This kit will allow you to use calipers on the rear disc brakes that do not have the parking brake built in them. This eliminates all the complications of having to set the parking brake frequently and running multiple cables. Especially on tubbed cars where the cables can't make the turn inward to clear the rims. This brake applies it's clamping force on an 8" rotor before it gets the torque reduction of the rear end ratio. Also works with rear drum brakes.
- Remove existing U-joint and girdles.
- Fit Rotor over yoke. It may be necessary to grind a very small amount at 4 points shown in picture below to be able to get the Rotor to fit over the yoke. The other option is to remove the yoke, install the Rotor, then put the yoke back on. Try to grind all 4 spots equally to keep rotational mass balanced.
- Put the supplied Moroso aluminum girdles and screws in yoke with out a u-joint present. It might be necessary to clean out or chase a thread tap thru your yoke to ensure good clean threads.
- Place rotor over the 4 girdle bolts sticking out of the yoke. Some round filling may be necessary to align the bolts thru the rotor mounting holes.
- Put the supplied 4 thin nuts over the screws to capture the rotor. The round pinion seal cover might be a little close. Simply wedge the nuts in, the cover will flex out of the way. Rotate the yoke and check for wobble in the rotor. Sometimes yoke castings are different and it could be necessary to True the rotor by either shimming between the rotor and the yoke or machine the backside of the yoke.
- Remove the 2 bolts holding the caliper together.
- Put the supplied tubes and long bolts on the caliper. (The side with the lever).
- Put the caliper tubes with the caliper thru the tubes in the bracket. Tighten the 2 nuts insuring the tubes assembled to the caliper slide freely with in the tubes of the bracket.
- The nut on the back of the caliper adjusts the pads. Open adjustment of caliper pads and place caliper and bracket over the rotor.
- Take out adjustment in caliper pads and pull lever to clamp rotor in place. Slide bracket away from rotor until the bracket is about 1/8” from the closest point of the bracket arch and the rear housing.
- Use small c-clamps to hold bracket in it’s mounting position.
- Match drill 4 clearance holes for 5/16” bolts in fins of rear housing and bracket mounting tabs.
- Install all 4 supplied mounting bolts.
- Once pre assemble is completed, disassemble everything.
- Slip rotor over yoke.
- Attach u-joint and drive shaft.
- Assemble the girdles as specified by Moroso.
- Mount the rotor to the girdle bolts, apply lock tight to thin nuts and tighten.
- Put caliper and bracket assembly over rotor again and install all 4 supplied mounting bolts from the top, and put the lock nuts from the girdle kit on the bottom. The bolts are polymer coated Cadmium-plated grade 8 high-strength steel.
- Adjust caliper pads and add your own parking brake cable. Since the cable has to make a 90 degree turn the easiest way to hook up a cable is to use an enclosed cable like a motorcycle cable. Be sure to have a return spring feature. With the cable hooked up, it should be adjusted to fully release when the emergency brake lever is off. Adjust the pads as loose as possible. If the brake doesn’t lock up the rotor when it is applied try using the lower hole in the caliper arm, this will give more movement to the pads.
