The factory piston commonly cracks or loses its bond under heat and mileage, causing internal leakage that weakens brake apply — leading to flare on upshifts, slipping under load, and rapid clutch failure. This upgraded molded piston with permanently bonded rubber seal restores full line pressure, delivers crisp 4th \u0026amp; 5th gear performance, and protects your brake clutch pack for reliable daily driving or light towing.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003ePerfect fit for popular models including:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul dir=\"auto\"\u003e\n \t\u003cli\u003eMazda 3, 5, 6\u003c\/li\u003e\n \t\u003cli\u003eMazda Tribute\u003c\/li\u003e\n \t\u003cli\u003eFord Escape, Fusion\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eSymptoms of a failing reduction\/OD brake piston:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul dir=\"auto\"\u003e\n \t\u003cli\u003eFlare or slip on 4-5 upshift\u003c\/li\u003e\n \t\u003cli\u003eDelayed engagement in higher gears\u003c\/li\u003e\n \t\u003cli\u003eHarsh shifts when clutches finally grab\u003c\/li\u003e\n \t\u003cli\u003eBurnt reduction\/OD brake frictions on teardown\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"auto\"\u003eDon’t let a $50 piston destroy a $500 clutch pack — install the Stellar Automotive Group bonded reduction\/OD brake piston and shift strong through every gear.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e All parts are distributed, not designed or manufactured, by Stellar Automotive Group.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eAdd this critical FNR5 rebuild part to your cart today and keep higher gears locked in tight!\u003c\/p\u003e","brand":"Trans Parts Direct","offers":[{"title":"Default Title","offer_id":52425243820213,"sku":"46762C PAFT","price":37.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1006\/3872\/0181\/files\/46762C-PAFT-scaled.jpg?v=1786618861","url":"https:\/\/transpartsdirect.com\/products\/stellar-automotive-group-fnr5-reduction-od-brake-clutch-bonded-piston-fits-mazda","provider":"Trans Parts Direct","version":"1.0","type":"link"}
