Does the Sierra has as well 253mm vented disc brakes (i.e. in 4x4 version)?
Some Sierras may have sued small 253mm solid discs, 4 stud.
Pretty sure that any vented discs on a Sierra were 273mm. ie 4x4 cosworth. ( 2wd cosworth solid 273mm )
Not sure what a basic say 2.0i 4x4 non cosworth sierra used.
edit..
page 89 gives some listings. 253mm discs, 260mm discs. 4x4 even on lowly models vented.
