hi all
i have got a double flate tool and talked to a few hot rodder guys that i know and even spoke to the guy at better brakes in penrith and was told that a double flare is the right way to do the brake lines, after taking the old lines out the flare on the original lines is apparently called a "bubble flare" that is only the first step of the double flaring process .
my quetion is , if i went ahead and put on the second flare (the recessed part in the centre of the brake line) which i have done, will this leak and should i do the lines again, or will they be alright the way they are?
thanks darren

Don't do it man.

The flare needs to match the receiver in the Caliper or Slave Cylinder. The different types are not compatible.

so do you know where can i get the correct die for the brake lines so i can do them properly

VW use a double flare not a single so it should be fine on a VW. Look into your M/C hole and see what it looks like.

As Mike said it needs to match or it will leak.

thanks
i will double check, its just that i heard that you only need to do the first half of the flaring process and i have done a complete double flare and have been worried i went to far, and you are right we dont want any leaks thats why i am asking the question

Well VW's are a double so they need the 2nd flare alhough my tool does both at once so I am a little ussure why it is a two stage process.

To see if you need a single or double flare, look at the bottom of the hole you're sticking it in. If it looks like it was drilled with an ordinary drill bit, it needs a bubble flare. If it has a raised section in the centre it needs a double flare.
Hope that made sense. If it didn't then ask someone to explain it to you. Don't become a statistic.
