Hydraulics-laying bike flat?
Last summer I put new XT hydraulic discs on my bike. Can I lay the bike (on the left, natch) in my pick up bed with the bars turned 90 degrees to the right and not get air in the lines? I have a hard tonneau on the truck, so the bike will be very near flat, with the front wheel removed. I drive miles of twisty roads, so there will be lots of sloshing around and lateral Gs pulling on things. I was thinking maybe I could prop up the top tube and stem with a large piece of foam. What say ye?

That doesnt matter what so ever. They are air/liquid tight. What you SHOULD worry about is accidentally pulling the brakes levers while there is no rotor in the caliper (when you have your wheels taken off). Then you have to push the pads back in and sometimes bleed the lines, etc. Its a pain in the butt.
But no, you dont have to worry at all.

what is a natch?
lateral g's? have you tested your vehicle on a skid pad? what can you pull? or do you just drive like a maniac?

natch: slang for "naturally" The truck is a 2000 Ford Ranger (a joint Ford/Mazda vehicle) and I am usually not too fond of Detroit iron, but it does sort of handle with the big tires and stiff springs, probably lucky to get over .8 on the skidpad, though, just a guess. I damn near rolled the thing playing one day, so no, I no longer drive like a maniac.

I have hydraulic discs on my Kona and my Jamis, I lay those down all the time. Think about it, if you couldn't lay you rig down flat, what would happen if you took a spill on it?........

I just thought that the cornering forces of normal mountain road driving might have the effect of momentarily going a little upside down to the hydraulic system when the bike is lying flat. I'm not trying to come off like a formula 1 driver. Thanks to all who replied.

It will be fine lying flat - so long as all your fittings are tight & you have no leaks....

I am touchy, but I am also glad to provide amusement to all who find this funny. I was told, years ago when almost everything was Hayes, that hydraulic brakes will get air in the lines when stored upside down. Is this true? Was this true for only early Hayes products? Is the little rubber accordian/gasket on the XTs 100% effective at keeping air out of the rest of the resivior, and thus out of the lines when stored for weeks or longer upside down? Have I been living a lie??

OKAY- my bad. I aasumed it was true that the calipers should never ever go above the resivior. Hey, I heard it in a bike shop, so it HAD to be true!! WAY off topic: If you like Pirate humor check out Zap comix number zero or 1, I forget which.

If the fluid in your brakes isn't topped off you WILL get air in the lines by turning the bike upside down. Shaking the bike and squeezing the brakes a bunch of times (when its rubber side down) gets the air bubbles out.
