Trying to help my son salvage a $1K part for his bike...
Natch, he brings it over after it's effed up, but hey- gotta learn our lessons somehow.
It's the ABS computer, and the aluminum block holds the brake lines with flare fittings.
He was attempting to replace the brake lines, and due to the ridiculously tight access ended up cross-threading several of them.
The worst one he decided to drill it out, and tap for a power coil thread insert. It's the one at bottom-right corner.
The other two have some damage to the male flare fitting end in the block, just from boogering around the brake fittings trying to get them in. Only one looks relatively unscathed.
Told him that he should've tried a bottoming tap to try to chase the threads before going to the threading insert (I've ordered the correct one from McMaster to chase the other two holes, they look salvageable). Never used a threading insert for this type of application, and the bigger problem is he ended up drilling out the male flare fitting completely because he used a drill bit and went too deep with the tip (I've just pulled an end mill out of the cabinet to show him what they are).
Is there any way to save this? Will the threading insert hold up to the pressure, and is there any way to seal this connection given the flare fitting is trashed? Are there any high-temp threadlockers that can be used to create a leak-proof bond guaranteed NOT to fail (these are brake lines, after all...). Could care less if he'll never get it apart again, if he needs to replace the brake lines again he can deal with it at that time.
Even for the other two- one might seal with the flare fitting- the other I'm sure won't. Same deal- any way to seal these connections so that we're not relying on the flared fittings alone?
Thanks in advance for any suggestions...
