Flared wrenches

Just ordered some of these:

I'm not vouching for their quality as I have not received or used them yet. But I haven't heard anything too bad about them and they can function as flare nut wrenches on many applications, so its worth the $22 + shipping to see if they are in fact useful.

 

I'm new when it comes to dealing with brake lines.

How do flared wrenches work better over the average wrench?

A buddy and I were trying to get the bottom end loose and we were bending the mount. It would budge...

 

a flare nut wrench will encapsulate the nut better. and will help with not stripping the nut. heres a pic, one side is normal the other side is a flare nut wrench.

 

Whatever you do, DO NOT INSTALL A COMPRESSION FITTING IN A BRAKE SYSTEM. There is a reason they are not used from factory, and are not DOT compliant. If you have to cut a line, install a flare nut on each, re-flare, and use a proper coupler made for brake lines.

 

X2 never on brake lines, that's pretty much 1st grade. I was referring (as I stated) to a post about the fittings on the RACK AND PINION and its removal. That fellow seems to have deleted his post.

 

Yeah same deal, high pressure with major consequences, granted you will still have steering if that coupler leaks, but I would rather have something more positive than a compression fitting for my 1500 psi steering system.

 

You can certainly have your preference, that's fine, on the other hand so can I.
That fitting is not your common compression fitting. It is forged steel, specifically designed for use on high pressure carbon steel tube, has internal vibration dampers, positive locking self swaging sleeves and is rated for 4560 psi.

 

Correct. And as a mechanical engineer who specs components for hydraulic systems all the time, I would lose my job spec'ing a compression fitting like that for a high pressure fitting in a critical system. Something like that is meant for a repair, to be replaced correctly asap.

One's life is simply not worth using a compression fitting to me. If Toyota thought compression fittings were suitable for this application, the fitting at the rack would not be a flare fitting with tube nuts.

 

Unless maybe because compression fittings are a one-time-use item, meaning that the lines could not be removed for repair or replacement of the rack, front end components, etc....
