Brake pedal

Just curious if this is normal or if I need to do some r&r. The break pedal on my truck is starting to get a bit wobbly. I was wondering if there is a some bushing or hardwear that needs to be replaced to correct this or is it just like that normally? Something I forgot to mention is if u hit the breaks hard the pedal makes a clunking sound like metal and a bushing slipping past each other and it has a slight catch when sitting at idle pumping the breaks
