I just changed the brushes on my bosch cordless drill. Now the drill will not start turning consistanly and when it does the speed varies is if I was feathering the trigger. Also the brush/commutator area sparks once and a while. Lastly, the brush area on one side ONLY gets very hot nafter I run it for 10-20 seconds. Any advice help would be appreciated

Thank

Sparking is normal. Do the brushed need to be installed in any particular
direction, up or down or side?

You might want to open it up again and check if a brush lead Or other
wire is shorting out.

A brush that is tight in its holder will cause this problem. Check that
the brushes are sliding easily, and if they are tight, sand them, one
stroke on each side at a time, trying them after every stroke.
