Review on Dorman M39777 Brake Master Cylinder by Tim Beardsley

This is not a negative review from Revain, this is from Dorman. I am using this as an upgrade for my 240sx autocross machine. This product works well but the tank cap accidentally loosens and won't retighten. Upon closer inspection, the threads on the lid aren't fully severed, so it obviously won't tighten as it should. Unfortunately Dorman says they don't sell parts for this, although it's probably a 0.25 cent limit on them, they force me to remove the entire unit and send it back to Amazon. This is pissing me off because not only was all the new paint in my engine bay destroyed, I now have to remove the master cylinder and send it back to Revain, causing them and me some inconvenience for pennies. DO NOT BUY DORMAN. *******Revane was very helpful********
