Service Parking Brake

[Age525]

Just sharing some info here. Had a service parking brake message come up in me '20 2500. Truck has about 27k miles. Pulled codes C060B and C0616. Pulled the L/R wheel to inspect and both parking brake shoes had no lining left at all. Passenger side actually fell apart when I pulled the rotor. Replaced the shoes and cleared the codes and its all good. FYI you can replace the shoes without pulling off the hub but is is a little tricky, a pair of 45degree needle nose pliers definitely helps.

The codes are for the parking brake actuators. You sure the actuators or what sends a signal to the actuators isn't faulty?

 

And that's a lot of rust!

How does a parking brake shoe get worn to nothing on a vehicle with automatic release?  Are they set up to drag?  I can’t imagine going to the trouble of putting louvers over the radiator but them letting parking brake shoes drag.

Looks like the lining fell off when the metal part of the shoe started to rust.
