You can Select Your Vehicle to check if BHKP7300 fits your vehicle.

It is imperative that parking brake shoes be changed a both wheels at the same time; never change shoes only on one wheel. The parking brake system should be checked often particularly when the vehicle is parked on an inclined plane through engaging the brake, shifting the gear to the neutral and then checking that the parking brake locks the vehicle again. It is, therefore, required that a visual inspection of the assembly be done every 24 months or any time a fault is suspected. Start with the removal of the rear wheel lug nuts, lifting of the vehicle up to the rear and placing it on jack-stands firmly. The parking brake must be released and the front wheels blocked and the rear wheels demounted. The rear calipers must be taken off while maintaining them by using a Bungee cord or heavy wire and without releasing the brake line. Then, first of all, it is necessary to remove the rear discs and the rear hub and bearing assemblies. The parking brake assembly should also be cleaned with brake system cleaner. When releasing the parking brake shoes, there are some general and specific steps for release of the hold-down clips and springs; one must closely look at the lining contact pattern to check for bending or improper adjustment. Treat the backing plate with the same solvent used to clean it and examine the drum also. Before installing the brake sparingly apply lubricant on the friction points on the brake backing plate, If the parking brake cable was removed, it should be inserted into the actuator lever, Next put the new shoes in place as explained in the steps used for fitting of the hold-down clips and springs into place. You should set the distance across the friction faces of the shoes to six and three-quarters inches as you put the disc on the shoes and make sure they can barely turn as you turn the disc, then move the adjuster backwards and forwards until this is so. Last but not the least; place the caliper and do the same thing you did for the other rear wheel.

Next, remove the rear calipers, but keep them supported with wire and avoid disconnecting the brake line. Proceed to remove the rear discs and the hub and bearing assemblies. Clean the parking brake assembly with brake system cleaner.
