Review on 🔴 YSTOOL Brake and Clutch Fluid Hand Pump Vacuum Bleeder Tool Kit - Efficient Brake Oil Change and Power Steering Fluid Bleeding Set for Auto Car Truck Motorcycle Use (Red) by Todd Stone

the case it came in was very nice and it looked like a well built pump. But as you can see from the picture the o-rings were too big and so it was very difficult to maintain a proper seal. Make a good seal, but still not enough to suck oil through the exhaust valves. I've also tried using it to pump oil out of the master cylinder oil reservoir, but that didn't work. This is my experience, it may be different for others.
