Can anyone confirm 1991 Explorer uses bubble flares ?
For the fittings into the master cylinder, they are M10 X 1.0 and M12 X 1.0 , but I don't know if they are Bubble flare or something else.
Also, not sure what the original brake line size was.
Can anyone help with either of these ?
I am guessing the lines were the same size, even though the fittings were different.
I think they were 3/16
I don't want to order the wrong line or fittings.
Thanks in advance

Sometimes a Ford dealership parts dept will help and provide the size info you want. I do not recall working on any fords of that year having bubble flare fittings.
I know GM used bubble flares on Buicks. in 1987.
There is an advantage to using a local auto supply store,if you get the wrong part(s) you just bring them back and now you know just what you want. Some may even be able to answer your questions and have the correct parts.

What type of flare did the Ford trucks of that era use ?
Was it a simple inverted flare ? or something more complex ?
Will a bubble flare work in the master cyl even if it used something else ?
I have never worked on brake lines before.
This is all new to me
Thanks

All brake lines were double flare.
You should never mix flares, always reinstall exactly what you removed.
You are aware they use two completely different flaring tools to make them right ?
You can purchase steel lines for brake systems in just about any auto supply store. They come in various lengths and are able to be formed pretty easily. As long as you get the correct fittings, a lot easier to install ready made. If a little too long, just put an extra loop or two where it can't contact any moving parts and make sure they are secured so they can't rub on anthing.

I bought a double flare tool. It looks like you make a bubble flare, than do a regular flare on the bubble flare to make a double flare
Why does it say that the master cyl uses bubble flares ?
Would a bubble flare plug seal the master cyl ?
or does it need to be a double flare plug to seal it ?
I can't find any metric size fittings local.
I need to order them on-line
I think the line is 3/16, but some sites say 3/16 others say 3/8
Any idea what size the lines are ? Do they use different size lines in different parts of the vehicle ?
Thanks again

On all the 1990 Fords I have seen, none used bubble flares. Where did you get that info?
NAPA usually carries the entire mix of assorted brake lines. Some of the metric lines and fittings are colored blue. Std are uncolored..
What you may be seeing, The lines are the same size , but the fittings are different ,. The ports on the master may take 2 different size fitting nuts.

so all 90s Ford's use Double Flares ?
So I should have M12 X 1.0 Double Flare and
M10 X 1.0 Double Flare 3/16 line on the master cylinder?
No vehicles use inverted or bubble flares and bubble or inverted flares will not work on my vehicle
And the fittings should be blue
I got the exploded diagram and I am having trouble figuring out the OEM numbers
The diagram show 2246, 2263, etc.. not the full number
Do you know how to find the whole number ?
I think it is supposed to be 4 characters - something - 2246, so something like 5F7A-xxxxxx-2246
Can you confirm this is correct ?
And how do I know if there are ABS brakes ? And can I bypass them if needed ?
Finally, I have found Bubble Flare Plugs, but not Double Flare Plugs.
Are standard brake line plugs Double Flare ?
Thanks for your help.

It looks like the OEM numbers should start with F75Z
When I look at the OEM part number for the master cyl it is F75Z2140
On the diagram it is only 2140
So, the brake lines, I think are
F75Z2234 , F75Z2264 , F75Z2263, F75Z2268 , and I don't see a number for the line from the ABS to the back junction block
Can anyone confirm these are the correct numbers ?
Thanks

Bill,
I either brought the special parts I needed to the parts dept or store and let the experienced parts guy determine which part # it was or provided the vin # and THEY went from there. You may have trouble getting what you need from Ford because of the age of the vehicle and that is why I suggested you try a place like NAPA. I am no parts dept specialist. I let them pull out what they feel should be the correct part based on their parts experience and if it is wrong , let them figure it out and come up withe the correct part. I know what I need and usually can tell when I see it. If you are trying to order these parts on line , lots of luck. If you need a master cyl , bring your old part with you to the store and compare what is the same or different. The same with the lines and fittings.This can be done once and usually quickly without problems unless they just don't have the part. With something this age you may have a problem getting OEM stuff , .Aftermarket are usually all you can find and sometimes we have to take what we can get.as long as it is the same as the original. Hopefully someone with parts dept experience will come up and offer the benefit of their experience.
