Hi guys,

Received the calipers some time ago and today I am starting to upgrade my 300E with 4-piston 400E's calipers. But I have a question.

Both calipers are very dirty so I decided to soak them in diesel fuel to soften the scums a little. Then I noticed my latex gloves kind of melting after being contacting with diesel fuel for a couple of hours. I like to know if the rubber seals around the pistons are damaged for being in diesel for so long ( any latex contents in rubber seal? )

Thanks
