That is very good advice. I will have to check that out. I have the rebuild kit that I bought from Jim Fredrick, but I just haven't had the inclination to do the job myself. I have done an entire brake job on the car and it stops perfectly. I also used DOT 5 silicone brake fluid so that when my car sits for long periods of time, the hydraulics won't deteriorate.
