hey everybody

im in the middle of doing the ls1 front brake swap ...Im having trouble getting the lt1 lines off...how did you guys do it??and what size wrenches did u use??thanks for your help im taking a little break because im frustrated...

 

You will need metric flare / line wrenches.

Or you will strip the line nuts flats.

Heat will help, Mapp gas or Oxy torch and PB Blaster.

If you round off the nut, you will need to buy a metric ISO bubble flare tool and some new replacement line nuts. Then you have to cut the end off of the line and make a new flare.

Been there done that, be careful or you will make yourself alot more work.

Also if you order replacement line nuts from GM, they will be a different wrench size. Due to the metric size, parts stores will likely have nothing.

Good Luck
