I got my replacement reservoir in the mail so I decided to replace it today. After installed it and bled the brakes I went for a test ride and noticed that I have to press the foot brake further down for it to fully engage. I  was wondering if that's normal ? I don't know if it's in my head as I usually don't focus on my rear brake or try to lock it up.
Thanks for any help or input !

Air in the line. The reservoir is just that - a place for fluid to come from. Any jug and a hose can do that. I only say that to make you aware that it does nothing for the braking - it only is a place for fluid.

Probably a bubble in the master cylinder. Bleed by pumping the foot lever. That will work air out of the master cylinder. Bubble could be in that upward loop of the brake hose to the caliper. Pumping the foot lever when bleeding should take care of it.

make sure you use new crush washers, even if they look good they will not work right.

Thanks for the input ! The screws for my reservoir where melted and stripped I tried to remove them but had no luck and the fluid level was getting low. I came across one on ebay for $7 and bought it. I bled by pumping the brake leaver and refilled the reservoir like 4 times.   

"No crush washers were harmed in the changing of this brake reservoir."

How did you bleed them? Maybe air got sucked back in through the bleeder thingy?
I bleed with a hose to it stuck in a cup of fluid so air can get sucked back in. I also use "speed bleeders" which are a bleeder thingy with a one way valve (I sense a video in the works on this since I have to replace Trey's caliper).

Sorry, I should of stated that the crush washers were not harmed or even touched previously. I removed the reservoir and the hose that connects it to the master cylinder and nothing else. I had a cheap  brake bleeder hose and bottle kit that i connected to the bleeder tip thing. I watched closely and kept bleeding the brakes until i saw no bubbles for several pumps.

Must still be air in there somewhere. Ride for a day then bleed again. Maybe the air is stuck somewhere. Riding should get it where you can bleed it out.

Thanks for the quick replies !! I will bleed the brakes again and see what happens.
