Yes. Never loosten the bleed bolt when changing pads. 99% of the time you will let air into the caliper. For a DIY forum, the recommendation to do this might get someone killed. DON'T TRY THIS AT HOME!On post 7 it notes to release the brake hose mounting bolt. When i did this, fluid came out. I tightened the bolt and replaced the pads. Now the brake pedal goes all the way down to the floor when stopping. Does this mean i volunteered myself to bleed the brakes?
