1968 FJ45 rear Disc Brake Conversion Kit (JTO) oberservations needed

[melvinjo]

Al,

My Wife bought me a rear brake disc conversion kit from JTO out of NC. Now understand, my Wife makes minimum wage, so the price of almost $500 was a real sacrifice for her...Its a gift, and I do appreciate what she has done

To be honest though, I am NOT impressed with JTO: I have called thier number with basic questions in the past, and the folks that man thier phone lines are fairly short and abrasive.

My wife got the rear brake kit for my 68 off ebay thru thier ebay store this past winter: I did notice today that JTO no longer sells on ebay, whatever that might mean.....

My intent isnt to bash JTO as folks respond to my topic thread, but to get any install hints/observations from those that may have purchased the JTO rear disc conversion kit for thier 67/68 FJ45....

I havent installed the kit yet. but am about to start: But I would like any input from anyone who has a 68 FJ45 that has installed the JTO rear disc brake conversion kit: Im about to start the install, and would like any installation shortfalls/probs that anyone may have experienced

Plz understand, I am mechically inclined: But my limitations are that I can not run a master cylinder booster, but will install a proportioning valve

Specifc questions that I have:

1. I now have the drum brake, master cylinder with single reservior: Must I change to a dual reservior master cylinder: If so, what years/model could be used as a direct bolt on? (Remember, I will not run a booster)

2. Will my existing drum brake lines work? If I need to change, what size do I need to go, mm wise?

Again, any general input from those that have installed the JTO rear brake conversion kit on thier 68 FJ45 is highly appreciated

Thanks

First, I would not install discs on the rear unless you are also going to install them on the front. Think tail wagging the dog when you stop with a disc rear and drum front. To answer your questions. Yes, you will need to swap out the brake master and you will need to change out the flares on the rear hard lines to install the later larger flare fittings. I would either sell the JTO kit and keep what you have, or make the investment and source all that parts you will need to make the front disc also. I would personally swap out your single circuit system for a dual for safety reasons alone. People have used spacer / adapters and GM non boosted masters instead of cutting the rib for a booster with good results from what I have read here.

I beleve the JTO Kit already comes with the banjo adapters for the existing brake lines.

I'm in the process of doing a complete disc brake conversion on my 9/71 Landcruiser. IMO complete kits are a jip. I have just ordered their adapters brackets and misc. parts to do the conversion but I orderd the rest from the local autozone including a duel MC and saved a round $300 over JTO price.

I would cut the the firewall ribbing, install a booster and a dual cylinder master, though it may seem like a lot of work, others have done it successfully. I installed a JT Outfitters kit two weeks ago and only problem was solved with some grinding of the front hubs, nothing major. Do check that you have the OEM tires with no ribbeting on back otherwise I think you do have to grind the calipers somewhat.

Check my thread I do believe I posted some of those pictures there.

Check how someone cut the ribbing in the firewall and it worked:

Also, JT Outfitters still sells on eBay:
