My sincerest apologies for the rude title, but I could not find another way to fully and concisely express my contempt towards the application of red Loctite onto brake part fasteners. See, I’ve been doing the brakes on my XC90, and had few issues removing the last bits of hardware from the front passenger side, only requiring that I stand on the breaker bar to loosen the bolts holding the caliper bracket to the hub. This I could do because I could position the breaker bar to hang underneath the front overhang, allowing me to place my foot on it and apply my substantial mass. I finished that corner yesterday, and proceeded to do the other side.
The other side started easily enough. The anti-rattle clip popped off easily, as did the caliper pins, and, after a bit of leverage to get the piston compressed a bit, so did the caliper. Once I had the pads removed and the piston fully compressed, I put it aside and pulled out the breaker bar and six-point 18mm socket to remove the bracket. The bolts didn’t want to come off, though. Because of the bracket’s position, the bar forced me to pull the handle up, so I couldn’t use the fat man cheat that has saved me from buying impact guns so far. I tried pulling, cursing, pushing, cursing, soaking with Liquid Wrench, cursing, hitting it with a sledgehammer, and cursing, all to no avail. For a while I started to believe that these bolts had reverse threads and I was actually tightening them, but quickly found evidence to the contrary. I left the bolts soaked overnight, and went back to trying the same things expecting a different outcome like some crazy person. I momentarily considered applying heat with my plumber’s torch, but then had a different idea.
Yes, that hydraulic jack is pushing up on the breaker bar to release the lower bracket bolt. It took a not trivial amount of pumping to get the bolt started, and then I used jack again on the 1/2" socket wrench to drive the bolt even more until it was sufficiently loose to remove manually with the wrench. I felt satisfied with this progress and was about to start on the second bolt until I noticed a thing on the just removed bolt.
Look at that shit right there. What kind of deranged mind thinks that a part intended to be removed and reinstalled periodically should get a thicc dollop of red Loctite? The jackass who did this should have his balls clamped with vise-grips tied to a rope and swung from under a bridge. This is the kind of shit that makes wrenching at home so frustrating for a lot of people.
Anyway, that bolt's off. Now I'm sitting through a sprint planning meeting, after which I'll go back and remove the other bolt, swap the rotor, and button everything back up.
