will possibly need all brake pads removing and cleaning up also check where pads fit into callipers that they are free and clean so pad can move ,whilst pads are out also check slides/pins /piston etc are free ,would be a good idea to clean up discs as there will be a section where pad was that could be free of heavy rust and may cause pedal to pulsate under braking.if seperate handbrake shoes -they too may need attention!
