These are great, you don't have to use a tire lever and try to get all of the pistons to retract which can be difficult when one moves in and another moves out. Definitely helpful when changing brake pads. Never knew I needed these until now!

I ordered these spreader tools simply to add to my ever growing bike tool collection. While I know that inevitably I will need to spread the pistons, either due to an ordinary pad change, or because I did something silly like pulling a brake lever accidently while working on a bike with the wheel removed. Yeah, yeah, yeah, I know... I have the spacers to prevent such things, but I don't always take the time to find and install them while working on things, so... So, anyway, I ordered these to have on hand for when I need them, rather than needing them and then having to wait to get them, or doing something else silly, like using an inappropriate tool and gouging up either my pads, or my pistons. Checking these out tells me that these will work well. I like the sliding block concept better than the "prying" type of tool as they allow a controlled and even pressure to be applied to both pistons at the same time. I feel this method is less likely to damage something inadvertently. The material is also MUCH less likely to mar something than the usual steel spreaders. I think these will be simple to use and I almost look forward to using them enough to give them a try without even having a real need to use them... I said, "ALMOST"! Haha But yeah, for the price, and considering the design, I think this is something worth adding to the bike tool kit.

You can get the job done without these. But, if you service your own bike you, may as well have the proper tools. Working on hydraulic disc brakes can be a pain so get the tools. These work beautifully, are strong, and reasonably priced.

I have used tire levers to push the pistons back when changing disc brake pads. Sometimes you should just get the right tools. These clever slotted tools push the pistons back safely applying symmetrical force. The groove keeps the tools aligned. Perfect for the task. Recommended.

I wasn't quite sure what to expect with this tool, but took a chance on it being okay. It's actually a very clever design that works very well, and I'm glad to have it in my toolkit.If you work on bikes, sooner or later, you're going to need to push the caliper cylinders back into the housing... whether because you accidentally pulled a brake lever while a wheel was off, or during brake servicing due to pad wear. Rather than risking damage by using a screwdriver or other tool, these plastic wedges provide an easy way to push the calipers back.Note there are no instructions with the tools, but the basic technique is to look for the small 'bump' on the end of one tool and match it up with the shallow 'groove' in the other tool (so they face each other) while inserting each from the opposite side of the caliper. This tongue and groove design keeps the tools from sliding sideways while pressing the cylinder(s) back into position, and the wedge shape of each tool provides a method of starting at a very narrow gap yet keeping the pressure on the caliper cylinders square and even.This is a great tool, in my opinion, and well worth the price.

What a simple yet handy little tool! I have to maintain me and my wife's bikes so brake pad changes and bleeding is a regular occurrence. Usually, I'd use a plastic putty knife type of tool to push the pistons back but always had to fight each side. One side gets pushed in, the other gets pushed out a little, and you do this back and forth dance for a few tries before they're far enough back to be out of the way. No more! The incredibly simple parallel design of this tool allows you to handle two opposing pistons at once, so you just squeeze the tools together with the finger loops and both pistons retract with equal pressure. I've got Magura MT7's on my bike and I don't think I could fit two pairs of this tool to retract all 4 pistons at once, so I do have to hit both sets separately, but it's still lightyears quicker and more fool proof than my previous method. My wife has Sram motive brakes and being 2 piston, it's so stinking simple. One thing I'd like to note - if you watch a certain high profile mtb youtuber, he tested this set not long ago and didn't realize they're supposed to be use in conjunction with each other to apply equal, and parallel pressure to push the pistons back in. He only used one "wedge" which is the incorrect way to do it, it will still apply an uneven pressure that way just like putting a flathead screwdriver on the edge of a piston. Don't do it that way, when used properly, this set does the job right and will never damage your pistons or seals! Big win for simple, yet easy to use engineering!

Works well to separate hydraulic disc brake pistons. There is a slotted groove on top of one of the spreaders and a nub on the underside of the other spreader, and these fit together to ensure that the two spreaders stay aligned when you push them together. These spreaders only push the pistons as far apart as the edges of the space between the two sides of the caliper body, so if you need to push the pistons farther back than that (assuming they can be pushed farther back than that), you'll need to use another method. I've always just used a narrow plastic tire iron, and that works just as well, but with the tire iron I need to push in one piston at a time.
