Brake Tool for Sram, Bike Ultimate Piston Press Tool for Sram Caliper, Hydraulic Bike Disc Brake Caliper Piston Press Tool for Sram, Width 1.1 inch, for Sram 2/4 Pistons, Not for Shimano

This tool is a must have if you service bicycle brakes. Beats the heck out of a screw driver prying the pistons apart, or a pliers scratching the caliper.

This is almost as good as the original Sram tool. Unlike other copies, this one has a limit stop, so you cannot over-expand it; the major difference vs. the original is that threads appear to be cut a bit rougher, so the tool has a bit more "slop" in it, and the adjustment knob doesn't turn as smoothly. This doesn't affect the functionality once the tool compresses the pistons, so its not a big deal. Just something to know.It's worth getting this one, especially since the SRAM one might as well have been made from unobatanium.

Worked for my needs to push my sram rival pistons enough to put new brake pads in without rubbing. Also I didn’t need the Allen key as the thumb screw give enough leverage to push the pistons. Great product.

Looks and works just like the sram one.

I've tried a bunch of different things for pushing pistons in, but always fallen back to the old standby of using a small wrench. However, this one works exactly as I hoped it would. I ordinarily would have paid for the SRAM tool, but its really hard to justify the price they are asking. This tool feels burly, and it is super smooth when you are expanding the wedge to press the pistons in. I'm very pleased and definitely recommend to anyone in the market.

Works fine, but definitely has a little more play than the SRAM tool. Also, the Allen wrench shown in the pictures was NOT included. Not a big deal, but don't show it if you're not going to include it.

I’ve only used this a couple times and it seems to work great. The quality is quite good and the price was great. I think this is a decent tool to skimp on versus purchasing the sram tool this is a copy of.

If you have bled your own hydraulic brakes on a bicycle, sometimes getting the spacer wedge in can be tough if you have too much fluid in the system. Simply slide this in and use the screw to expand the metal and push back the calipers. Simple, effective. SRAM OEM is just too expensive for no benefit. Great tool.
