hey, i just got a 1987 1.6 (i think) sentra carbed, with 89,000 original miles from an old lady and its in super mint condition. the question is for some reason my brakes are sqeeking like a skinny pig and the pads look brand new. and the rotors look good but are mirror like. like they are getting way too hot. i drive about 250-300 highway miles a week do to my job. from what ive read thru the forums search is that these arent vented at all and are prone to getting hot very easy, and the are only made to go around town and not much highway driving. is this tru? and if so would i benifit from getting drilled and slotted rotors? ive searched thru the forums but with no definate answers. thanks for any help
