24-10A  DISC BRAKE UPGRADE KIT……....................…………………………........…..$785.50

Finally, a bolt-on disc brake upgrade kit for all Four-Wheel Drive Willys and Kaiser Jeep vehicles with Dana model 25/27 and 44 front axles.  This kit can also be installed on the rear axles of the MB/GPW and early CJ-2A vehicles with the Dana model 23-2 full floating rear axle. Vehicle front axle applications include the MB/GPW/CJ-2A/CJ-3A/CJ-3B/CJ-5/CJ-6/M38/M38A1/FC-150/FC-170 and all 4x4 Utility Wagons and Trucks.  This kit can also be installed on Kaiser Jeep vehicles to include the CJ-5/6/Jeepster/J-Series trucks and Wagons.  This kit can be installed on other vehicles using the above listed axles such as the International Scout.

This kit will offer you greatly decreased pedal effort with a very smooth and highly improved braking performance.  With the addition of our 11” rear brake upgrade kit you will experience braking performance never before realized on the early Jeep vehicles.

The installation is simple and requires no special tools.  There is no cutting, welding or permanent alteration to your vehicle.  The kit can be easily removed and your original system reinstalled.  The kit allows for the use of original 15” and 16” stock wheels as well as most aftermarket wheels.

This upgrade kit is complete with all new parts necessary for the installation and detailed instructions are included.  The kit can be installed in a matter of hours and all individual replacement parts other than the patented mounting brackets can be ordered individually.

Our disc brake upgrade kit includes a complete front hub service kit to include new front hub seals, wheel bearing nuts and lock washers and drive flange gaskets.  When ordering this kit it might be perfect timing to inspect the condition of your steering knuckle seals, king pin bearings, spindle bushings, wheel bearings and locking hubs.

The only variables in this installation will be with the front brake hose length.  Most early ¼-tons to include the MB/GPW/CJ-2A/CJ-3A/CJ-3B/CJ-5/CJ-6/M38 and M38-A1 use a short 6” front brake hose that attaches to a bracket on the front axle housing.  Later CJ-3B/CJ-5/CJ-6 vehicles and all FC-150/FC-170 vehicles and Utility Wagons and Trucks use a long 11’ front brake hose that attaches to a bracket on the frame above the front axle. Our kit includes two hoses that are 14 1/2" long which will cover all stock vehicles. Longer hoses can be supplied by most auto parts stores.

Our Disc Brake Upgrade Kit includes all of the parts shown below:

DISC BRAKE UPGRADE KIT  INSTALLATION GUIDE

This is a simplified guide to illustrate how easy it is to install this kit.  Complete detailed instructions are included with the kit.

Unpack your new kit. Make sure that all parts listed on the enclosed parts check list are present.

1.  Remove front wheels and front axle drive flanges or locking hubs.

2.  Remove front axle wheel hub and drum assemblies.

3.  Remove front axle spindles.  Clean and inspect them for wear and condition of the inner spindle bushings.

4.  Remove front axle hubs from the brake drums.  Clean and inspect the hubs and condition of the front hub wheel bearings.  Inspect the steering knuckles, steering knuckle seals and king pin bearings.  Any play in the king pin bearings indicates excessive wear and replacement is due. Any play at all indicates worn king pin bearings which will account for front wheel shimmy, loose sloppy steering and a dangerous driving condition.

5.  Install the front axle hubs onto the outside of the new disc brake rotors using the new longer wheel bolts. If you don't place the rotor behind the hub the calipers will not line up with the rotors.

6.  Install the spindles and the supplied disc brake caliper mounting brackets onto the steering knuckles using the supplied special bolts and lock washers taking note as to the correct positioning of the mounting brackets. The "wings" will point to the rear of the vehicle.

7. In order to provide clearance for the caliper, you will need to grind a little material off of the steering knuckle. With the caliper mounting bracket on the spindle, you can get an idea of how much grinding will be necessary to fit the caliper. Remember that as the pads wear out, the caliper will move inward because of its floating design. If you don’t grind enough, your caliper may hit the knuckle and render your brakes useless. Replace the steering knuckle fill plugs with the flush mount ones. Now you can start grinding the knuckle between the two bolts that are farthest to the back of the knuckle. You don’t have to remove a lot of material, but make sure you have good clearance by periodically replacing the caliper mounting bracket and caliper for test fitting. Also, grind the caliper a little to make sure that there will be no contact between it and the steering knuckle as the pads wear out, be careful not to grind through the casting.

8. Service the steering knuckles with gear oil or grease and install the supplied flush head knuckle fill plugs.

9.  Install the hub and rotor assemblies after servicing the inner and outer wheel bearings and installing the supplied inner hub seals. Adjust the wheel bearings with the supplied adjusting nuts and lock washers using the supplied wheel hub adjusting nut socket PN W-144.

10.  Install the front wheel drive flanges or locking hubs using the new supplied hub drive flange gaskets.

11.  Install the caliper assemblies on the caliper mounting brackets.

12.  Install the supplied disc brake pads.

13.  Install the supplied front brake hoses taking note as to the correct hose length required, depending on vehicle specifications, front axle attachment or frame attachment.

14.  Install front wheels and determine if wheel spacers are required. Wheel spacers can be supplied by most auto parts stores.

15.  Service and bleed the hydraulic brake system and test drive your vehicle. Break-in your new Disc Brake Upgrade Kit in accordance with the detailed instructions supplied in the kit and enjoy!
