Bolts Impossible to loosen
I need some suggestions. I am trying to change out the front brake pads on my 97 kdx 200. First of all the caliper bolts are not loosening at all. I even snapped an Allen wrench they are so tight. The PB blaster has been no help. The slotted screwdriver bolt plug for the brake pad bolt is not coming off either. Im having no luck here at all. How do I get things off without breaking stuff?

careful with that, I snapped an easy out screw on my rear brake (pin was seized), had to buy a new caliper cuz those bits are impossible to drill (hardened steal)...

Kroil is some of the best stuff I've ever used. Soak & wait 24 hrs.

Thanks for all the suggestions. For now I stopped all work before I smash something. Ill get back at it tomorrow or the next day and try some heat or other method. Right now PB Blaster is sitting in there. Why would someone loctite a bolt that needs to be taken out to change brake pads? Anyway, hopefully I can get this stuff fixed before May 1 HS. Thanks again.

You might try using a heat gun (pick one up at Lowe's or whatever) to do heating. It'll get hot enough to soften the loctite, but unlike a torch, it's pretty hard to damage anything.
Just put the heat gun on "High" and hold it an inch or so from the area on the caliper where the bolt threads are. Heating the bolt head itself doesn't work as well; you need to heat the area where the loctite is.
Heat it for a minute or two, lick your finger and touch the caliper every so often, when the caliper surface sizzles the spit, unscrew the bolt. Repeat for any other bolts. I've used this trick quite a bit, usually works well.

I had to take it to the shop. I was able to drill the plug(3 broken drill bits later) and and get the pin out for the the brake pads but was still not able to get the bolts loose on the caliper after 1 broken allen wrench, pb blaster, and heat. It was time to take it from the professional.
I get the bike back in the morning ready to go.
Thanks to all for the suggestions. I think those bolts were just on there forever. I don't think it was loctite. It was just plain old rust and whatever else causes those bolts to freeze up. They were petrified in there.
