Product Information
Full details
The PRO Brake Piston Lever is an essential maintenance tool for home mechanics and cycling enthusiasts who need to safely service their hydraulic disc brake systems. It provides a precise, leverage-based method to separate or realign disc brake pads without risking damage to the pad surface or the calliper piston, though it is specifically designed for pad spacing and should not be used to force open seized pistons beyond their original range.

FAQs
Will this work on both road and mountain bike disc brakes?
Yes, the PRO Brake Piston Lever is designed to be compatible with all disc brake systems, regardless of the bicycle type.
Can I use this to push back seized pistons?
The tool is intended for routine pad separation. If a piston is severely seized, it may require professional servicing or specific piston cleaning procedures to avoid damaging the seals.
Do I need to remove the wheel to use this?
Yes, you must remove the wheel from the bicycle to access the calliper and successfully use the lever to separate the pads.
Is the handle material oil-resistant?
The dual compound grip is designed for bicycle maintenance environments, but it is best practice to clean any hydraulic fluid spills immediately to ensure the longevity of the handle material.
Does this tool come with a warranty?
The product is backed by PRO's standard quality manufacturing guarantee. Check with your retailer for specific regional warranty terms.
Troubleshooting
The lever feels difficult to insert between the pads.
Ensure that the brake pads are not fully extended against a rotor or a pad spacer. If you are struggling, check if there is an obstruction or if the piston has been forced out too far.
Pistons do not remain retracted.
In some systems, hydraulic pressure causes pistons to slowly reset. Use the tool to hold the pistons in place while performing maintenance or insert a proper bleed block after retraction.

Setup, Compatibility & Care
This tool requires no formal setup—it is ready for use immediately out of the packaging. It is compatible with all hydraulic disc brake setups, including road, mountain, and gravel specific systems. To care for your tool, simply wipe the head clean of any brake fluid or road grime after each use. Store in a dry, temperate environment to prevent the dual compound grip from degrading over time. Ensure the tip remains free of debris to prevent cross-contamination of your brake pads during the insertion process.
