[QUOTE="Jasle, post: 656102, member: 26675"] I'd be interested in if the fluid was the correct type but if you used say dot 3 instead of dot 4 the main difference is the wet and dry boiling temp. Dot 3 boils at a lower temp. This usually leads to a mushy lever. This is due to the fluid boiling off water that has been absorbed and then the boiled water causes a vapor which is compressable. Try riding some practice and wait until the problem surfaces. Then pull off while the disc is grabbing and open the bleeder. If fluids squirts out instead of dribbles then you could have a brake line "check valving" you might need to replace the hose. Also I have seen this exact problem when someone put some oil in the brake fluid resivoir. The petroleum based oil attacks the rubber lines and causes them to expand. Lever freeplay is crucial as mentioned before. [/QUOTE]
