View Full Version : Residue on front disc, how to remove?

So pulled the front wheel off the PD over the weekend. I found a white residue all over the front disc.

I have no idea what it is off but have 2 theories. Either it's from something I rode through on Friday while doing the CCA pre ride like wet clay or something, or it's something thats leeched out of the pads.

Bear in mind I fitted a RF900 caliper to the PD last year which was supplied with used pads. I have no knowledge of the history of the pads except they came from a wrecker so were quite possibly off a wreck.
Whether they have at some time had any sort of brake fluid/oil whatever soaked into them I wouldn't know but I've always though the upgrade didn't give as much improvement as people overseas have claimed.

I am fitting new pads this week and before I do I want to remove the residue properly. Aside from rubbing the disc down with a clean rag is there anything I can use on the disc that will evaporate cleanly and leave no residue and not put my life in danger everytime I use the brakes, or stuff my new pads?

Normally I use Brake cleaner (CRC) failing that some Kerosene in a spray bottle will work well ,I have never had any trouble with it

Water soluble or oil soluble? If it's water soluble (clay),wash it off with water.If it's oil soluble wash it off with brake clean....or stoddard solvent.
