Question about bleeding brakes???

[Suncoast]

Okay so I've got my six pots mounted and am about to fill the system with new Dot 4, and it occured to me that with the way the brake line goes from the right caliper over the fender to the left caliper I have a high spot in the line where air can be trapped. Should I just bleed them as they are mounted or should I dismount the left caliper and put say a paint stick between the pads and then lift the caliper up and then bleed it so that any air in the line can escape? Anyone else thought of this?? Maybe I'm just being overly concerned? what do you guys think??

Does anyone have any input??

The high-spot shouldn't matter if you do it correctly but I would eliminate that to save any possible problems.

Here's a recent thread on brake bleeding which you may find useful:

Just bleed them as normal.You shouldn't have any problems. The air WILL come out.

it would only be an issue if you were to have a larger area for air to collect in at that high point. The fluid going through the line will push the air through. Since it will be a bleed though dry lines and calipers you may want to let it sit overnight and then rebleed once the fine bubbles settle out.

I have clear tubing that i use to bleed the lines. What you can see happening is as you pump, the bubbles progress down the line. then you close the screw, let up brake to get ready for the new pump, the bubbles start to float back up the line. Its a two step forward, one step back kind of thing. So just make sure you're pumping fast enough, and it will be no trouble. Don't dawdle between pumps or the bubbles float back up to the top of the bend.

Suncoast - I use a hand vac pump that maintains constant draw on the system. Using this I have never had a problem with bikes or cages with entrapped air in the system.

Decided to install Speedbleeders the other day. Didn't worry too much about getting air in the line. Took the old bleeder off, lost some brake fluid, but got the new Speedbleeder on pretty quick. If any air had got in the Speedbleeder would have allowed me to quickly pump that back out. I just left the calipers in their normal position (with a rag to protect any paintwork). No problems. The brakes are rock solid now - much better than before - so couldn't have got any air in the lines.

Not sure if this helps, but someone on this forum suggested cable tying the front brake leaver back overnight to squeeze out any air in the lines. I did this. Not sure if it actually did anything - but the brakes are more solid that they have ever been.

I'm now of the view that the standard four pots are fine if you keep them clean along with the fluid.
