  • Secure the vehicle on the flat surface so that you don’t have any difficulty while working.
  • Before lifting the front of the vehicle, put logs or wooden block behind the rear wheels.
  • Support the vehicle on the jack stands. It is necessary for your safety as floor jack is not something on which you can rely alone.
  • >Take the front wheels of the vehicle away by removing the lug nuts.
  • Look for the brake caliper and unfasten the bolts or pins holding the brake caliper.
  • Turn the caliper round and take it away from the brake disc. Never let the caliper hang by the brake hose instead support it to the coil spring with bungee cord.
  • Next, you have to discard the brake disc and hub assembly. For this, use channel-lock pliers to disconnect the dust cap. Then, discard the cotter pin and retaining ring.
  • Take the wheel bearing adjusting nut and washer away. Discard the disc assembly, then out wheel bearing and lastly, inner wheel bearing and grease seal.
  • Apply grease on the inner side of the new disc hub. Before applying grease, make sure that the surface of the disc is free from all sort of debris and dirt. Apply grease to the inner wheel bearing and fix it to the inner side of the brake disc hub. Also, use new grease seal.
  • Now, glide the brake disc assembly onto the spindle and assemble the outer wheel bearing coated with grease to the disc hub.
  • Secure the wheel bearing with adjusting nut and washer.
  • Use the adjusting nut to tune the free play of the wheel bearing.
  • Once the adjustment is done, reinstall the retaining nut and cotter pin. Put the wheel bearing dust cup back to its position.
  • Now, glide the brake caliper onto the new brake disc. Secure the caliper with mounting bolts or pins.
  • If rubber boots are required, install them now.
  • You need to repeat the steps from 4 to 15 on the other side as well.
  • Put the wheels back to the vehicle and secure them properly with lug nuts.
