Advice on Swap to Dot 5 - New MC

Thank you AJ,

I did use the proportioning valve from the 72 Dart as well. A mustang flying in a residential area took 'er out. Right in the DS front bumper. I had that Dart for about 14 years! So I swapped everything from it into the Duster pretty much, "EXCEPT THE BRAKE LINES"!!! Yikes!!! You know. As much as new MC, WC's, and Dot 5 fluid costs, Yeah, I should probably make it an overhaul and change out the lines. As for the stopping power, it hasn't been the greatest, but it does stop. The problem exists if I were to drive it in the City, or on the highway in the city, everyone else can stop 3x faster than I can. So I stay out of the cities all together. No need to drive there anyway, that's what the daily driver is for. Coming off the highway, 2nd slows me down and I put 'er in neutral when coming to a complete stop if I need to.

Good spotting on the proportioning valve. I rebuilt the Duster about 12 years ago and forgot about that little but crucial part to the braking system. I do have much larger/taller tires on the rear, 15's and 14's on the front that are normal size. So I think your right about that making it equal out a bit. I will have to pay attention to the difference in braking when I go to a lower profile back tire, 50's racing radials. But I do think I should change out the proportioning valve when I change out the lines. Now that I think about it, that may be a time when I switch to discs. I suppose if I get my discs system from a mfg they would have the right proportioning valve to go with it.

I'm just hoping like crazy that the front and rear connections to the MC fit. It is a beauty!
