Installation Instructions:

1. Disconnect the rear driveline by removing the (4) bolts holding the rear driveline to the transfer case rear output flange. Using a chisel, unstake the output flange nut. Loosen the output flange nut and remove the nut, washer, and output flange from the transfer case.

2. Remove the dust cover from the back side of the output flange and then assem­ble the provided brake rotor, output flange, and dust cover as shown. The brake rotor should be on the transfer case side of the flange.

3. Ensure that the appropriate bolt pattern on the rotor and output flange are aligned. This bolt pattern will be the same bolt pattern used on the yoke of the rear driveline. It helps to mark the rotor and output flange at this point to make them easy to align later.

4. Slide the flange assembly onto the rear output shaft of the transfer case and apply Loctite thread locking compound to the output shaft threads. Reinstall the output flange washer and nut. Torque the nut to the appropriate torque spec as found in the vehicle's service manual. Stake the nut.

5. Align the holes in the driveshaft with the holes in the output flange and the brake rotor. Install the (4) provided M10x35MM long bolts, lock washers, and nuts as shown. Gradually tighten the bolts ensuring that there are no gaps between the driveshaft yoke, output flange, and rotor when you are done.

6. Bolt the E-brake arm to the main mounting bracket as shown using the provided 3/8" hardware and plastic spacer washers. It is important to place (1) plastic spacer washer between the metal 3/8" washers and the arm/mounting bracket. The remaining (3) plastic spacer washers should be installed between the E-brake arm and the main mounting brack­et. Tighten the lock nut until the arm is snug against the mounting bracket but you are still able to rotate the arm freely.

7. Attach one end of the arm return spring to the E-brake arm and the other end to one of the spring holes in the mounting bracket as shown. Multiple holes are provid­ed to adjust the tension of the return spring. When the spring is hooked on both ends the arm should be fairly easy to move but should easily rotate until it contacts the tab that is bent upwards on the mounting bracket.

8. Assemble the brake caliper, all thread rod, jam nuts, and clevis joints as shown. It may be necessary to switch the side of the brake caliper lever to the side shown. If necessary, consult the Caliper Lever Reorientation instructions available on the All-Pro Off-Road website. Adjust the length of the all thread rod until there is about 3.5" between the two jam nuts. Do not tighten the jam nuts yet.

9. Attach the free clevis joint to the E-brake arm as shown. Slide the caliper into the mounting slots of the main mounting bracket. Loosen the lock nut on the adjustment screw of the brake caliper and then unscrew the adjustment screw until there are only a few threads of the screw in the caliper.

10. Remove the (5) bolts as shown from the transfer case.

11. Take the caliper, E-brake arm, and mounting bracket assembly to the underside of the vehicle. With the whole mounting bracket on the transfer case side of the rotor slide the brake caliper over the rotor and then align the mounting holes in the bracket with the holes in the transfer case.

12. Install the (4) supplied M1 0x45MM long bolts and the (1) M10x100MM with the supplied lock and flat washers. Insert the supplied spacer between the back of the mounting bracket and the transfer case as shown. Once all the bolts are started into the transfer case, tighten the bolts to the appropriate torque spec as found in the vehicle's service manual.

13.Make sure that the all thread rod is loose between the brake caliper and the E-brake arm. If there is tension on the all thread rod it may be necessary to disconnect one of the clevis joints and extend or shorten the all thread rod. With the brake caliper lever rotated fully downward (clockwise}, finger tighten the adjustment screw of the brake caliper until the screw compresses the pads against the rotor. While holding the adjustment screw in place, tighten the adjustment screw lock nut against the brake caliper.

14. Verify that the driveshaft and the rotor can freely rotate with minimal drag from the brake caliper. If you cannot rotate the driveshaft by hand loosen the adjustment screw on the brake caliper and check again.

15.Verify again that the linkage is loose between the brake caliper and the E-brake arm. If the linkage is not put­ting any pressure on the caliper tighten the jam nuts on the all thread rod.

16. Remove the factory locking clip and E-brake pin from the factory E-brake mecha­nism. Remove the pin from the factory mechanism and then install the E-brake cable, pin, and locking clip onto the new E-brake arm as shown.

17. Test the E-brake by pulling the E-brake handle in the cab. It should only take 2-3 clicks before the E-brake is tight. Start the vehicle, put the transmission in first gear (or drive for an automatic transmission), and the transfer case in 2WD high range. For a manual transmission, when you let off the clutch the engine should stall. For an automatic transmission, when you let off the brake the vehicle should stay stationary. If the vehicle moves a large amount tighten the adjustment screw on the brake caliper and retest.

86-95 Suzuki Samurai E-Brake Caliper Lever Reorientation

Some of these calipers that were supplied in our kits have the lever oriented incorrectly. These instructions will show how to reorient the lever so that it will work with our E-Brake kit.

Step 1: Remove the (2) through bolts by holding the bolt with a 9/16" box end wrench and turning the nut using a 9/16" socket. Separate the two housings.

Step 2: Remove the pad from caliper housing #1. Remove the pad plate.

Step 3: Remove the actuator pin. Then remove the adjustment bolt and lock nut.

NOTE: It may be necessary to loosen the lock nut with an 11/16" open end wrench and remove the adjustment bolt with a 3/8" open end wrench.

Step 4: Open the bench vice jaws about 1/2" apart. Place a cloth over the vice to protect the caliper. Place the caliper on the vice with the pin centered in the opening of the vice jaws. Using a 3/16" punch and a hammer, drive the pivot pin out of the caliper housing. Next remove the lever.

Step 5: Turn caliper housing #1 over and insert the pivot pin (half way only) in the other hole. Install the lever with the arrow and the sharp notch pointing away from you.

NOTE: Insure that caliper housing #1 is oriented exactly the way this one is in the picture.

Step 6: Continue installing the pin until it engages the proper hole in the lever. Then place caliper housing #1 on a solid flat surface and drive in the pin the rest of the way.

Tech Tip: It may be necessary to recess the pin using a hammer and punch. This shows the lever and pin properly installed.

NOTE: See that the arrow on the lever is pointing away from you. If it is not something is wrong and must be fixed before continuing.

Step 7: Reinstall the adjustment bolt and lock nut. Leave the bolt and nut loose for now. Turn caliper housing #1 over.

Step 9: Install the pad and secure the pad, plate, and pin in place using masking tape.

Note: This will keep these parts from falling out during the reassembly and installation process.

Step 10: Place caliper housing #2 on top of the caliper housing #1 and install both bolts. While holding both caliper halves and through bolts in place, turn the assembly over and apply red thread locker to the threads of both bolts.

Step 11: Install the nuts. Hold the bolt with a box end wrench and tighten the nut with a socket. Once both nuts are tight, torque them to 25 ft. lbs.

Note: If you are working alone you may want to clamp a 9/16" box end wrench in the vice to make tightening the nuts easier.

Step 12: Remove the masking tape. Note: This is what the caliper should look like when ready to install.
