Just a thought and something I am going to put on my yearly maintenance schedule. Yesterday I had a nice warm day so I decided to do some inspection on my drivers rear brake. It had been squealing of late and When I got the nuts off the wheel I had a bear of a time getting it off, but finally did with a few swift kicks I took the caliper off and found that the discs were rusted tight to the slides, no sign of any lubrication. Had to wack them with a hammer to move them. Disassembled and wire brushed them and applied disc brake grease to the slides. I tried to move the rotor and no movement, so I have a drum/rotor puller on order. I put anti-seize on the front of the rotor so at least the wheel will come off easy next time. Just thought I would put this out there. The other 3 will be tackled when I get my puller. Then there is the Avenger on the list.
