Hyundai 58411-3Y300 Disc-Rear Brake

You can Select Your Vehicle to check if 58411-3Y300 fits your vehicle.

This procedure applies to both the front and rear brake discs on vehicles so equipped. Begin by loosening the wheel lug nuts, raising the vehicle, and securely supporting it on jackstands before removing the wheel. If inspecting the rear disc, release the parking brake. Next, remove the brake caliper without disconnecting the brake hose and suspend it out of the way with a piece of wire. Visually inspect the disc surface for scoring or damage; while light scratches and shallow grooves are normal, deep scoring necessitates refinishing by an automotive machine shop. Check both sides of the disc. If pulsation during braking is noted, suspect disc runout and check it using a dial indicator placed about 1/2-inch from the outer edge of the disc. Ensure the disc retaining screws or lug nuts are tight, then rotate the disc and monitor the runout; if it exceeds the maximum allowable limit, the disc must be machined or replaced. It is advisable to resurface the discs regardless of the dial indicator reading to ensure a smooth finish and flat surface, which helps eliminate brake pedal pulsation. If not resurfacing, remove any glazing from the surface with emery cloth or sandpaper using a swirling motion. It is critical that the disc not be machined to a thickness less than the minimum allowable thickness, which is typically stamped on the disc; use a micrometer to check the thickness at several points. For removal, if not already done, take off the brake caliper without disconnecting the brake hose and also remove the caliper mounting bracket. For 2000 or earlier models, remove the steering knuckle and have the hub flange pressed out of the knuckle to unbolt the disc from the hub. For 2001 or later models, simply slide the disc off the hub flange. On rear disc brakes, remove the retaining screw and take the disc off the hub. Installation is the reverse of removal; tighten the mounting bracket and caliper bolts, install the wheel, lower the vehicle, and tighten the lug nuts. Depress the brake pedal a few times to bring the brake pads into contact with the disc, and check the operation of the brakes carefully before placing the vehicle into normal service.
