    I decide to put this in the "How to" section

    Below are the pictures i took of the left front brake line from the ABS module to the caliper brake hose.

    So far i have 12" 3/16" bubble flare M10x1.0 thread aka European aka 3/16” Metric line with a male to male union obtained locally at low cost. The partnumber for the union is 45312. The next step is to rent a tube bender and find the time to get this on my car. i will post pictures of all of the tools required for this option.

    The other hard line option requires a tube cutter and bender to attach the line via two union compression couplers and that can work too but it may not be as safe as the first option.

    The third option is to go with the ZZP SS braided hose.

    Its weird there is already a section with stainless steel braid (near ABS module) and then there is a section of plain rubber hose.

    I did find a Regal with the same ABS module but no rubber line at all but someone chopped off the other end [] so i could not use it.

    Here are the pics below...two complete lines (ABS module to LF brake hose) from the boneyard


    ABS module side


    Caliper side


    Step 1 raise the left front turn the wheel to the left. Nice C5 brakes, GMPP sway bar, and GMPP suspension.[8D] Notice the Goodrich line. That line has to be indexed so mark the line and bracket.



    Pictures of the line - 5th brake hose




    Step 2 organize the tools The bender on right was not used it was too wide. Not pictured are the vise grips i used.


    Side by side comparison of 12" line + union and stock brake hose


    Step 3 lets get bending. I bent the ends first and i took more comparison shots. Every car is going to be different IMO so i did not bother taking measurements of the bends




    With every bend i compared it to the line on the car. Which matters more than the spare stock line i had on hand.

    Those white markings or spots i made those while i had the line up against the line on the car for reference on where the bend should start. On the end the spots indicate where the bends begin. The marks in the center was a reference for the center of the final bend.

    The final bend was made near the center and here is what i got.



    BTW if you mess up i learned you can straighten out the line and start over.
    Before


    After


    Final step install union first


    Then brake line

    Day two no leaks but i had to bleed the front brakes b/c the pedal was spongy. The reservoir did not empty so i figured just bleed the left front. Feels like normal again.

    Its possible the hose was put in for ease of assembly. I found a regal w/o the 5th brake hose in the boneyard.
