Anti Lock lamp comes on after a minute or so.

that usually means you have a bad wheel sensor.....first thing make sure all brakes are in good shape... if so then next need to have someone scan for codes. then follow repair steps per code

this could be anything from a bad sensor to moisture in the system. also it could be your ABS control module. a variety of scan tools have an option in it to retrieve ABS codes. then you just look it up and go from there (best bet would be have a shop scan it its cheaper than buying the scan tool and chances are they will tell you based on the code what the problem could be)
