458 Failed at installing stainless steel brake lines on 458 - advice needed

In the pictures it doesnt look so difficult to access, but sometimes you just cant get the right angle... What about removing to screw connecting the upper arm to the wheel hub?

 

I have a set of Gear Wrench flex head flare nut wrenches. Bought them on eBay. Very handy.

Came here to recommend this. Make sure you get flare nut wrenches. You really don’t want to round things off

 

Yeah, brake lines shouldn't be extremely tight so a short flare nut wrench should do the trick.

 

Any of these should work:

Make sure you are using Crowfoot style.

They shouldn't be, but they always are.

It helps to hit them with some WD40

And a careful use of heat. They are always frozen.

 

Using a proper penetrating oil will yield better results than WD40. I usually recommend 50-50 mix of acetone and ATF. Just be careful with it around paint.

Or you can buy really any penetrating oil, but I’d recommend anything other than PB blaster.

 

+1

Acetone + ATF works really well. WD40 is just always what I have handy

This video is really good and also confirms what you are saying (that it does work better):



Really interesting stuff. As mentioned in the video "anything is better than nothing".

Yep, the project farm guy does a great job showing it off! I've been using it for 7-8 years now after an old school mechanic showed me the recipe.

I have a couple bottles in my shop and we use them daily. Important that you get a chemically resistant spray head. These are what we've used for 3-4 years now: https://www.amazon.com/gp/product/B00I0BYFRA/
