    What the heck, so GM goes back to drum brakes on the 1500 Silverado's and Sierras? Why? Everybody knows that drum brakes can't dissipate heat like a disc. I think even the WT trucks have crossover braking which isn't even 4 wheel ABS. Why did they go back to drums, anybody know?

    I think they were having some reliability issues in the Rust Belt with the rear disc setup they were using, something about all the salt screwing 'em up.

    it was cost vs performance

    rear brakes don't do as much braking as the fronts and the disk set up cost allot more then drums to maintian but don't offer enough performance to justify.

    I'll take drums back any day!

    I'm on my second set of rotors and I have less than 20K miles! (truck in sig)

    The steel they use is crap. The calipers rust and no longer slide, leading to uneven pad wear.

    My latest set was put on in March, and they already look like hell.

    I don't live by road salt so I don't have those problems.

    Drum brakes don't have as much brake fade as disc brakes. Also, how many road tractors you see with rear disc? They use drum for a reason.

    cause its not like you dont see a bunch of those things jack knifed every year. air brakes work on a spring the air keeps them open when you shut the air off the springs clamp them together. drums r cheaper i guess here i had 30k on my truck and had to cut slots and break the back disc off rust is nasty

    thats because you have a chev.my f150 has over 200000 miles and the rear have only been replaced once.they stop the truck when it rains,not like drums.they get wet and wont stop your truck as well.

    Thanks k911lowe for bringing us back to topic. I'm also considering a new f150 as well, they are great trucks.
