Hey H4 not sure if ya noticed, there are no frt Drums on a 07 Forman 500.
That is a Very good explaination though if you have frt drum breaks
If you have to pump the Frt Disc brakes then there is air in the lines witch will also give you a spongy feel OR Like the above post

thumbup: James) if the wheel bearings are loose and the brake rotor is moving back and forth it will push the caliper pistons back into there bore and cause you to have to pump it to bring the pads out to the rotors. There are NO adjustments on disc brakes they adjust out as the pad wears. How it the pad material ?
Hope this helped.
