Review on 🔧 A-Team Performance Brake Proportioning Valve Bleeder Tool: GM Style Combination Valves Compatible with DISC/DISC and DISC/DRUM PV2 & PV4 AC Delco 172-1353, 172-1371, Black by Brett Robinson

Works great, I lost the tool that came with my kit. Ordered, it came quickly and the needle didn't break like people that others have problems with. It's plastic although I thought it was metal, but the stitching is solid no matter what. I recommend using gravity pumping before pump breaks to pump fully. I'm not sure if this is necessary, but it reduces the stress on the stylus.
