A great tool for resetting the clearance on disc brake pads. You leave the pads installed and easily press on the pads to spread the pistons. I clean the PS-1 with isopropyl alcohol before every use to prevent accidental contamination. Fast and easy adjustments. I can't ask for anything more.

I like to spread my brake calipers before reinstalling my wheel and this does the trick. It's super easy and works a lot better than using a plastic tire lever.

I've started trying to do my own mountain bike maintenance. I typically get half way into a task and realize I need a special tool. Same story doing a brake pad replacement. Price on the Park Tools option was within my budget and next day delivery saved my weekend ride.

Metal is a little thin, but functional.

I bought the tool to separate the old pads so I can easily remove them. This tool will outlast me for sure.

The Park Tool PS-1 Disc Brake Pad Spreader probably doesn't do anything a flat screwdriver or putty knife wouldn't do just as well. But the first time I removed my tire I made the mistake of hitting the brake, locking up the disc caliper. Being the gross amateur I am, I darn near damaged the brake trying to get the wheel back on. That could have been an expensive mistake.The nice thing about this tool is that it is designed to resemble a section of brake disc. That means you can adjust the caliper with the tool in place instead of the wheel. So it does a lot more than just pry apart two misbehaving brake pads.Proper brake adjustment is vital if you are going to spend any quality time on a bike, and the local bike shop is an expensive option to visit with any frequency for brake adjustments. Learning to do it yourself with this tool is a great option.

I was using the widest flat screwdriver in my toolbox before to depress the pistons into their cylinders, and I can tell you it takes a lot of precision to depress a piston with a force applied to its exact centre, or otherwise the piston refuses to move. Park Tool is known for their bike service tools, and this piston spreader is so much easier to use. It's well worth is price, as spreading pistons is what you have to do every time when replacing thin and worn brake pads with the thick, new ones. You may even afford a luxury of carefully pushing the pistons out to clean their side surface, something I tried to avoid, as a simple screwdriver is a very unwieldy instrument for pushing the pistons back into cylinders. Get it, you'll love changing your brake pads with it! There are quite a few instruction videos on YouTube on the correct use of the tool, including some from Park Tools themselves.Note that the tool is specific to hydraulic brakes; you don't need it if your disk brakes are cable-operated, like, for example, a lower-grade Tiara disk brake and some other types. It's specifically designed for hydraulically operated brake pistons.
