I need a rear flex hose that is about 15” long with 1/4” inverted flare for hard line on one end and 1/4” male flare to screw into a junction block on the other. My internet searches didn’t find any sellers that listed the specs down to that level and searching by car makes I didn’t find anything either. Seems everything is 3/16, but my early Ford front system and ‘60 Olds rear are all 1/4”. Speedway doesn’t show anything that I can use. Any suggestions?

    It looks right but I didn’t see anything saying what size threads and stuff. Have you used that one?

    No, I think I used a NAPA part. I just searched rear brake flex line and I found that one. I’ll look through my receipts to see if I can find the NAPA one for you

  5. I think when I was searching for a specific hose, the NAPA site had good detail.

    Thanks, I’ll check. The one in my picture is from a ‘56 Chevy but one end is 3/16 so it’s no help.

    That is an unusual size, maybe you can find an adapter to go from 1/4 to 3/16 so you’ll have more hose choices length wise

    I’ve never ordered online to pickup in store, but you learn something new everyday. I needed CV boots for the wife’s Subaru also and the ones from NAPA were recommended so I ordered the boots and the hose from NAPA. We’ll see how it goes.
    I couldn’t seem to find any specs for the hose on the NAPA website but I’ll know as soon as I see it.
    Thanks a bunch for the tips.

    Look at brake hoses, front and rear, for a '53 to '62 corvette.. I can't find any pics with line sizes,
    but if you find one locally, you could measure it or someone on here may know....

    I’ve got one on order, hoping it will be in sometime today or tomorrow and I can finish this up.
     
  14. RAYBESTOS BH381244 will work and is for 1/4 in brake lines. It is the front brake line for a 52 ford, if you need a little longer the rear for a 52 for is about 2 inches longer with the same ends as the front. It is also the one you need for using F1 brakes on the factory brake line banjo block on a 39 to 48 ford.

    Thanks Jason! I should never have tossed my old Wagner and Echlin catalogs. They had lots of P/Ns, specs, cross references and engineering data. When my buddy retired and closed up his old parts store I grabbed a few catalogs and kept them at my shop for reference. With computers, the internet, and the growth of 1-(800) hot rodding I didn’t think I needed them anymore, so I tossed them when I retired and moved. Thank goodness we have the HAMB.
     
  16. I have all the paper catalogs kept for reference. Grabbed them when they went digital. But, half the time they are at home so I can't help answer Qs posts here.

    BTW, I think I have 4 of those exact NOS hoses I bought off the HAMB years ago. I will dig them out and look. I won't be needing them.

    Bob, I buy these front hoses from NAPA, they fit the early Ford cyls and convert to 3/16 at the frame. For the rear, I use bushings to reduce the rear cyls to 3/16 IF. IMG_9740.JPG

  18. I have some Illustrated guides at home......if they aren't the ones I can look. Never get rid of old paper catalogs, I have regular application guides, but the illustrated guides are better....they have pics and sizes only.

    Sadly sometimes companies online catalogs or e catalogs don't go past the mid 60s, so you can't even find a stock part if you wanted too.....but they still make it IF you have the part number.

    There's a smaller selection of hoses that use a 1/4" hard line but there still around.

  19. First you need to make sure of the thread pitch some GM cars use a 7/16-20 and some use a 7/16-24.

    These are 7/16-24:

    Dorman H35076, Cadillac 1969-61, 7/16-24 male and female, 14.5" long.

    Raybestos BH36792, 17.5" long.

    Dorman H77007 1971-72 Ford Pinto, 7/16-24 male and female, 15.25" long


    These are 7/16-24 and 7/16-20:

    Raybestos BH4497 16.5" long

    Wow, great info, thanks. I’ll check tomorrow but I think my junction block accepts a 7/16 fine thread bolt, like the wheel cylinders.
