Doing pads and rotors on my 17, and the front caliper bracket bolts won't budge. I've hosed them down with Blaster PB lubricant, but can't get them to budge.

Any tips or tricks would be greatly appreciated right now.

Thanks!

 

they have threadlock on them

 

MAPP/Propane torch. Needs heat

 

Turn harder. They’ll come loose. Heat is a last resort with brake components.

 

Also need to clean the threads and reapply new threadlock or replace the hardware.

 

Yep, they have threadlocker and are torqued to something like 160 ft lbs.
First time off from the factory will beat you up pretty good.
last time I did this, I used a long handle 1/2 '' drive ratchet and struck the handle with a block of wood( a chunk of 4x6 cut off at about 5 inches).
Was still a bastard, but saves your hands from getting mashed all to hell from hitting the ratchet handle with your palm( ask me how I know ).

 

Heat, and Impact Gun preferably 1/2 go reverse and forward a bit it will loosen up

 

Personally, I'd stay away from heat and impact on brake parts. Just use a long breaker bar and apply consistent pressure. Don't strike it!

 

I used an old trampoline pipe over the breaker bar for some SERIOUS leverage. No heat or hammers needed!

 

What he said. Penetrant and the longest pipe you have that fits over the breaker bar. I've used a 6' piece of 2" fence piping and steady pressure for tough bolts.. It works.
