Bleeding brakes?

I am trying to bleed the brakes in my 1990 Lumina (3.1 v6), what size wrench is the bledder screw, all my tool sets i have a 3/8 and a 7/16 and 3/8 is to small and 7/16 is to big! is there a 13/32 wrench because none of my tool sets come with one


metric is better

metric car man!!!
And you bleed one wheel at a time if it has ABS.!
none abs Rr,Rl and then Rf,and then Fr.
Do not forget to adjust the rear brakes after this.


4 clicks on the emergancy and that is it, if you get them to tight the pads linings will drag.

Your bleeder screw is 10mm... also if your car is abs, after you bleed the wheels, you need to bleed the abs module (front screw first, then the rear screw). Bleed them with your car running (trust me on this...). the bleed screws on the abs module is 8mm.
