Last night I cleaned and lubed my XT disc brake caliper pistons, everything went great until I put the wheel back on and went to test the brakes. I realized that by having the bike upside down and pumping the brake lever to force the pistons out, I may have gotton some air in the caliper. It took 2 minutes of pumping before the brake lever was firm again, I checked it this morning and it seemed fine, should I have the brakes bled or is this normal ?

I would definatly bleed them if I was you.... there is air in your lines.

you can't be careful enough when it comes to braking..

My mechanic at my LBS said it was normal to have to pump up the brakes, I also found the same information on the Shimano web site under resetting brake pads. He seems to think its fine so I won't worry about it. Thanks for your help...
