Bob, a bigger question is do we know that the current product is being molded
from the proper rubber compound. That certainly applies to many of the rubber
bits that are used in non-performance applications and I suspect on some of our
engine and transmission mounts that are now being made in unknown foreign
factories.
Rubber compounds are designed for specific applications and heat and fluid
resistance are two of the most critical conditions that rubber development is
focused around. I believe Neoprene is the polymer of choice for brake
components however that's just a starting point. From there a specific compound
is developed using the base polymer. Once the compound is developed testing is
done to what's known as a Line Call out to certify that the compound meets the
design requirements.
I certainly hope that these rebuild kits are still being manufactured by
Girling or Lucas or some other reputable supplier. A no name box would give me
concern. I've seen a few of those with brake parts in them. Not to mention the
assumed liability.
