Caliper bolts

[Tool Pants]

If you backed out a bolt 1/4" and then the rest of the bolt did not back out easily....

Then it will not move with an 18" breaker bar. You can get it out with a 18" breaker bar but you are afraid to pull harder because something is going to get screwed up, like the threads. But they already are.

Not good.

As I said, I see this on the UK Boxster boards because of the stuff on the roads. By the time they finally get the bolt out the aluminum threads are stripped. If they are lucky they can use a thread chaser to clean up the threads and still hold 63 pounds with a new bolt. If they are unlucky then time for another caliper. I don't know if you can heli-coil it.

I do not know why you want to remove the caliper - painting them - rotor replacement. If there is no very good reason to get the bolts out then tighten up the one and let the next owner deal with it. My free advice of the day.

Well, I got the 2 caliper bolts out using a 2' length of pipe on the allen wrench. Not sure if the threads on the wheel carrier are stripped but it looks like the last few threads on the bolts are galled up. i.e. they might have stripped the threads while being backed out due to corrosion. The rest of the threads on the bolt look fine. Guess I won't know the damage until I get the new bolts to try.

Thanks again for the help.

Hi,

As TP suggests, try using a thread chaser to clean up the Caliper threads before using the new bolts. I'm guessing you're gonna be OK. Good Luck!...
