Anyone repaired loose threads in late brake calipers? I got mine back from the platers... well, almost all of them, there is a caliper half missing which isn't making me happy. (IMG:style_emoticons/default/mad.gif) The first rebuild went okay until I went to torque the bolts. The threads on these late calipers are now loose enough that even at the 7 lbs initial torque, they slip. Looks like I can get an M7 x 1.0 Time-Sert kit and a set of 20mm deep inserts for about $100. I don't see a problem with doing that but thought I'd throw it to the brain trust to make sure there isn't something I'm missing here.

Well that sucks a part went missing. I don't see any issue with your idea to fix.

We'll see how hard it is to get my claim honored. Looks like I'll be shopping for a rear caliper. (IMG:style_emoticons/default/headbang.gif) |

They left them in the acid too long. I'd be looking for "all" new calipers. I'd think all threads would be suspect and, bleeders are probably toast as well. If it's 914 stuff, it can't drilled to 8x1.25 without poking through the rotor cavity.
Why didn't you send them here to be plated? What do you need? |

I urge you not to install modified brake calipers. Your braking system is your "Big Brother protector"!

If it's 914 stuff, it can't drilled to 8x1.25 without poking through the rotor cavity. Why didn't you send them here to be plated? What do you need? Well, you called it. I just checked the bleeders on the one I rebuilt and they are loose. The bleeders on the other front caliper and both rears seem fine, but of course, the nose from one of the rears is what USPS lost. I actually tried sending all my stuff to Quality Plating in SLC on your suggestion first, but to be perfectly honest, they were horrible to deal with. Wouldn't respond to calls or email so it took almost two months to finally get a quote. That quote was almost $600 for less than 60 lbs. of parts. Even then, I was going to send the calipers down but I got the same dead silence when I asked where they should be sent as they have more than one address. I finally got pissed off and went elsewhere. That worked out just great... NOT. I had a feeling in my gut that having the hardware plated was going to be the worst part of this build. (IMG:style_emoticons/default/sad.gif) As it stands now, it looks like I need both front late bodies or cores and one rear. I think the one complete rear I have is okay as it is an early caliper with through bolts and the bleeder threads seem nice and tight. Ugh!!! |

I’ve had pretty dismal results with most of the plating companies on the east coast. Either no reply or quotes like I’m building a NASA satellite.
I still have a pair of early rear calipers with your name on them so let me know where and when to send them. (IMG:style_emoticons/default/beerchug.gif) |

@bbrock my dad has to rear cores that Mark donated so if he doesn't want them back I can send them to you.. Sorry the plater screwed up your parts.. I have never had anything critical done there so didn't know that was even a possibility..

Mine car had one early and one late rear caliper. I learned the early calipers are a bit more of a PITA to get apart but I didn't see that there would be any functional difference between them. Anyone know if there is any real advantage to late reare calipers? (IMG:style_emoticons/default/confused24.gif) |

(IMG:style_emoticons/default/confused24.gif) If Ben can send mine/his cores, that's even better since I would have to pull the other ones off my parts car that's sitting outside in the mud - it's been raining every afternoon here. |

It's SO close in that fastener journal. Brent, I wasn't sure about the Quality Plating thing, I guess I was thinking small parts etc. We plate calipers for people every week. Quality is VERY weird about plating. They've lost M9x90 Ferrari fasteners before and the reply is basically... "so". (IMG:style_emoticons/default/blink.gif) Have Mark send the stuff here and Jeff can bring some fronts and we'll hook you up. Jeff, let me know when you're heading in so I can grab that snorkel. The car is at the house. Thanks again. |

Thanks all of you!!! This is one of those little disasters that is turning into one of the best parts of this build because of all the generosity and support of this community. I'll start a group PM to coordinate this as I don't want to impose on any of you more than necessary.

(IMG:style_emoticons/default/blink.gif) “ That’s the reply I get at most plating, powder coating, and larger shops for most any Porsche parts. I even sent a set of ‘64 -911 gauges to one of the big name gauge shops and they lost them for 6 months. 232 of those cars made, you can’t just order up replacement gauges. (IMG:style_emoticons/default/headbang.gif) Luckily, Brent is dealing with parts that were made by the thousands. It’s a pain but easily replaceable. |
