{"product_id":"4-piston-brake-de-sticker","title":"Brake piston service\/de-sticking tool (for sticky pistons)","description":"\u003cp\u003eHaving issues with some of your brake pistons not moving properly? If so, you could be leaving significant brake performance on the table. Luckily, it’s a fairly simple thing to fix if you’ve got the right tool.\u003c\/p\u003e\n\u003cp\u003eHere's a tool that can be used on a variety of 2 and 4 piston brakes. The tool constrains all but 1 of the pistons so you can get the stuck piston moving with ease. Just drop the tool into your brake, pull the brake lever and hey presto, the stuck piston will move. Clean the piston with a cotton bud and \u003cstrong\u003egently\u003c\/strong\u003e press the piston back into the brake caliper with your tyre lever. If you want to clean them all, push them all back with your tyre lever and do them one at a time.\u003c\/p\u003e\n\u003cp\u003ePut simply, this tool makes it easy to advance a brake piston as far as possible without popping it completely out of the caliper. This allows for as much of the piston to be cleaned as possible, which helps you maximise your braking performance.\u003c\/p\u003e\n\u003cp\u003eThe tool looks a bit odd, but between rotating and flipping the tool you can extend any brake piston. It also has a chamfer on the leading edges which makes it easier to insert in your brake caliper.\u003c\/p\u003e\n\u003cp\u003eWe promise that the tool doesn't look nearly as bad as the product image, we just have been without photography resources recently and wanted to list it anyway.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCleaning procedure:\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eCarefully push all pistons back into the caliper using a tyre lever\u003c\/li\u003e\n\u003cli\u003eInsert this tool.
