What happens if air is let into the brake while changing oil.and how do I fix it
you must bleed them. there are several ways - 2 easy / less equipment ways are 1. if you have two people - open the bleeder on the caliper -then press and hold the brake lever in - tighen the bleeder then release brake lever -then repeat 2. open the bleader and let gravity bleed it both are a little messy, so have something to catch
put a rubber hose or piece of tubing from the bleeder into a jar of brake fluid, crack the bleeder loose, and pump the brake lever until there are no bubbles while keeping the reservoir full, then tighten the bleeder and see if your brakes are firm
If you let air in while you are changing the oil you can ride the bike for 2.5 miles then the automatic self destruct component will disengage you will hear a siren that is about 100 decibels steer the bike to a desolated area and run for cover. Currently AlQueda is using this technique in Iraq.
