What type of fittings are used for the stock brake hoses? I want to know what kind of adapters I will need to replace the stock lines with nice stainless braided teflon hose and AN hose ends (Earls Speed-Flex hose and stainless Speed-Seal hose ends).

Both front and rear, and please be sure to include details such as:
diameter,
pitch,
male/female,
convex inverted flare/concave

Application is for an 89 NA GTU RX7. I want to have all the parts I will need before I remove the brake hose- my 7 is my only vehicle. If you have details for other models, include them and maybe this can get archived.

I thought I should add

Banjo Diameter
Banjo Height


Again, all I have to do is take off the hose and measure (need pitch gauge first), but with my previous experiences with doing something for the first time, I am extremely afraid of taking something off and it not going back on, or getting damaged in the process. And brakes are kind of important.

So, is my question badly written, or have all the people who viewed my post never bothered to do anything with the brakes themselves?

I think the problem is that most people didn't fabricate the lines themselves- they (like me) just bought the lines premade, which doesn't require knowing the specifics of fitting sizes- outta the box and on the car, no details needed.

the truth is spoken!!

Yeah, that is kind of what I had figured. Using pre-made lines just doesn't suit me (I always seem to do things the hard way).

Then do it the hard way. Break out the thread pitch gauge and a ruler and find it out yourself.

The reason no one assembles their own brake lines is simple: They are not retarded. Brakes are the most vital part in vehicle safety. If you can't stop, you crash. With your "previous experiences", failure of this part could easily kill someone. Why make a part that is readily available, properly manufactured, and more cost effective? Crimped lines are always more reliable.

Assembling and installing AN lines is not some simple task to be taken lightly, especially if you have never done it before. Routing of the lines to prevent abrasion and avoiding twisting of the hoses is absolutely vital to any kind of reliability. Finding the proper flare fitting (45 degree) with correct nut size to fit the stock brackets will be impossible using the earls product lineup.

The ONLY time to ever make braided stainless lines is for a custom vehicle where manufactured lines or stock lines are not available.

To everybody else: please ignore the below. Normally I would ignore scathcart but the insinuation that I was 'retarded' was amusing.

To scathcart:

It looks like I am going to have to do it the hard way. Just because I seem to end up doing things the hard way doesn't mean I intended to. After I do it the hard way once, the next time is easier and faster. I have to learn sometime. Didn't you read the part about wanting to have replacement parts ready before hand? Haven't you ever gone to remove an old, rusted part and have it break, leaving you screwed (since it is your only form of transportation)?
Premade crimped lines are not "always more reliable". Haven't you heard about aftermarket lines that don't fit, are of poor quality, etc? And AN hardwar is reliable, when properly assembled, or racing teams wouldn't use it, and Carrol Smith wouldn't recommend it. Since I intend to pressure test my lines, they should not be assembled incorrectly without me finding out. Have you even looked at Earl's product line up? They have lots of adapters of all kinds, and at the very worst there are 45 to 37 flare adapters commercially available for hydraulic applications. The only abraison I need to worry about is the ss hose abraiding the rest of the car, not vice versa, and so long as the hose is properly designed. I am not saying it is possible for you to fabricate a working hose line, but I believe I am capable of it.

I would suggest that in the future you make your replies more politely worded. Your tone comes across as insulting, although it would be worse if the content was better. My entire reply is an example of the kind of reply you can expect to recieve.
