Texas vehicle safety inspections Have sidelined at least one truck of mine. My GMC has the rear disk brakes, with a separate little drum inside just like our Tracs do. GM didn't design them very well, though, and the parking brakes don't work on a large percentage of them. If you don't use them, they will actually wear themselves totally away! And who needs to use a parking brake here in souutheast Texas where there aren't any hills? I had to replace the rear disks, pads, and parking shoes before I could get it inspected.
When I asked the technician why he wouldn't pass it because the "parking brake" wouldn't work, he said the "emergency brake" had to work. When I told him GM didn't equip these trucks with "emergency brakes", he told me he couldn't pass it without one. It didn't even have to stop the truck to pass, only hold it (ok, that is a parking brake). Per GM, they are only designed as parking brakes, not emergency brakes.
Oh, and Harris County, Texas also has an emissions test, as well.
The counties surrounding Knoxville, Tennessee do not have vehicle inspections, but cops can write you up for safety violations if they feel like it.
