Just checking to see if anyone else has had a similar situation with brake fluid and seal leaks? I completely replaced my complete brake system on my 1972 Camaro, and after doing a "little" research, thought that Dot 5 brake fluid would be a good choice. The reasons I believed since all of my components were new, was that if I had a leak, or while bleeding brakes, the silicon fluid is much easier on paint. One of the things I read was that Dot 5 will not harm your paint like Dot 3 or Dot 4 will. So I filled the system, bled the brakes and all seemed fine.... for 6 months. My Combination valve (brand new) developed a leak on the end seal. So, believing it may have been defective, replaced it. Now my new Combination valve is leaking again, in a different spot. I am suspecting Dot 5 fluid is maybe not compatible, and looking to flush the entire system and start over. Has anyone else used Dot 5, good or bad?
