences are the locations of the brake line ports, and the 068 has a single downward facing port that is plugged with a brass screw. I BELIEVE that was for non US market vehicles, but I can’t remember where I found that info, so consider it suspect at best. I can provide pics if y’all need to see them for whatever reason.
On the later models (95-97), there is only one, it is BMT046. It is also identical mechanically (including the brass screw I mentioned above), but uses a different connector for the fluid level light. I don’t have that one on my bench, but I just replaced it on a friends truck, so I had a chance to look at it closely.

Ok I give up! Can someone help me find a suitable replacement for the "T" fitting after an ABS/LSPV delete? I bled everything today and tightened it all up but it's still leaking. I unscrewed it fully and cleaned everything out, tightened back down but still leaks.
It's leaking from the front fitting.
It's leaking from the front fitting.
In this thread, there should be a part number for a T somewhere. I think the T from the rear axle.
I’ve got one I’ve removed, PM me with offer.

Thank you... I scoured all 14 pages and few other theads as well, but may have missed it. Back into the depths I go.
I'm not real familiar with the types of flared threads out there (10mm, double inverted, bubble etc) so I'm not exactly sure what to look for.
Oh sorry, I could have swore I remembered seeing one. I’ll check around.

I think I found it! So M10x1.0 T fitting? Inverted flare?
Check this thread.
Source for 3 way brake fitting that fits our M10 x 1.0 inverted flare brake lines?
I need a brake line 3 way fitting (maybe called a T fitting?) that fits our 80 series. I tried to order a 90413-10058 (the 3 way fitting that sits under the master cylinder on ABS 80 series) but apparently, those are no longer available. And to be clear, I don't need the bracket that attaches...

Bad news... that part is NLA, according to the 10 dealers I spoke with. Searching for another suitable replacement.
If your cheap and want to save a couple dollars and source the “flying Miata kit” parts yourself:
Valve: 260-8419
Brake union: Napa part# 641-5027
Loctite: 5405
