Hey,
Im trying to get apart my drum brakes on my rear axle and I can't undo the flathead, recessed screw.
Any tips?
Thanks
Pete

Has the head stripped or can you not apply enough torque?

drill the head off is one way then use a easy out on the shank, or a bigger [wider] flat blade screwdriver.

Impact screwdriver. Buy it, use it (with minimum 2lb hammer). Wonder what all the fuss was for.

... and you can use it for door hinge bolts too

a centre punch and a hammer, then buy some new ones and copper slip them! the problem wont reoccur!
