Thursday I noticed a small amount of brake fluid on my left rear tire. The car is a 69 coupe and had not been driven in a few weeks.I had not pumped the brakes either( My screw up). I removed the tire and pumped the brakes, I could see a drop of fluid after about 5 ms. I have pumped the brakes for the last couple of days and have not seen anymore fluid so far. My question is ,will the fluid swell the o rings and reseat them or do I need to do a caliper rebuild. The car had just had new stainless steel calipers put on it when I purchased it, 4 yrs ago. never any problems before. I also noticed that the brake fluid in the resivoir was cloudy, any reason for that?,I also dont know what brand of brake calipers were installed, no marking on them, I think they are Van Steel brand but If I have to get a rebuild kit, I dont know which one to get. My car came from Arizona and Im in N.C. Help!  Rick d

If you're seeing any brake fluid at all anywhere other than inside the master cylinder, you have a problem. Get that caliper tended to. Whether it to be rebuilt, replaced, a hose replaced, etc. It's simply too important to put off.

If the fluid is cloudy, have the whole system purged of fluid and have it flushed and filled with all fresh fluid. If it's cloudy, it's contaminated.

 Thanks for the reply, Gunslinger,I have already ordered a new caliper and master cylinder from Eklers, When I looked at the master cylinder I saw rust in the bottom of it, so I took it out, I will flush her out good and try again, I ordered me one of those 1 man bleeder vacumn tools, I let you know how she works, Rd

A common mistake is thinking that since you don't drive the car, the brakes don't need attention.  In fact, if you don't drive the car several thousand miles per year, you should bleed the brakes every two or three years.  Driving warms up the fluid and boils out any moisture.  Sitting lets the moisture rot the seals, so no amount of pumping will fix them.  But if you bleed regularly, your breaks should last indefinitely.
