Ive noticed my break pedal goes almost all the way to the floor before it begins to bring my disco to a stop. if i push it and when it comes back up i push it again its nice a stiff like it use to be. is this a failing master cylinder or could it be that i just need new break lines?

Also currently i have semi metallic break pads on there that need changing not sure if that could be anything. i don't have the money for akibonos but these i have on there now are under warranty and i will get new ones free. The problem i have found is when they get wet they squeal and I'm going on a trail this weekend where they get wet and i don't want the squeal to trigger the amigos. is there anything i can put on the new pads this week like some of the anti squeal paste to prevent that?

Finally i know semi metallics produce a lot of dust what do i need to clean/what do i clean with to prevent the amigos from tripping due to break dust?

 

You may have air in your system, bleed your brakes and you should be fine. (FL, FR, RR, RL Bleed in that order) As for squealing I think there is anti sqeal paste you can buy for your rotors, look at your local parts store and ask Im sure they have some.
