    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

      Yeah I wasnt expecting tat!! Anyhow soaked them in ivory snow (wasnt that Marylyn Chambers soap??) and water changed it couple times and the rubber shrunk again and I reinstalled the dust seals. I should get a new set one had a hole through it . Thought Id mention the soap water trick to yo uguys. Later Mike

        Isopropyl alcohol is a better choice for those seals, same with all seals in the brake system. Use 99% stuff.

        I use it to clean all brake parts, don't use the brake clean products at all.

        I would rather trust my bike to a technician that reads the service manual than some backyardigan that THINKS HE KNOWS how to fix things.

            Yes, also for flushing the entire fluid system.
