opppps Mate!! "never"use a tissue. if the tiny piece of tissue fall in that master cylinder,it can cause you nightmares. just go to a "dollar" store and have some few plastic syringes and suck it out and dispose the old plastic syringe...not worth the nightmare it can cause. saw this happen before and cause lots of Dollars and issues with brakes being stuck because of this ordeal. I personally will only use syringe or Turkey Basker and the dispose after use. ty sir Cheers great video
