The piston transmits hydraulic pressure from the caliper body to the brake pad, clamping it against the disc to generate stopping force. Corrosion of the original piston - common on older calipers exposed to moisture and road debris - causes seized calipers, uneven pad wear, and reduced braking performance.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eManufactured from stainless steel, providing significantly greater corrosion resistance than standard mild steel or aluminium pistons\u003c\/li\u003e\n\u003cli\u003e41mm diameter, matching the original caliper bore specification for correct hydraulic function and pad contact\u003c\/li\u003e\n\u003cli\u003eDesigned to OEM dimensions for direct fitment without caliper modification\u003c\/li\u003e\n\u003cli\u003eWhen replacing pistons, inspect caliper seals and dust boots for wear and replace as required - new seals are recommended any time the piston is removed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Discovery 1 (1989–1998) and Range Rover Classic (up to VIN GA399973), on vehicles equipped with solid disc brakes requiring a 41mm diameter caliper piston.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
