Undercarriage Retraction.
As a humble wannabe I was leafing through a good friends B757 tech notes the other day and I came across the section on undercarriage retraction. It said that there was a braking pressure exerted on the wheels during the retraction (obviously to slow them down from the V1 speed before they sat in the fuselage)
It made me wonder though - would it theoretically be possible for the brakes to "jam" on during retraction and remain jammed until the undercarriage is lowered during the approach? Methinks that this could cause a little bit of the brown trouser type scenario up front!!!!
So could anyone shed some light on what would happen, is it possible, any ideas to sort it etc etc etc - been bugging me for days!!!
Thanx in advace

PS Do all aircraft have this braking thing going on during retraction or is it unique to the 757???
