My sincerest apologies for the rude title, but I could not find another way to fully and concisely express my contempt towards the applicati on 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.
This was before I installed the anti-rattle clip. The old rotor did not have the set screw installed. Yes, my hands were dirty.
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.
Cheap Pep Boys jack never fails.
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.
It’s RED.
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.

Turns out the torch would have been the right idea

I would recommend cleaning off the threads before reinstalling.

FYI heat does break red loctite grip. https://www.henkel-adhesives.com/us/en/insights/all-insights/blog/how-to-remove-red-threadlocker.html

I believe you, but if it's stupid and it works...

I’d rather deal with red loctite than rust.

I’ll have that stuff exorcised, indeed.

If I had known before going in that the previous loon who worked on these brakes used red Loctite, I'd have applied heat right away.

A fair assessment.

Funny. I’ve always coated brake bolts with anti seize for just this reason lol. Never had one back out when torqued properly either. Plus when you do need to remove them they come right out as there’s no rust either.

I have done the jack-on-a-2-foot-breaker-bar before and lifted the corner of a vehicle off the jack stands. I think it was one of the caliper bracket to spindle bolts on one of my crown vics.

Red locktite is designed to dissolve with heat. Locktite on caliper brackets isn’t uncommon. Many a European car spec it (and sometimes entire bolt replacement) in the repair procedures.

I’m giving the benefit of

“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.”
On my mom’s car years ago , she had gotten her oil changed by a semi-retired mechanic who was also a family friend.
But my mom subsequently asked me to change the oil on her car.
When doing the oil change, I discovered the fucking idiot put threadlocker on the oil filter threads. Fucking idiotic and I had to practically kill myself getting the filter off.
And this was on a 1992 Escort with the CVH engine... meaning the oil change was already hard enough with the filter located at the back of the engine and part way up.
Ended up having to ram a screwdriver through the filter and slowly managed to get the fucking thing off.
I told my mom to never go back to him again.
Also... the same fucking idiot told me I should be using 20W50 oil on my own car in the summer months even though the manual clearly recommended 5W30.

i see no issue with using it on brake bolts.
as i wouldn’t want those bolts coming out when driving along the road.

I’ve broken a breaker bar (ironic) trying to do what you did here. I was trying to remove a bolt to the steering knuckle. All the squats and deadlifts I’ve done in my life couldn’ t budge that thing, so I tried the jack method. Snapped the square insert of the breaker bar. It’s what got me to go buy an impact and a map torch (and a new breaker bar).

Heat loctite until a little wisp of smoke comes out. New Volvo brake parts come with new bolts with thread locker preapplied
