Brake fluid and Bleeding???R1_&a_Z28 03-27-2007, 11:55 AM Hey guys, I have a 99 R1 and put new front pads an rotors on. I used DOT 4 brake fluid and bled the brakes. But after a few rides the brake lever is getting mushy and I have to pull it in waaay to far to slow down an stop. Any ideas? Different brake fluid? Just bleed it again? Thanks mickr1 03-27-2007, 02:33 PM Did you completely change the fluid ?? or just add DOT4 to what was in there ?? Prob just needs more bleeding PyRo1509 04-02-2007, 10:40 PM bleed again, make sure all the fittings are tight. I think the problem is that they weren't tight so there was a leak Benocehcap 04-03-2009, 08:34 PM you got air in the lines. Best bet, bleed them again and use a clear tube so you can see the bubbles. keep bleeding until there is no more bubbles in the clear tube.

I just recently changed to steel braided lines and it makes an extreme difference.....

Takes me all of 5 minutes to replace my brake fluid and you can remove a lot more air bubbles because of the speed of the fluid moving through your lines. I found mine on eBay though this guy:

Part number is 639520.
