Problem taking out bolts from Brembo Calipers
Ran into a small issue changing the pads on my 04 brembo coupe. Starting from the rears and working to the front. One of the bolts that hold the caliper in place won't budge at all. The first side was pretty easy. Tried using my super human strength. Ended up getting tired and leaving the car. Gonna go at it tomorrow. Wanted to know what i should do to get it off. I don't own air tools. I have an electric impact gum but even the clearance behind the hub aint enough to get to. What should i do to get these bolts off? Any help is needed before i pay someone to do it

Are you changing the rotors also? If not you don't need to pull the calipers off. https://g35driver.com/forums/brakes-...embo-pads.html

PB Blaster is great, and I've used it for 30 years until I found AeroKroil. That stuff really creeps in!
Also, try the poor man's impact hammer. Using a 1/2" socket wrench, use a dead blow hammer, tap the end of the wrench at the farthest point from the socket to get the most amount of force applied to the nut.
Then keep tapping it harder and harder until it breaks loose.
I've use this technique hundreds of times, and always amazed at how easy a stuck bolt/nut breaks loose with a much smaller "instant" impact force than me prying on it with a long cheater bar.
I guess that is why impact wrenches work so well, ha!
"A dead blow hammer is a specialized mallet helpful in minimizing damage to the struck surface and in controlling striking force with minimal rebound from the striking surface. The head of these hammers are commonly hollow and filled with sand or lead shot, which distributes the energy of the strike over a longer period of time."

For fronts I turn the steering wheel until the long cheater pipe clears the fender. For rear I once had to jack the hub up a bit to get an angle on the bolt with an electric impact with several extensions.
Sometimes if you can hit the bolt with a hammer (or a punch), a couple good wacks will knock free some of the material that has bound it up.
Also, the dead blow hammer is a good option. It also makes you feel better by hitting the thing that is making you mad!
