Brakes sticking with Line-Loc

Took the 73 Dart Sport out for a country cruise the other day and noticed my brake peddle sticking alittle,so I pumped a couple times and it went away.I use my line-loc at the track and am wondering if I have air in the line?Should I just re-bleed the system?(which I,ll do anyway)What would cause this problem?Any help?Thanks.


P.S I,d like to get this fixed a.s.a.p as I,m going T&T Wed. night.
