Brake fluid contamination
#1
Hi Everyone,
After my ride today I noticed my brakes felt spongy. I came back in and tried to burp the fluid to get rid of any air in the fluid. A few air bubbles came out which was really surprising, then the colour of the fluid changed. 

I have cleaned and checked the hose, there isn't any damage to it. Only thing I'm a bit suspicious about is where the hose connects to the caliper. This week I'm going to bleed the brakes fully and see if it solves it.

Has anyone had this happen, because it seems strange that the fluid had become contaminated with no damage to the hose. Is it worth flushing all the oil with new oil or just replace the lever and caliper. Which was my plan in the future.

Thanks.

Tektro HDC-300

Always find the riding in the crap of winter brakes feel feeble and don't bite as well. Worth giving a bleed if they feel spongy though. Fluid in them does look a bit mucky but not that bad. Bad is when it's full dark brown, probably just has a few bubbles formed in it.

I'll give that a go. I'll strip apart my seat post to see if it loosens up.

Got to the bottom of my brake issue, the rubber boot in the lever reservoir has perished. And is was discolouring the fluid. I'm going to replace the whole brakes after pay day.
