Pulled the PS rear wheel off my F150 to figure out what was squealing. Pulled the caliper, looked OK. Tried to pull the rotor...stuck. Banged it off, saw a ****-ton of rust on the parking brake actuator, cursed. Pulled it apart, unsiezed the actuator, knocked some rust off the contact points, applied brake grease, started to put things back together.
Then I got to the *******-like shoe retaining clips. Cursed a bit, got it back together, sighed. Figured I'd check the other side, found more rusted up parts. Cursed again, pulled it apart, unsiezed the actuator. Cursed a bunch more at the retaining clips, torqued the wheels back on road tested it, then cracked open a beer.
Ford came up with a REALLY lousy design for this one.
