You can Select Your Vehicle to check if 46540-06030 fits your vehicle.

Remove the brake disc. Inspect the shoe lining material's thickness; if worn down to 1/32-inch or less, replace the shoes. While you can replace the shoes without removing the hub and bearing assembly, space will be limited. Wash the brake parts with brake system cleaner before disassembling. For shoe replacement, follow this order: remove both the front and rear parking brake shoe return springs from their respective anchor pins and unhook them, take off the rear shoe hold-down spring and its pin, remove the shoe strut between the shoes, take out the front shoe hold-down spring and its pin, remove the adjuster and the tension spring, pop off the C-washer from the pivot pin on the rear shoe's back and detach the parking brake lever, apply high-temperature grease to the backing plate's contact surfaces and the front shoe's backside, slide the parking brake lever onto the pivot pin with a new C-washer, flip the shoes, install the adjuster ensuring its ends engage with the shoes, attach the tension spring to the rear shoe's backside, place the shoes in position, install the strut and its spring ensuring the strut's ends engage with the shoes, and finally, install both the front and rear shoe return springs followed by their respective hold-down springs. With the assembly done, install the brake disc and use three wheel lug nuts to secure it. Remove the hole plug from the disc and adjust the parking brake shoe clearance using a tool or screwdriver until shoe-disc contact prevents disc turning. Back off the adjuster by eight notches, then replace the hole plug, ensuring the shoes don't drag on the disc. Install the caliper mounting bracket, followed by the brake caliper, ensuring the bolts are tightened. Install the wheel, tightening the lug nuts. If your vehicle has a parking brake lever, it should travel between five and eight clicks when pulled. To bed the shoes to the drum, drive at 30 mph on a dry, level road. Apply the parking brake slightly, driving 1/4-mile like this, and repeat two or three times, letting the brakes cool in between.

Regular brake system inspections are crucial to identify issues promptly. Brake problems can manifest as vehicle pulling, noises, excessive pedal travel, pulsations, or fluid leaks. Early detection helps prevent costly damage and ensures safe operation.

Perform a brake booster check by starting the engine with the brake fully depressed and observing pedal movement. The pedal travel should remain consistent. Turn off the engine, hold the pedal for 30 seconds, and restart the engine to confirm decreased pedal travel with each subsequent application. Check the parking brake by counting clicks when engaging it with the handle or pedal. Adjust the parking brake if the click count deviates from the specified value. Alternatively, verify parking brake effectiveness on a steep hill in Neutral; if the vehicle rolls, perform parking brake adjustments.
