Anybody else have much trouble getting their brake fluid flushed and bled? A few weeks back I flushed mine, front and rear. The rear has been fine but the front has given me some issues until a few days ago. I have never had issues before.
Mine is non-ABS so no modulator or anything. I use the old school method of squeezing the lever, open bleed valve, close valve, release lever, and repeat. It seemed to be fine until the bike sat unused for about 3 days, then the lever got spongy and would almost come back to the handlebar. If I exercised it several times it would then pump up hard and be good for another 3 days or so. So after the pull got soft I rebled the fronts. I probably bled them 3-4 times after finding the lever soft 3 days later again. I considered a remote possibility may be a leak at the bleed valve so I inspected the bleeder seating surface but it looked OK.
Originally I had used a different (newer, sealed) container of fluid (all DOT 4) on the front brakes so I wondered if I got a bad bottle of fluid that had air entrained in it or something. Seemed remote but I bought a new bottle of fluid, flushed, bled the front brakes and waited to see results.
That was 3 days ago and the brakes are still good with a hard lever. I know the odds are I got air in the system while flushing originally but It was pretty strange that it would be OK then get soft and repeat itself. I haven’t ever had this happen before. Anyway I think it is good now but wondered if anyone else has had a hard time with them. It looks like most of you use speedbleeders or a pump instead of old school.
