STEP 2.    Remove wheel, hub and backing plate assembly.

STEP 3.    Clean the suspension upright and spindle carefully. Make sure the holes that align the adapter to the suspension upright are free of dirt from in back as well as the front.

STEP 4.    As you know should have a clear look at the condition of your suspension, inspect for any wear or cracks in the upright and bushings. If possible make the correction at this time.

STEP 5.    Take three of the button head screws and place them through the holes   (the 4 holes around the spindle, only 3 are used, the top rear and both front). Now take 16 of the washers and carefully place 4 each onto the bolts from the back side. Slide them tight up against the back side of the spindle flange. Now with either hand place a finger on top of each bolt head while sliding the adapter bracket on from the back side over the bolts (note, you will notice the two threaded holes in the adapter are now facing the front of the car).

STEP 6.    Place the locking nuts on the bolts and tighten with a ½-inch socket and 3/16-inch Allen wrench (Allen wrench is included in kit).

STEP 7.    Place the Spridget hub and rotor assembly on spindle and tighten spindle nut as per workshop manual instructions. Check for contact of rotor (disc) rubbing against button head screws because of castings roughness some rotors lack enough clearance at the radius inside the rotor. This needs to be machined to clear. UNDER NO CIRCUMSTANCE SHOULD THIS BE LEFT TO WEAR IN. THE HUB MUST TURN FREE.

STEP 8.    Place caliper over rotor and bolt it to adapter using two of the 7/16 -inch bolts provided in the kit with lock washers. Turn the hub to insure there is no interference with caliper body.

STEP 9.    CAUTION: At this point check to see that the caliper is centered evenly between caliper pistons and rotor. This is important, to achieve even pressure applied to both sides of rotor and not allowing one or the other piston to travel out of its bore (leaks and possible sticking of piston would be the result). If needed, washers could be taken from the button head bolts to equal out the spacing. If more are needed, washers of equal thickness are required. Always use an equal number of washers per each bolt. This maintains parallelism of caliper and rotor.

STEP 10.    Finish assembling and retighten hub, if removed. Connect hoses (don t forget the copper sealing washer). Recheck your work and bleed hydraulic system.

STEP 11.    Replace wheels, step on brake
pedal hard to check for pressure. A short run-in time is usually required for
maximum braking efficiency.
