Front Break Reservoir

Front Break Reservoir
Hi chaps
I noticed my brake fluid was kinda orange through the front reservoir and upon inspection it was full of thick gloopy gunk ?
I've bled the front brakes and cleaned out the reservoir but have no idea what would have caused this ?
Any ideas ?

I hope this may help answer the question

Brake fluid is hygroscopic, which means it attracts and absorbs water from it's surroundings so any condensation that slowly seeps into the system is being absorbed by the fluid, which causes it to gunk up and for example lowers it's boiling point as well as corrodes the system from within, which are exactly the reasons why brake fluid should be changed regularly, and failing to do so the main cause of corroding and seizing up any moving parts of the system.
I've heard a claim that leaving a fresh bottle of brake fluid uncapped outside overnight makes it absorb enough water from the dew to render it unusable.

If so have I to strip down the calipers ?

Well if your reservoir was full of goo then chances are that there is either corrosion or sludge buildup in the calipers so I suppose it would be a good idea to take a peek inside. Calipers aren't that complicated to service, but in case you didn't know (as many doesn't) brake fluid spills will damage painted surfaces so if you got any on your rims etc wipe it off in a timely manner, doesn't hurt to have some gas or some rubbing alcohol on the rag to get it all out.
