beduan Disc Brake Piston Caliper, Wind Back Car Repair Brake Pad Replacement Tool for Automotive

Be aware of what this tool really looks like; see two photos. I wasted more than an hour trying to make it work without having to modify the tool. I had to "shave" the four prongs-two on each side, to make this tool work with my 2016 Mazda 6 rear break pistons. The photo on the sellers portal shows the tool without prongs. I had to replace my brakes right away and did not have the time to return it to get my money back. I do not appreciate deceiving photos. Sell what you say you are selling, please. Other than that, if this tool would work with your brake pistons, then it is a well constructed tool and a good value for the money. They get five stars for that, but one overall rating and easy to use.

When I saw the package said left-handed, I was upset. So, I went back to the item's Amazon page and the description said right-handed...then I was really upset since it wasn't something I overlooked. However, it turned out the package labeling was wrong and it really was right-handed threads. The moral of the story is to not automatically believe the package labeling without verifying it.Anyway, I bought this to use on an 03 VW Jetta. I had to grind down the nubs on the round plate piece in order to get it to fit in the rear caliper. I ground down about 2/3 on the ones that are the farthest apart (the ones that fit the caliper piston), Then I ground down the ones that were closer together ~3/4 of the way. In other words, you grind down the ones that fit against the caliper piston enough so the plate sits flush, then you grind the other ones down most of the way in order for the whole shebang to be able to fit into the caliper.

This didn't work for me. The distance between the hole and the edge of the plate was a bit too large for my 2013 Mazda 3 caliper; the screw wasn't square to the piston so the end of the tool wouldn't stay seated in the holes in the piston. I could probably grind the plate down a bit, but in the end I just used a 3/8 ratchet and a bar clamp. Good idea though, so I threw it in my toolbox rather than returning.

Compared to the previous tool that I owned for threading in the brake caliper piston, this fool worked great! my previous tool was a universal type of tool that had movable pins that no matter how much you tightened the allen wrench type screws down the jaws would not stay in the position you wanted the pins to be in to thread in the piston. This new tool had preset pins and was reversable to accommodate different diameter pistons. A great tool!

The package said left hand threads and the description said right hand threads. In reality, it didn't matter much, as it did the trick. I liked this enough that I'll use it again the next time I work on Honda Rear disc brakes.
