I'm installing my ABS delete kit/proportioning valve/line lock. I have to cut and flare the stock lines to hook up to the new lines. The stock lines consist of two small lines for the front and one slightly larger for the rear. I got the front done no problem, but when doing some "practice" flares on a piece of scrap stock line, the larger line just slips in the flaring tool clamp. I tried using the next size smaller hole on the tool, but it's too small for the line.

Any tips? Should I try a different flaring tool?

Flaring looks easy in theory but when you actually do it...P.I.T.A.!!!

You have to tighten the flaring tool beyond belief so the tube doesn't slip in the tool. I used a unit from harbour tools. Flaring is why my 65's brakejob took 40 hours to complete.

Yeah, I tightened the clamp as far as I could, even used a wrench on the wing nuts, still slips. I tightened the nut closest to the line first, like the directions say. I'm very irritated. I won't have time to work on it again now for a week.

Your other option is to buy brake line with ends on it already. Measure the line needed and if your lucky you can find the right lenght and bend the lines...which is a whole nother irritating process.

I put the tool in my vise and banged it with a hammer to tighten the wing nuts. It has to be that tight.

Aron,
What brand is the flaring tool? The reason I ask is because a cheap flaring tool usually performs relative to the purchase price. I never have to tighten mine down that much to hold the lines. We do lots of custom brake and fuel hard line installs and have never had a problem with the flaring tool...it's a Blue Point/Snap-On and I've had it for 20 years. Flaring tools are one of those things that you definitely get what you pay for. Let me know if I can help.

double check your line and make sure your not using metric steel line in a standard brake flaring tool or vice versa.


its very easy to confuse the two and they are often mismarked at a lot of local supply houses.

The flaring tool came with the kit, so I'm sure it's a cheapo Chinese or Thai tool. I already considered that it may be a metric line, and went to the hardware store to get a metric tool, but they didn't have one. I'm gonna have to look around at auto parts stores. :(
