Rear brake line fix (hard lines)

[1slickRED89]

after thoroughly searching for the fix, and not finding it. I found a way to replace the rear hard brake lines. I have a '94 ATX with ABS

two facts:

new lines are not available from the dealer for any ford cars, let alone the SHO.

it's not really possible to make ISO bubble flares at home. that and they are hard to find premade too.

I ended up finding adaptor plugs to turn the M10x1 and M12x1 into standard 3/16" fittings.

parts I needed where four m10x1 adaptors (two under the hood and two at the rear biasing valve), two M12x1 adaptors (both at the rear bias valve) other things needed are five 3/16 line ends , 25' roll of bulk 3/16" brake line (both front-to-rear lines and pass. rear line), one premade 20" line (dirvers rear line, it needs to have the old rear line end installed on it, because it's bigger).

the only tools needed are the standard flaring tool and a small tubing cutter.

the m10 part number is 1442-1 ($3 each x4) and the part number for the M12 is 1446-1 ($5 each x2). I found them at Murry's discount, but I would bet they are available elsewhere as well.

all told, to reaplace all the rear lines cost about $60. pretty cheap considering how important replacing rusty lines are.

adaptors=$22
25' brake line=$21
5 line ends=$10
20" line=$3

Good work, I wonder if stainless tube like that exists? I will have to look into it.
I will copy this thread to the how to section of the forum. Thanks.

nice job. I snapped a brake line end off one day on the SHO...the double flaring tool from AZ served me well enough, but your way sounds alot better for rusty lines.

What type of flares did you make then??

What type of flares did you make then??

For this application, it had to be double flared, u want to get a good set of double flaring tools for this, don't go cheap.

If u know the inner ID for the brake line, try looking athttp://www.mcmaster.com/ starting with part #89895k715, these stainless steel tube lines do exist for a reasonable cost....

 

[Chazenabi]

What about the brake valve where all four tubes go in? How do you tell if thats where the sticking problem is?

why not save yourself alot of adapters and just get m10 ends? (or get a few 8" lines with m10's and just cut them up for the ends?)

the point is, the ends on the sho are ISO bubble flares. To make this flare requires a pricey tool and they are hard to do at home. The adapters mentioned allow you to make a standard double flare and screw normal brake line fittings into the adapters. Not to mention the rears are M12's.

i just did them on my car.
Ford being the a**holes they are dont make anything easy for anyone.
I ended up going to a car quest to get all my lines and bent them all on my own.
You know how most cars just have double flare ends or bubble flares. well ford mixes it up and does some of both. So if you have a flaring tool for both double flare and bubble you can buy bundles of 25 ft line for 17 bucks a bundle. Or you can buy copper line bundles or 25 ft or i believe its 75 bucks but it will never rust out and will stay strong.
I had to go the hard way because i only have a flaring tool for doubles. not bubbles. bought enough individual hard lines all with bubble ends and some conjoiners. So when i got to the point where i needed a double flare i could just cut a bit off and flare it myself. That cost me 80 bucks for all the line.
i took the old lines off the car and layed them on the floor. Taping the new lines and old one together and started bending by hand. taping every couple of inches and on all the bends making sure they where the same or pretty damn close.

Also all the lines are Metric which made them alittle bit harder to find.

Good Luck
Hope this helps.

NEVER use copper for brake lines!

Summit racing has the ISO bubble flare tool for the cheap. OTC brand.

 

[Mrhappytuzi]

Can get the tool from Parts hut for 20 bucks..bubble flare.

 

[HotRodKid]

and just for anyone that missed it , the following statement is WROOOONG:

Or you can buy copper line .. its 75 bucks but it will never rust out and will stay strong.

COPPER is a horrible horrible material to use for brake lines or fuel lines. In some states its actually outlawed. Copper line over any sort of distance will eventually fail due to vibration and rubbing.

but hey, if you want to burst into flames or loose brakes during a panic stop, whatever, just dont do it near me and please only **** yourself in the process
