My clutch cable arrived today, so I got it installed and added fluid, it took a million pumps of the lever before it started to work, but it is working fine.
I then added fluid to the front brake reservoir and started pumping lever, a million times later it started to stiffen up, but when I stop pumping the lever I hear a kind of gurgling sound from the reservoir and then the lever is loose again. It seems as though air is getting into the reservoir somehow. If I pump it about 5 times it goes stiff again and then it bubbles when I stop. I see no air going into the reservoir from the top. Nothing is leaking out.
I checked the hoses and the reservoir and there are no leaks anywhere. Is it possible air can get in but brake fluid cannot get out?
Bleeding the brakes works normally, meaning there is fluid in the lines, the issue seems to be with the reservoir, but it was working perfectly before I started all of this.
I am going to tighten the cables again in case that is it.
