I may have air in my rear brake lines. Other than bleeding them is there a way to get it out? I thought I remember something about holding the brake pedal down overnight?
Thanks,

I did change it but think it may have gotten some air in it. I checked the pads and they were almost new looking but the brake pedal feels like before the fluid change, kind of soft and it seems to go down more than it should.

I use a mighty vac (hand vac) to draw fluid through the system. It seems to work pretty well..

zeus661.....sometimes you might have to bleed the system several times to get all the air out...i too use a mighty vac to bleed, and or change the fluid. go back and bleed it again... you might be suprised that this extra couple of bleedings will take care of your problem |

Sometimes an air bubble can get trapped in the caliper, and slow bleeding may not push it out. Try connecting a snug fitting hose to the bleeder, with the other end in a jar of brake fluid. Open the bleeder enough to allow fluid to flow, and give the handle or pedal a quick “jab”. Hold it down, and close the bleeder. This will usually dislodge a stubborn bubble. Also if the reservoir went dry during bleeding, you may have to bench bleed the master cylinder.

I've seen the front brake lever tied down many times. Never noticed a brake pedal but why not give it a try. I've used the Mity Vac for many years works good.

If you care enough to change the brake fluid, then you should have a lot left after doing your system, and it should be thrown away by the time you do your next replacement, as you need to start from a freshly opened container.
If you're like me, and I haven't replaced brake fluid for any vehicle I owned in over 30 years, then doing a proper bleed is still the way to go. You where hoping that just holding the pressure in the line would allow the air to come out slowing may work, but this would take multiple times, over multiple days, wouldn't it just be easier to do a proper bleed in conjunction with a vac pump?

If you change out the fluid in the front and rear brakes plus the clutch, you will use almost an entire bottle of brake fluid. That way, you won't have to throw much away.

Uhm. . . . I figured the two year old stuff in the capped bottle in my garage was better than the two year old fluid in my bike. It was certainly a lot cleaner. In case it was not clear, I did NOT start from a freshly opened container on my last fluid change. To each his own. Hey Zeus661, how many miles on the bike and how many (if you know) on the pads? If you pump the pedal, does it get firmer? |
