I have done this and it works very well and
is cheep/ easy.... I recommend this to any
one who wants more stopping power.. I
have used this system and total cost for me with used rotors and calipers was less than $200.00.
The stopping power is unbelievable...Rene
******************************
Instructions for all other models-(Other than GM that is)-
Remove all of the old drum brake parts including the backing plate that
holds the brake shoes etc.
If you have TAPERED axles that use shims to set end play
(Studebaker, Dana, AMC) then you must pull
the hubs off the axles.
On later FLANGED axle Dana, Ford 8 in and 9 in, you
will have to slide the axles out in order to remove the drum brake
backing plates.
The new brackets are to be mounted so the calipers
will be above and to the rear of the rear axle.
Mount the rear brackets on the INBOARD side
of the axle housing flange. (behind the flange where the old brake backing
plate used to be)
With some bracket assemblies that have spacers attached to
the brackets, you can attain different offsets to accommodate different
rotors and axles by trading right side and left side brackets.
For some installations the brackets will be
mounted so the spacers will be directly against the housing flange.
Others will require that the bracket itself
be mounted so that it is
against the flange, leaving the spacers extending to the inboard side of
the bracket (swap right side bracket for left side bracket).
You can tell easily if you have the right
spacing if the INBOARD brake pad fits well between the bracket and the
rotor surface. If you have too little room to slip in a brake pad; then
you need the spacer side of the bracket against the housing.
IMPORTANT- on C-Clip rear ends (8.8 + 7.5 Ford,
and many GM) you MUST have the axles in the correct position as if they
were completely assembled, or the bracket offset will have to be changed
when they are finished. (the axles will move outboard some, after the
c-clips and center pin are installed)
/////////////////////////////////////////////
Use 1985 Cadillac Seville rear calipers with built in parking brakes. GM
front "Metric" calipers (mid 80's) will fit the brackets, but fronts do
not have the parking brake.
The same GM cars will supply the pads, guide pins etc.
/////////////////////////////////////////////
The rear rotors to use for the Dana 44, Dana 27, Ford
8 inch, and Ford 9 inch are-
For the large 5 on 5 inch bolt circle- use 1977 Lincoln and
Continental REAR rotors.
For the 5 on 4-1/2 inch "regular Ford" bolt circle, use the 1985 Lincoln
Mark7 rear rotors.
/////////////////////////////////////////////
With the Studebaker Dana 44 and 27 rears, use Dorman #
610-132 studs to replace the stock studs when using the re drilled 5 in
circle 1977 Lincoln rotors.
OR use the Dorman #610-085 studs for the 4-1/2 inch car bolt circle when
using the 1985 MK7 rotors on Studebaker.
//////////////////////////////////////////////
The rotors to use with the early+ mid 1980's on up Ford Mustang, Ranger,
and others using the 7.5 and 8.8 rear ends-
For the
4-lug (4-1/4 bolt circle) use the 1988 Turbo Coupe rear rotor.
For the 5-lug (4-1/2 circle) use the 1985 MK VII (mark 7) rear rotors. I
have been told by two Mustang owners that they have switched from 4-lug
to 5-lug by using TWO Driver side Ranger axles in their Mustang
housings- I have not done that myself.
//////////////////////////////////////////////
If you choose to buy the incidental parts (levers, return springs) from
a junkyard GM rear disc car you can save on price. If you want NEW GM
parts, then here are the GM part numbers-
Return Spring Bracket and Bolt--
GM-18005312-Left
GM-18005311-Right
Return Spring (need 2) - GM-180055822
E-Brake Levers-
GM-18003044-Left
GM-18003045-Right
10MM Banjo Bolts.
Brake Hose- Either mid 80's Camaro, Cad or Wagner part # F97661 Subject:
brakes+ parts The brake kit uses mid 80's and mid 90's Cadillac
calipers, and Lincoln rear rotors.
I recently bought some1985 Cad Seville rear calipers with built in
parking brakes from Car Quest for $67 each. That may sound pricey, but it
includes the parking brakes.
I bought the1985 Lincoln MK7 rear rotors for $68 each at Auto Zone. You
can either get the return springs, P-brake levers, etc from a salvage
yard for a few dollars or go to a GM dealer and buy them new for around
$80
Lokar has a universal parking brake cable kit
for around $80.00 if you need a new one. Using these OEM parts is the
lowest cost way to get rear disc brakes if you compare to the other
non-OEM brake suppliers.
//////////////////////////////////////////////
Here is a tip to save you $$$$
You can save $160- $200 by getting Cad caliper cores from
selectcore.com or a local junkyard ($75?), keeping the levers ect, then
using the calipers as trade-ins
ANSWERS TO COMMON QUESTIONS-
A couple customers have said that they spent around $320-$350 on their
disc conversion. I spent about $400 on mine
(9 inch swap) That is a
whole lot less than the usual
$600-$900 spent with other methods.
Use 1980 - 85 Cadillac (Seville, El Dorado etc) rear calipers with the
built in parking brakes.
I use 1985 Seville calipers on mine because I like the way that
the e-brake cables run along the leaf springs along the original drum
brake cable path.
