Question to Avan pop top owners

Cars of that era overseas suffered a lot from this "illness", non-ABS brakes lead many times to overheating and as a consequence the "soft" material of the brakes suffered, leading to hardening of the bands-pads, starting to not brake well, making friction sounds and scratching the drums-disks. Had a Jeep Wagoneer and a Chevy Malibu with that. That is what mechanics called Crystallization, rearrangement of the crystal structure of the pads leading to hardening, a common process in Physical Metallurgy.
Of course a camper does not brake a lot but being electrical-mechanical brakes they apply a constant pressure, different to hydraulic brakes and since I am the 3rd or 4th owner of the Avan I can not know its early history.
Thanks anyway for the advise.

Forget all that high tech crap. Avan brakes are just simple old style brakes. I have only seen drum brakes on them, was yours a special build?

Only reason you would change backing plate is it's usually not much dearer than replacing the shoes.

Magnets maybe, but on a little Avan, I'd be very surprised if the drums needed replacing.

Thanks to all, I'll bring it to service next week.
