Additional Information:

1. We recommend using brake booster/master cylinder combo 910-31978 with this front disc brake kit. Stock single reservoir 4-wheel drum brake master cylinders do not have the capacity to supply the proper amount of pressure for front disc brakes. Combo 910-31978 also includes an adjustable proportioning valve which is to be installed in the rear brake line circuit. The proportioning valve modulates pressure to the rear brakes which is necessary to prevent the rear brakes from locking up in an emergency stop situation.
2. We also suggest for your consideration the following related items to complete your installation:
   1. Upper control arm bolt and nut kit
   2. Lower control arm bolt kit
   3. Lock nuts for lower control arm (4 required)
