92 Lesabre antilock brakes dont work

Hi Honda accord 2007 , automatic transmission V4 I accidently got the bottom portion of my car bumped and scraped due to a dip in road(i was at very low speed maybe 5 mile or even slow). after coming back home i saw some dripping from bottom of car it is coming from some upper portion of car and is near the radiator pipe. the fluid dripping is non oily and there is no odour to it. after checking it again in 1 hr i saw fuild is still dripping but speed is now slow. I coukld also see some scratching of metal below car but radiator looks gud without any damage.Can anyone suggest me what could be the problem. I need to get to know it ASAP as i have to pick someone from airport tommorow(sunday) and mechanics will be closed on sunday... Any suggestions ...can i take a risk n drive tomm by that car for 70 miles. i dont remember properly but i think my wife told me a month back that there was some drops below the car and ignored it thinking that maybe coolent is overflowing because we have bought this car just 4 months back.

I need to change my upper and lower radiator hoses. Is it possible to do it in a particular sequence to minimize losing antifreeze? If not, I need to have an idea what the total amount of coolant is needed. What is the typical ratio of anti-freeze to water? I have a '95 Nissan Quest XE mini-van. Thanks in advance!!
