I want to change my brakes on my 1999 toyota corolla but im trying to figure out what size the lug nuts are. I have the original lug nut bar the car came with but im trying to use my torque wrench to tighten them back up. But i need to know the lug nut socket size. The most i had was 19mm. I was browsing the internet and the 2001 corolla uses 21mm ones. Can someone who actually knows confirm this? or just tell me what size.

thanks in advance
