2001 town car disc brakes..

Want to do my own brakes and they are shot squealing..do the front brakes have a bleeder valve that I have to open when changing autozone guy spooked me from taking on this chore saying I could jack up the abs??

I was also wanting to next season get 18 rims and decent tires what do you all think about that most places Pep Boys, Sears, etc try to scare me away saying I will blow out the transmision, speedo will be off and ride integrity etc..but I am gunning for that Maurauder type of look that I couldnt afford... money is a matter as she still is sitting in the garage as I await the old Roadmaster to sell..

Interior is close to shot light light gray leather, why in gods name did ford produce cars with light gray and tan interior or most all manufacturer...ebay salvage place has full set from a 2007 town car for 5oo bucks would I be able to get these swapped out I am huge on immaculate interior ..any thoughts or ideas on this or also katzkin covers?//thnks much cjd
