12" REAR DISC CONVERSION KIT, 10-12 BOLT (RWBK101212) 19182

Part #RWBK101212

STEPS:  READ THESE INSTRUCTIONS CAREFULLY!
IMPORTANT:  THE ORIGINAL WHEELS MAY NOT FIT. PLEASE MAKE SURE TO CHECK WHEELS BEFORE ASSEMBLY, THIS WAY YOU WONT BE DISAPPOINTED IF THEY DO NOT FIT.

  1. Jack rear of vehicle and support the axle with jack stands.
  2. Remove the wheels, brake drums, axles and backing plate assembly.
  3. Clean and prep the mounting flange area of rear end.
  4. Mount the caliper bracket onto the outside of the rear end housing flange using the supplied bolts. (Note: the brackets should face the rear of the vehicle and the spacers supplied with the bracket should be between the caliper bracket and mounting flange) See diagram.
  5. Reinstall the axles with the new rotors attached. (Secure the rotor to the axle by using two of the lug nuts you took off). At this point install the calipers and check for clearance. NOTE: YOU MAY NEED TO FILE THE SPACERS SUPPLIED WITH THE CALIPER BRACKET TO GET PROPER CLEARANCE. THIS IS NORMAL DUE TO AXLE FLANGE VARIATIONS. NOTE2: IN SOME CASES THE AXLE FLANGE MAY NEED TO BE TURNED DOWN SO  ROTOR WILL FIT OVER IT. THIS CAN BE DONE WITH A HAND GRINDER, BUT IT IS RECOMMENDED YOU TAKE THE AXLES TO A MACHINE SHOP.
  6. Once proper clearance is obtained, be sure to torque all bolts. Mounting bolts need to be torqued to 50ft/lbs. dry or 35ft/lbs. lubricated. Caliper bolts should be torqued to 55 ft/lbs. loctite is recommended.
  7. Install brake hose. Double check all parts for interference and bolts for tightness.
  8. Install emergency brake cables. Make sure the end with the rectangular slot mounts fully onto caliper lever. Due to manufacturing variances you may need to fit the E-brake cable to caliper lever! (Proceed to bleed brake system).

RECOMMENDATIONS

  1. We highly recommend that you upgrade to a power brake booster assembly. The kits are available in 4 wheel disc configurations, Call for Details!!
  2. We also offer disc brake master cylinders proportioning valves and master cylinder adapter brackets for those who do not want to run power brakes! Call for Details.

    Hi, does this fit a 1970 Camaro 12bolt? Regards Trond.

      Hello, Yes this kit will fit your 1970 Camaro. However, your Camaro utilizes a staggered shock
      system. Make sure you specify that you need a staggered disc brake kit when ordering.

    What is the difference between the staggered and non-staggered brake kit?

    Thanks

      Basically the staggered rear disc brake kit uses 2 right hand brake calipers. The right side caliper mounts traditionally to the rear
      of the rearend where the left side caliper mounts to the front side as opposed to the rear side of the rearend.
