Title: Stuck allen head screw on the front brake
Post by: Adept on November 04, 2013, 07:28:34 PM

I have tried to change the brake pads in my front break.
There is an allen screw, holds the pads. This screw is stucked.
I bended an allen key, I tried hammer, WD40, pipewrench, everyting. It is not rusty. How can I move it?

Any solution?

   I use a hex socket driver with a impack screw driver 18 volt or a 3/8 air gun , if you use to much power it will break the bolt,. impack is the best for me,.

never use WD40 on stuck bolts best thing to use is PB Blaster 16-PB Penetrating Catalyst.best in the world if the PB Blaster don't make it move you might want to try heat

Here in hungary we dont't have that  Pb Blaster in  the stores...

How to use the flame? Can I demage the brake valve, or the rubber parts with the heat??

Are you sure you are turning the screws the right direction? just asking... there are penetrating oils available better than wd40, try them first...

I screwed a few beside this, while I changed the oil, and the rear pad... And I wasn't alone (my friend and the repair guy)
