Just purchased a 89 accord lx.. Has a problem with the brakes... front brakes i should say ... There is nearly no pedal to it.. Feels spongy.. as if it had air in line.. I changed the brake pads.... did no good.. also feels as if the driverside front caliper is sticking.. cause i cant push it forward or backward.... Would this be any indication of the mastercylindeer beeing out? or more of a caliper beeing stuck issue? would the caliper cause the pedal to be soft and airy?

Any help would be appreciated
A new honda phenatic.!!
