Disc Brakes- 8.5" 10 bolt axle (70-81 Camaro or 98-04 S10-Blazer )

To discuss this topic go here- LINK

I went to my local LKQ and picked up the parts I needed from a 98 - 04 S10 Blazer.
Below is a complete list of the parts you will need to do the conversion. Some parts you may already have but if not, its listed. Hope its helpful.

A comprehensive list of what needs to be done to go from factory rear drum on a
70-81 Camaro to 98-04 S10-Blazer rear disc.

Parts you will need:

1 - Driver side 4WD backing plate, e-brake assembly (GM PN-15064302)
1 - Passenger side 2WD backing plate, e-brake assembly (GM PN-15773309)
8 - 3/8 bolts, lock washers and nuts to mount backing plate to rear housing
3/8 washers to shim the backing plate for perfect fitment of the caliper to rotor
(2 each bolt in my case)
2 - Driver side 4WD caliper, or passenger side 2WD caliper, mix & match
(Loaded kit w/ brackets & pads Cardone PN-164712) (Loaded kit w/ brackets &
pads NAPA PN-TS 1422228)
2 - Caliper brackets - if needed
1 - Brake pad set - if needed (HAWK HB119F-594)
4 - caliper bracket bolts (GM PN-15726460)
2 - banjo bolts (GM PN-10286122)
2 - 2WD Blazer rotors (NAPA 4886725) (Powerslot 8638PSL & 8638PSR)
1 - Master cylinder (80 disc/disc T/A, 79 disc/disc Vette, 70 manual disc/disc
Vette all work)
2 - Brake hoses (you can use stock Blazer hoses or any braided stainless ones with
a 10mm banjo fitting)
1 - Prop valve (stock 80 T/A works, I used a Summit adjustable)
New style brake cable (I used the Blazer cables, but Lokar universal would be
less work)
Brake fluid, gear oil, axle seals
Somehow, the idiots survive despite their best efforts to kill themselves.
