Post by: OHEARN.2012 on January 16, 2011, 07:36:48 AM
ok so i have heard they are worth the money?? are they wat is your input? was looking through gearz's yukon sas and seen hegot the caliper mount brackets for 50 bucks whcih aint bad but wondered wat kind of calipers and rotors i would need and any special tools?? any instructions on how to take axle apart?? i checked prices and for new calipers and rotors its like 150-200  ==sick i know it would be better to get new but would it be worth it to go to local junkyard and pick some up?? i have use of a caliper recondtioning machine at tech center but would it be worth it?

you can get the brackets off ebay  pretty cheap.  thats where i got mine.  then you use an 8 lug rotor and caliper  off a 10 bolt front axle.   and 150-200 for new rotors and calipers????  where did you get that price.   i can get new calipers for 15-20 a piece and rotors for about 30 a piece  so  maybe 100  into 2 rotors and 2 calipers.     then whatever you wanna spend on pads.

and if it was me  i wouldnt bother going to a junk yard and gettin used stuff.   unless things are just that expensive wehre you live  you can get new  reconditioned calipers  for 15-20 a piece.  just not worth the time to go thru and do them myself

I did my 1985 Chevy many years ago.
Used all parts from a front axle.
First, I mounted rotor to rear axle hub with studs holding rotor to hub of front axle.
re-installed rear hub/rotor on axle.
bolted caliper to backing plate, cut as much as needed to fit backing plate to rear axle.
Lined up caliper to rotor (with new pads installed) (be sure bleeder is to top).
Welded backing plate to axle, with a couple re-inforcing gussets.
Never did, but a different porportioning valve would have been nice,
seemed like rear now needed more fluid volume with calipers.

Hope this helps.

what wild time is saying is exactly what i m doing   i m getting all stuff from a 77' chevy 8 lugs .. just use the rear hub from the drums and get  it on the rotor  and use 10 bolt or dana 44 calipers , get a backing plate or make one or buy one . and its  easy  to do  pirate4x4.com has it on their web i ll get u the link .. if u want whole new conversion i figured it ll be around $150- $175 depending where n how u re gonna get yr parts

a portioning valve off a late 80's caddy works good too.They had disk brakes on the rear,and it allowed the correct amount of fluid to the rear.
