05 Silverado parking brake performance.
Posted: Sat Aug 08, 2020 12:51 pm
Installed a complete 2005 Suburban disc system on an older GMT400 4x4- the actual brake performance with hydroboost is good but part of the reason to change was to get away from an older poor performing driveline brake back into a oem parking brake. My work truck is a 2018 Silverado 1500 and the parking brake holds fine. On the GMT400 everything is new so I'm assuming two things- the inner shoes need to mate better to the drum (also new) and a final/ongoing adjustments done, or the GMT400 original footbrake does not have the same leverage as the newer style trucks. I guess what I want to know is...was the GM system adequate assuming a proper maintenance program (I am assuming people didn't service their rear brakes every couple of years) I know they went bake to drums for a bit them back to disks- did any major components change between 2005-2018?
