I drive all year.
And than you get WINTER , with roadsalt and other stuff.
Just like the 2 years before, my brakepads got stuck in the calliper.
Now I made a simple and cheep modification on the rear brake.

Remove the screw with a flat screwdriver and remove the rusty pin

I found this on Ebay

Refit everything, with a little grease, and you're good to go.
