Revolver Posted January 24, 2008 Report Share Posted January 24, 2008 HelloIf more air gets into the brake, how long should I leave it before it'll get to the top? And do I need to pump the lever at all? Quote Link to comment Share on other sites More sharing options...
psycholist Posted January 24, 2008 Report Share Posted January 24, 2008 (edited) If it's a closed system like a Magura rim brake then you'll have to bleed it to get the brake working properly - it doesn't matter where the air is as all the fluid in the brake must be pressurised for the brake to work. If it's an open system like current Hopes (And pretty much every other hydraulic disk except the old C2's from Hope and Giant's own brand disks), then pumping the lever (Provided the lever is the highest point in the brake) can move air bubbles from the caliper/brake line to the reservoir where, if the bubble is small, they won't affect braking. If you pull the lever and let go of it suddenly that seems to help move the air quicker. Handy if you've shortened the brake line, swapped brake lever around or are topping up the reservoir after it has lost fluid through a loose fitting or brake pad wear has drained the reservoir.If you are shortening the brake line take the wheel out and pump the brake pads out before opening the brake up. Then after cutting the brake line down you can reassemble the brake and lever the pads apart to push any air bubble formed in the brake line back into the reservoir.
