19mm 3/4 is same same iirc. The 18mm doesn't go on and the 3/4 feels tighter than the 19mm View Quote View All Quotes View All Quotes Quoted:

Make sure you use the correct wrench though (metric), the last thing you want to do is strip the head of that bolt with a standard wrench. Also, 18 mm bolt heads are an American thing, everyone else seems to use 17 or 19. My metric socket and wrench sets from the 80's didn't have 18 mm in them. |

The caliper bolts are torqued to 180lbft on my F150. Took a big impact and heat to get them loose. Have you checked the torque spec for yours? I doubt anywhere near that but just curious. View Quote |

Non impact socket. Non impact extension.
Weak impact. If you are in metro Detroit, swing by. I’ll bust it loose with an adult impact. |

You didn’t mention penetrating oil, but I’m sure you’ve probably been using it. If not, Kroil is best if you can find it, PB blaster is the best I’ve found next to Kroil.
Next start with heat and try it at least a few times. Then move on to hammer shocking it (2lb hand sledge is one of my favorite tools). If all the above hasn’t worked then the last step is a 4 foot pipe. I’ve found the pipe should always be last as it either breaks it loose or shears the head off. That bolt probably wasn’t over torqued, more likely it’s seized due to weather and brake heat over time. I snapped the bolts for the ball joints on my old STi that were seriously seized to the point I don’t think ANYTHING would have gotten them out. I snapped the head off the first one within 5 minutes and that was only using a 18” cheater pipe. Knowing the second bolt would probably break and be a bitch to drill out I tried everything over a week (5 different oils, tons of heat, shock vibrations, even a freezing spray). I ended up throwing the 4 foot pipe on the 2nd bolt and it still snapped right off anyway. I ended up having to drill both bolts out and neither one ever caught, even with a few MMs left. |

Most caliper to steering knuckle bolts require 100lbft. That's more than most 3/8 tools will do

View Quote I had to take unthread a galvanized nipple in a well one time, out of a brass 90 or something, the nipple looked like a clump of rust. Probably been there 20 years. WD40 and a 24” wrench did me no good. Sprayed some kroil, probably could’ve taken that bitch out with my fingers. |

There is no way a caliper bolt on a Honda is too tight for a proper impact to remove. You might want to consider an upgrade there in the future.
For now, turn the steering wheel until you can access the caliper bolt easier, put a short socket on a big breaker bar (go 1/2" drive especially if you're using chinese) and use a cheater pipe if you have to. If things still feel a little too hairy take a MAP torch and heat the area around where the bolt threads in for a little bit, then try breaking it loose again. Like @Jason280 said heat, corrosion, and thread locker will make those bolts stubborn. |

I left pb blaster on it for an hour or so with a salamander pointed at it. They came off this time.... With a 4' cheater. The left one was the worst even though it's the cleanest |

Ya know if that was a Snap-on extension they would replace it for free.... Just saying.

After I sheared the drive off my 1/2 snap on breaker bar, I got a 1200 ft lb chordless impact wrench. Now I fear no bolt

Been working in shops since I was 6..
Cheater bars and half inch impact wrenches are the shizzle. A bit of heat helps sometimes too.. Ed |

Quoted: No shit. I used impact with impact. I sheared the 3/8 with a 3/8 breaker bar. View Quote Speedaire Compressor I got lucky and did some horse trading to get it about 7 years ago and it is a heavy duty that came out of a commercial environment. That said, you can get a nice 3 or 4 HP model that will do most things that a car or truck requires at HF and they hold up quite well and work great for a home environment. I tried the battery operated impacts and working on the plow truck or the tractor, I broke them, so I have given up on them. I will have to check, I had a 3/8? chrome plated 6" extension I spun with a breaker bar that looked like a candy cane a few years ago, it didn't break, it just twisted and I go pissed and twisted it as far as I could go before I stopped.!

impact rated is going to work better with a breaker bar still, just because people talk about using them with an impact, doesn't mean it doesn't hold equally true with a breaker bar.
two different types of steel. non impact stuff is brittle as you found out. |
