Recently I've been dealing with some bolts that broke when I tried to disassemble part of the brakes on my car.
Soon I'll also have to do the same service on the other side, and I also need to change the front bearing assemblies. I'm concerned that I'll end up with more broken bolts and am looking for advice how to avoid breaking bolts.
The car is 9 years old, 115K miles, in a snowy northern climate with plenty of road salt.
I believe its still on the original front brake calipers & definitely has the original hubs. So the fasteners have had plenty of years exposure to the conditions.
I previously asked another question about dealing with broken bolts (How to remove broken bolt stubs from brake caliper bracket?) so I have good reason to think breaking more is likely.
I'm aware of general methods such as using penetrating oil, applying heat, rocking the fastener back & forth to gradually loosen it - but not really sure which of these methods are best to use vs. what to avoid, or if these could actually make things worse / cause unintended problems.
