A bent or re-drilled bracket pulls the pads on at an angle, and you get a lever that feels wooden plus a disc that wears on one side. This part ships as a matched caliper-and-bracket set, so the pad-to-disc alignment is correct from the first bolt.\u003c\/p\u003e\u003ch3\u003eWhen to replace your caliper\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBraking feels weak or spongy even after adjusting the cable tension\u003c\/li\u003e\n\u003cli\u003ePads drag constantly, or rub on one side of the disc\u003c\/li\u003e\n\u003cli\u003eThe caliper body is cracked or bent, or the pad adjustment screw is maxed out\u003c\/li\u003e\n\u003cli\u003eUneven pad wear — one pad worn to the metal, the other barely touched\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitting notes\u003c\/h3\u003e\u003col\u003e\n\u003cli\u003eSupport the scooter so the wheel spins freely, then unbolt the old caliper and bracket.\u003c\/li\u003e\n\u003cli\u003eBolt the new bracket on first, then set the caliper loosely so it can self-centre.\u003c\/li\u003e\n\u003cli\u003eSqueeze the lever to centre the caliper over the rotor and tighten the bolts evenly.\u003c\/li\u003e\n\u003cli\u003eSet cable tension so the pads clear the disc by roughly 0.3 mm, and check the brake cut-off stops the motor.\u003c\/li\u003e\n\u003cli\u003eBed in the pads with 20-30 gentle stops from moderate speed before riding fast.\u003c\/li\u003e\n\u003c\/ol\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eDesigned for the SUNNIGOO N3 series (N3 \/ N3MAX \/ N3LMAX with 10-inch wheels and 140 mm rotor).
