The Lisle 29100 is a compact, purpose-built plate spreader that pushes piston faces back into the caliper housing while keeping pads separated, so new pads fit without forcing or risk of damage. It works whether the caliper is still mounted on the vehicle or removed and hanging free, streamlining both DIY and professional brake service work.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Quick Quad make brake pad replacement faster?\u003c\/h3\u003e\n\u003cp\u003eThe tool compresses pistons and spreads pads in one operation, removing the need for multiple tools or repeated adjustments.

The Lisle 29100 Quick Quad Pad Spreader is aimed at mechanics, restoration hobbyists, and DIY vehicle owners who service disc brakes with multi-piston calipers. It’s especially useful for shops and home garages that handle four-piston calipers regularly and want a faster, safer way to retract pistons and seat new pads without resorting to makeshift levers or multiple tools. If you need a reliable, compact spreader that preserves pad and piston condition while reducing service time, the Lisle 29100 is built to fit into your toolkit.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can the Quick Quad be used with the caliper still on the car?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the Lisle 29100 is designed to compress pistons while the caliper is mounted or hanging free.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What maximum spread and reach does the tool provide?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It spreads up to 2 1\/2\" with a plate width of 3 3\/4\" and a 1 7\/8\" reach to the outrigger arm.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Lisle","offers":[{"title":"Default Title","offer_id":48079812559006,"sku":"B005GLQCKA","price":93.17,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/lisle-29100-front-view.jpg?v=1785771452","url":"https:\/\/northtrailauto.ca\/products\/lisle-quick-quad-pad-spreader-29100-4-piston-brake-caliper-tool-compact-plate-design","provider":"North Trail Auto","version":"1.0","type":"link"}
