These old threads just keep reappearing
Because the same issues keep coming up.
The biggest problem with using compression fittings on a brake system (other than the fact they're dangerous) is insurance. If an accident occurs and your insurance company finds out compression fittings were used on the brake system you'll be SOL. Won't even matter if the brakes were the cause of the accident or not.
