Built from high-hardness carbon steel, the tool resists wear and deformation under repeated use. The 360° pivoting ratchet and reversible mechanism let you compress or expand pistons in tight spaces without removing the caliper entirely.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the 360° swing ratchet make caliper work easier?\u003c\/h3\u003e\n\n\u003cp\u003eThe pivoting head lets you angle the tool in confined wheel wells so you can apply even force to the piston face without slipping. Its ratchet mechanism provides controlled, incremental movement so you can advance or retract the plates with minimal effort.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e360° swivel allows multi-angle access in cramped brake assemblies\u003c\/li\u003e\n  \u003cli\u003eReversible ratchet switch for forward or reverse compression\u003c\/li\u003e\n  \u003cli\u003eWide contact area reduces risk of plate slippage on piston\u003c\/li\u003e\n  \u003cli\u003eLeverage design minimizes hand fatigue during repeated operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich caliper types are compatible with this spreader kit?\u003c\/h3\u003e\n\n\u003cp\u003eThis tool is designed for disc brake systems and works with single-piston, twin-piston (floating or fixed) and four-piston fixed calipers.

Use the hooks to hang rotors, hoses or hoses out of the work area, and apply lubricant sparingly to pad backs—do not lubricate piston faces or friction surfaces to avoid slippage or contamination.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eTwo steel plates for even piston pressure—squeeze plates together to operate\u003c\/li\u003e\n  \u003cli\u003eFour hooks keep discs, hoses and lines secured during service\u003c\/li\u003e\n  \u003cli\u003eLubricant bottles protect against rust and reduce squeal when applied to pad backs only\u003c\/li\u003e\n  \u003cli\u003eFollow the ratchet directional switch for expansion or compression control\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I operate the caliper compressor step-by-step?\u003c\/h3\u003e\n\n\u003cp\u003ePosition both steel plates across the piston face, set the ratchet direction to compress or expand, then advance the handle with steady shakes or ratcheting strokes until the piston is fully retracted.

It suits users who want a multi-angle ratchet solution with extras—hooks and lubricant—for safer, more organized brake jobs. Avoid using this kit on drum brake systems or where piston access is blocked; always follow manufacturer torque and brake-bleeding procedures after pad replacement.\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 this tool compress four-piston calipers?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the kit works with most fixed four-piston calipers using the included steel plates for even coverage.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is the lubricant safe on piston faces?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No — apply lubricant only to pad backs and metal contact points, not to piston or friction surfaces.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"hongdounangguo","offers":[{"title":"Default Title","offer_id":48087121297566,"sku":"B0F9KJCSYV","price":33.48,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/hongdounangguo-front-view-tool-kit.jpg?v=1785917092","url":"https:\/\/northtrailauto.ca\/products\/hongdounangguo-brake-caliper-compression-tool-kit-with-4","provider":"North Trail Auto","version":"1.0","type":"link"}
