Stripped caliper/brake line bolt-how to fix..??

[Rickkins]

Hi guys. So, there we were, installing a 'new' rear caliper, but the damn threads stripped. The caliper was new, but they refurb them and the hole was buggered up right at the top. We managed to finally get it in, but the damage was done, and it leaked. What can we do to fix this...??

The bolt, which was fine, is now damaged too.

Thanks.

Is this the hole for the brake line? If so you'll probably need another caliper. If you run a tap in it, the metal flakes will end up inside the caliper. You'll need a new bolt also.

I'm hearing about something called "helicoil"... is that a viable solution...??

Thanks.

Step 1 of installing a helicoil requires running a tap into the stripped hole and probably getting metal chips inside the caliper like gmtech1 said. Unless you can prove it was previously damaged you'll need to buy another new caliper,bolt and any metal sealing gaskets for the bolt. Chalk it up to experience and move on.
Sometimes it helps to mount the caliper loosely so it can be moved around some then start that banjo bolt though the line and thread it into the caliper using new sealing gaskets until lightly seated. If it binds or gets hard to turn, stop, somethings wrong. Take it off and examine it. Once its seated properly tighten up the caliper mounting bolts,torque 'em to spec, then the line to spec. Then go through the bleeding process. Then check for leaks. HTH

Ok, thanks guys. I guess we'll err on the side of safety and change the caliper.

Thanks.

So, we were lucky enough to have the parts supply store replace the caliper for free. We replaced the banjo bolt..... which means we also had to replace part of the brake line, because it would be too damned easy to make the banjo blot replaceable just by itself... oh no....

Anyhoo, all's well that ends well...

Thanks

Great! Glad you got it taken care of!
