19mm caliper bolts

[Andy348]

I'm trying to remove the 19mm caliper bolts so I can change my rotors. These damn things really do not want to move.

I've tried using a torch, WD40, a BFH and a breaker bar. Is there something I'm missing or are these things just damn hard to get off?

Yeah they can be damn hard to get off. My solution was to take it to a small shop and have them remove the bolts w/ an impact wrench, put some anti seize on the threads and put them back in. Then drive home and take them off myself. They only charged me $10.

Shouldnt put anti seize on those, as you should actually be putting thread locker on at install.

they can be on there pretty tight. Ive never had that much of an issue with a breaker bar and an 18" pipe for leverage.

There's no reason to use thread locker on those bolts. Just tighten them to spec torque.

I have always put a minute amount of blue thread lock on after having one back out on me that was 5 lbs over spec when tightened. Had another loosen up before that. But thats what I do on my cars, and I still never have any issue removing them even 3 years later.
