Hi, I'm in the process of changing the handbrake shoes on my '96 850. While doing this two (one either side) of the small clips which hold the shoes in towards the backplate snapped (rusted through). These are riveted to the backplate and, I'm informed by Volvo, they are not a separate part. Has anybody any info/tips? I don't feel inclined to fork out for two new back plates if it can be avoided. Handbrake is working fine but the shoes are of course rubbing slightly on the inside of the drum.
