On/Off switch difficult to move, wrench failed, put in new battery, still doesn't work. HF doesn't catalog this item anymore.

I have two of these. They work well and are cheap ($7.99). Just put this in the caliper, use an old brake pad to evenly spread the force and compress the piston. Sometimes, if the piston is a tight, you have to use pliers to gain leverage, but go slow and this tool works fine.

I have two of them for double piston calipers. Put in the old pad, then put these next to each other, and slightly compress one, then the other. Repeat as needed to full compress the piston.

Got it open box for $20. I use it for automotive testing and it works quite well. Pulls a vacuum and will measure one, just like it should. I haven't used it to bleed brakes, but I am sure it would work fine. Tip: pick up vacuum pump adapters at Autozone to add to the ones that come with this kit. You will ALWAYS need the adapter you don't have so get as many as you can.

I have three and use them often, they all still work and the tips are not rounded.

I love all their power cords I have 3 of these and they all work fine after a year of continuous use.
They have lower cost ones at the warehouse clubs and I get them there now.
