I was getting ready to replace the rear disk brakes on my 1998 Saturn SL2. You need to turn the piston in the caliper to get it to go back in. I heard you can use a pair of needle nose pliers, but this tool is so cheap, I decided to try it. It made the job much faster and easier. I really appreciated having this item.

Worked great on the rear calipers for my 2006 Civic Si. Unfortunately the teeth don't seem to have long-term longevity as the started to round off a tiny bit each time I used the tool. Of course, you don't do rear brakes every day so I feel that this is worth the cost as an occasional use tool.

Just completed a rear brake job on a 2008 Honda Accord Coupe. This tool is a MUST, made the job of resetting the caliper so easy. Fits right on 3/8" drive ratchet. Offers 6 different "faces" to fit 6 different styles of brake setup. When I was done, simply store this in case with my socket set. I am sure I will find other ways to use this. Perfect DYI tool. Bottom line is the $10 price saved me from paying a shop $350+.

this is a tool to turn the rear caliper piston to retract it on cars that have cable parking brake with rear disks... notably a lot of Ford / Lincolns / Jaguar.

its a well made tool that has 6 different notch patterns to fit evey piston type I've ever run into... very very handy time saver

enjoy

This tool gets a bad rap from Audi & VW owners, they say it won't work. They are wrong. In order to get this tool to work on the rear brake pistons of Audi & VW's please follow this simple how-to guide: One side of the cube has 4 prongs. Grind or file or cut off 2 diagonally opposite aka kitty-corner prongs to allow the cube to fit the vw rear brake piston.
Use with a 3/8" ratchet. It can be easier to fasten the rear caliper back onto the carrier without the rotor in place while using this tool. That way you get a little extra leverage.
Use as follows: engage the two prongs and turn the piston 180° clockwise. Remove the tool. Use a generic caliper tool or a c-clamp and push the piston in about 2mm. Keep alternating back and forth between the cube tool and the c-clamp until the piston is almost all the way in. If you are strong enough, you may not even need the c-clamp - just push with the cube tool as you turn. Instead of the cube, you can even use needle-nose pliers, but then you definitely need the c-clamp.

None of the sizes fit for my base 2001 Ford Mustang; all were too close together to fit into the piston notches.

So there I was, with the car jacked up, unable to fit the caliper back onto the rotor. Some people claim they can do the job with nothing but a pair of needle-nose pliers, but I couldn't. I had to painstakingly alternate between turing the piston with a pair of heavy-duty pliers and pressing down with a C-clamp. This piston tool was supposed to prevent this kind of aggravation.

I got this to replace the rear pads and rotors on my 2003 Jaguar S-Type, and it did the job alright. The little nubs were starting to round off by the time I was finished with the second side, but for seven bucks its cheap enough to be a disposable tool. However, the other 4 sides might be handy for other vehicles, so I'm not about to throw it away! As a side note: to compress the rear cylinders on a Jag like mine, both sides of the car turn Clockwise. This is not one of those cars where you twist in reverse for the other side.

Served it's purpose, was able to get the piston back into place using, not fool proof though. A third hand would have been helpful to keep the tool in place, it acted like a one tool fit's many uses because it is. Would buy again if this one gets lost.
