1971-87 CHEVY TRUCK, REAR DISC BRAKE WHEEL KIT, 5-LUG (RWBK-5-7187)

Part #RWBK-5-7187

Steps: Read these instructions carefully!
IMPORTANT: THIS KIT CONTAINS 12” ROTORS, THE ORIGINAL WHEELS MAY NOT FIT. PLEASE MAKE SURE TO CHECK WHEELS BEFORE ASSEMBLY, THIS WAY YOU WON’T BE DISAPPOINTED IF THEY DO NOT FIT.

  1. Jack rear of truck 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 inside of the axle flange using the supplied bolts. (Note: the brackets should face the rear of the truck and the spacers on 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 1:  You may need to file the spacers on the caliper bracket to get proper clearance. This is normal due to axle flange variations.
    NOTE 2:  In some cases the axle flange may need to be turned down so rotors 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 50 ft/lbs dry or 35 ft/lbs
    lubricated.
  7. Install brake hose. Double check all parts for interference and bolts for tightness. Proceed to bleed brake system.

      We have a rear disc brake conversion kit for this available. It includes the 11.5″ rotors and the calipers have a built in parking brake setup. The bolt pattern is 5 x 5″ which is factory. Cost is $975.00. Please contact us if you are interested in getting the kit. Thanks for contacting us.

    Have an 82 C10 Chvey 2 wheel drive and I’m looking for a disc brake kit for the rear end and would like to now how much does a kit like this run and how hard is it to install.

    • admin says:

      The kit cost starts at $549.99 depending on what options and components you want. The kit is extremely easy to install. Should be able to install using basic hand tools. Backing plates will have to be removed.

    have a 58 Chevy Pick up with a Pontiac 9.3 rear end 5 on 5, I want to put rear disc on it. Would this set work, and if so what rotors are used with this set?

    Looks like my 1986 GMC S-15 has the 5X5 lug bolt pattern & has room for the 12″ rotor. The only question now is, will this kit fit? Thanks….Dan.
