Need to re-flare brake fittings?

[Lovin'theSouth]

Hey all,

I need to change out the ABS module on my '14 Silverado 1500.

My question is whether I need to cut and re-flare the lines, where the meet the module, or is it acceptable to clean and re-connect the existing flared ends?

I have not looked very closely, yet, but I imagine that I'd end up having to replace entire lines (if I cut and re-flare); as something is bound to come up short.

Anyone done this job before, and have any other advice, any tricky issues waiting for me? Replacing the module with a pull-out from the junk yard. The pump in my existing part is failing, so I constantly have brake and stabilatrack warnings. If I whack the pump body with a wrench, the trouble clears for a few weeks.

Apologies if this is the wrong forum, btw. 

Kind regards,

R

Oh, should have mentioned--yes, I know that I need to keep my original electronics in (coded to ecu), and I have a tool for ABS bleed.

Shouldn't have to re-flare the lines. Just make sure the threads are clean and they look nice. Don't over tighten the lines going back in and it shouldn't leak.
