Default Oil stain. Are they from brake or suspension?

I have noticed intermittent oil leak staining my rims. I suspect they are leaked from the calipers.

Anyone think otherwise, could they be from the suspension???

I am planning to buy a service kit for the brake kit and have the seals replaced. That should fix the problem?

Anyway, these pics are 2 different wheels and taken on different day.

That is an unusual leak. Assume it is the brake line to calliper connection.

It's got to be brake fluid. There's nothing else that can leak there.

YUP! touch it, smell it, lick it, but its most likely a small slow brake fluid leak.....seals..


Anyone think otherwise, could they be from the suspension???

Usually when coilover shocks blow, its a black powder substance..

BINGO!

Make note of your fluid level in the reservoir also. Check it periodically to see if it drops...
