Brake Proportioning Valve Bleeder Tool, Valve Bleeding Tool Compatible with GM Combination Valves, PV2 PV4, Disc/Disc Disc/Drum 172-1353 172-1371 (Blue)

Held proportioning valve in center position allowing me to fully bleed both front and rear brakes on a new build

Worked great and well built!

perfect. so perfect I never took it out 🤣🤣

This is a simple tool so it's hard to screw it up. There are cheaper ones that are plastic but I like these.

For me I don’t know if it works are not I couldn’t tell any difference. Concept sounds good though.

Cool thanks

This will come in handy for brake fluid bleeding
