Can’t stop your Land Cruiser? Tired of adjusting to keep them stopping straight? Outraged at the high price of drum brake parts? So were we, so we came up with JT Outfitter’s front disc brake conversion kit.  This conversion kit will allow you to remove and replace your old, inadequate drum brake set with a superior disc brake set.  This conversion was designed for use on 8/70 to 9/75 FJ40 or 55 (may work on early years but brake line fittings are different and you will need a dual circuit hydraulic system).

There are several ways to convert your axle to disc brakes, but we think this is the simplest and least expensive.  Popular ways include swapping another axle in (flanges rarely match and you still have worn used components) or  Mini-Truck / FJ60 Swap (hours of labor, trip to the machine shop for the knuckle arms or shimming, grinding considerable amount of metal off your axle housing, diving into the birfield, tie rod end incompatibility, and still worn used components.  You can always stick with drums, $70 per wheel cylinder (the good ones from Toyota, not the Taiwan leakers), $100 per drum, shoes, springs, lines, and more.  This will add up to about $600 to do right and you still have drums.

This is a complete kit to convert from your current drum brake system.  You get the powder coated backing plates, vented rotors, loaded calipers, hoses, and all the hardware.  One great idea was keeping this kit simple.  We used the same components as the common rear disc brake conversion.  This means simple inexpensive maintenance, trail spares are kept at a minimum, and anywhere anytime availability.  The magic is our bracket.  This represents much design and test work, and finally after several runs we are able to offer a strong, powdercoated, CNC laser-cut, caliper bracket that bolts to your existing knuckle house at the spindle. There is nothing in this kit besides our bracket that connot be replaced at your local auto parts store. We have sold literally hundreds of these kits with many happy customers.

Early Land Cruisers, those prior to 7/70, are 9mm fittings.  This kits is designed with 10mm fittings.  Also, early models have a single circuit, meaning one plunger pushes all the fluid for the entire system.  Upgrading to a dual system will improve performance of this system with ANY brake systems (ours or others).  To do this you will need a dual circuit master and to replumb your brake system.  More than likely, your system is nearly 40 years old, so replacing it is not a bad idea.  You will need to send one circuit to the rear, one to the front and split on top of the axles.

This kit fits with most wheels, although it is impossible to tell for all of them.  We have not encountered a problem.  Will not fit drum brake hubcap stock wheels, but we have sold literally hundreds of kits.  There are two kinds of wheels, rivets wheels and welded wheels, we tend to think that the welded ones will fit and maybe the riveted do not.

We grind each set of calipers before we send them out.  Occasionally, we may not grind enough off.  For the vast majority of occasions that will aleve any fitting issues.  The tab on the round part of the caliper needs to be ground flush as does one side of the opening where the hose hooks up.  You will see where we have ground them.  If it needs more then you can do this easily with a hand grinder.
