Item # PAR000D

Using the nearly-obsolete cone wrench for spreading peanut butter is a noble application of the bike-shop icon. Using it to spread brake pistons, however, is an indication of beater status. Unlike the purpose-designed Park Tool Brake Piston Press, its edges are pad-damaging sharp and you're bound to bend the handle.

Not to mention, peanut-oil residue on pads or brake dust in your lunch isn't going to lead to good things down the road. The Brake Piston Press is designed specifically to slide in-between pads without compromising integrity so reinstalling wheels and calipers is a struggle-free affair. It's constructed from steel, with a rubber handle that's offset for easy, ergonomic use.

Better than a screwdriver.

  • Familiarity: I've put it through the wringer

Made wide enough for 4 piston brake calipers. Tough enough to pry back stuck pistons. Great for changing pads or resetting and centering your calipers. Nice shape that doesn't mess up your brake pads.

Get the right tool for the job

  • Familiarity: I've put it through the wringer

When changing brake pads or servicing brakes, make sure you have the correct tool. Quit messing around with trying to push your pistons back in with screw drivers or wrenches. This does the job in the correct manner.

the tool for that one job

    I like it cause it pushes the pads to the side. Would prefer it to be just a hair thinner. I mean.. you can always bend it to push more but some brakes it wont fit into which stinks. Its way better than using a flat blade because it wont mess up your brake pads. The angle of the tool is nice and the grip is solid.

    the tool for that one job

    The right tool for the job...

    • Familiarity: I've used it several times

    Works as designed and impossible to gouge your pads as you might wedging a common screwdriver in there...

    Avoid Damaging Your Pistons

      Sets pad spacing great with care, helping avoid doing potential damage to your pistons if done by other means. A great tool to have in the kit!


      • Familiarity: I've used it once or twice and have initial impressions

      Perfect little tool for setting pad spacing. Also won't cause damage to the pads when you're resetting them after accidentally pulling the brake lever when a wheel is off during maintenance. If you have hydraulic disc brakes, you need this in your tool collection.

      Needed tool in the box

        The wedge is a needed tool for modern hydraulic brakes! Spaces the pads and Pistons perfectly and evenly.

        Right tool for the job I never wanted

        • Familiarity: I've used it once or twice and have initial impressions

        Don't you love it when your buddy, coworker, or enemy grabs a handful of brake when your wheel is off your bike? Instead of using a screwdriver and possibly scratching your pads or setting the pistons back in incorrectly, use this tool to get those speed scrubbers back in action fast. Keep this tool in your toolbox or trunk just in case.

        Handy Tool

        • Familiarity: I've put it through the wringer

        This tool is mighty handy while servicing your disc brake calipers. In the past I would use a flat head screwdriver to push the pistons back in which didn't work that well and more likely to cause damage to the brake . The large flat surface of this tool makes service easy and the handle is also comfy.
