Stripped the Brake Caliper
 
I just installed new 4 piston calipers on my '87 Turbo II, but I ran into a big problem.

I must not have aligned the pre-bent metal brake line correctly into the front right caliper. As a result, I cross threaded it, ruining the threads in the hole.

How can I remedy this? What options, other than special ordering another new caliper do I have?

it depends on how bad you stripped it. If its just a little you might be lucky enough to run a tap through it and get a new steel line.

New calipers? A rebuild on old calipers should be good enough

You may be able to save it by using a tap. You won't have much room to work so a bottoming tap will be required. If that doesn't do the job then a HeliCoil might. However by the time you spend the money on the bottoming tap and/or HeliCoil, you're approaching the cost of a caliper.

Yeah, there isnt too much room to use a tap before you start hitting the flared connection

I don't believe helicoil is the best option for using on a tapered thread for hold brake line pressure, even if they do make one for that. If you can't get a plug tap or bottoming tap, just buy a standard use one, run it into the whole a couple times, take the tap out and put it in a vise, then snap the threads off halfway and grind a new clean end on there, and voila! a new plug tap for your purposes.

It's not a tapered thread.

no taper buddy. Its going to be a regular metric thread, but at the bottom there is a flared connection. If you crossthreaded it real bad, even a bottoming thread might not get all the threads.

Any news calbrio? Worse comes to worse, www.rockauto.com sells them for 50 bucks, or you can take your old caliper and rebuild it for 20 bucks a seal kit

Same thing happened to me. I ended up just buying a new caliper and using mine as a core.

Just make it dirty so they dont inspect the core. Some places might say its not a usable core
