how often should you add fluid .never had the fluid flushed .only acts up in the winter .seem to do it one time in the summer but i added some then i was good for awhile .
Expert:  brownjeff replied 8 years ago.

Should really never have to add. The problem is the seal in the master cylinder or the seal in the slave cylinder is bad. The seal shrinks in cold weather and leaks. In the summer it swells and holds the fluid. It will keep getting worse the longer it goes with out being replaced.

 

Thanks,
