Howdy,

My front brakes are extra squishy, but firm up after I pump them (sometimes they feel a lot more firm the next day, not sure why).

I bled the brakes yesterday, my fluid was dark amber, like really bad hangover piss (does this really matter? some say it does, some say it doesn't.)

I was hoping this would fix the issue but they still feel squishy and pumping still works.

I'm could there still be air in the system? I attached a hose to the bleeder and did it the old head way, pumping and releasing.

Also what could  be causing air to get into the brakes? I noticed my brake line is REALLY taught (was hard to reconnect the caliper due to the line being so taught after replacing my pads). could the line being taught be allowing air in somewhere? I never see any signs of a leak.

Does anyone know of any aftermarket master cylinder options if the cylinder is bad? The OEM is like 400 bucks.

Thanks everyone

2nd opinion same as first.

95% chance of still having air.

Brake fluid absorbes water and needs to be changed from time to time. Dirty probably because old.

Air will get trapped in the caliper sometimes.  Sometimes I find on bikes you may have to remove the caliper and hold up higher than the master cylinder and bleed it.  Just a small amount of air will give you the squishy feel.

Thanks everyone,

I Will flush them totally once I get time and report back -- it's my daily driver and they are working enough to stop when I need to currently. I just pump them every morning.

The MC cylinder is rebuildable. It's a 30 minute job and the parts are inexpensive. No special tools required, but compressed are makes the piston come out EASY (put a rag over it so it doesn't fly across the room).

Extra line will not affect brake performance. You can use up the extra line by having it pass behind the left side of the streeing stem and then routing back in front to the right. Make sure there isn't any binding as you swing the bars from lock-to-lock.
