Hi on 997's with PCCB there are yellow Zircon inserts on the Pistons that sits between the pistons and the pads. While changing these fell out and they are really hard to get to sit back in the rubber dust caps/grommet and seal completely. Anyone have any tips on how to get these back in place and stay long enough to get the pads back ?

Or can i just put them in place and don't care that the the rubber does not seal completely or will that cause damage to the pistons ?
