Trackick Build List

I'm currently working through Brennan's Garage excellent Trackick brake conversion on the m38. The kit from Brennan is a set of brackets (two sets in my case - 4 wheel disk) that allows mounting of Geo Tracker (and the like) calipers and disks. A complete part list from RockAuto (and Amazon) is provided at the end of this article.

 
The first step is ridding the axles of the drums, hardware, and backing plates. I took the opportunity to inspect, replace, and lube all my bearings. The Trackick braket bolts to the axle using the same bolts that held the drum backing plates on (and mounts the spindles on the front).


Once the brackets are mounted and hardware is torqued to spec, the disks slide on. In my case, I did have to open up the lug holes to match my new studs. Your mileage may vary, just be aware that making parts from different vehicles fit isn't always an exact science. After the disks, it time to mount the calipers. Brennan includes mounting bolts and spacers to line everything up accordingly.

The flex hoses are Chevy S10 lines. The front's will reach the stock hard lines, while the rears will require some moddification to the hard lines to make space and accomodate the flex lines.


RockAuto parts list - full disclosure, I found the calipers local for a little cheaper in Canadian dollars
2 x DYNAMIC FRICTION 33147009
2 x DYNAMIC FRICTION 33147008
2 x CENTRIC 90848009 OE Grade
4 x DORMAN H380280

Some M10x1.0mm banjo bolts from Amazon
I went all new, but remanufactured is also an option.

For reference, I used these as vehicles:
1994 Geo Tracker for disks, calipers, and pads.
1998 Chevy s10 for flex lines.

Not putting the brakes on...yet

I mean, I'm working towards putting the brakes on, however there are building blocks to get there. 


I spent the Canada Day long weekend working on the m38. I replaced all the wheel studs (well, all except the one that I was shorted), rebuilt the front hubs with fresh bearings, and ran the new brake lines along the axles.

Next up on the list is the new master cylinder and the front and rear brake lines.
 
The order is in with the remainder of the parts needed. Calipers, pads, rotors, etc. shortly after those are in my grubby little hands the Jeep is going to have brakes. 

To be clear this will mean it has a running engine and [will have] working brakes. My driveway is about 50' long, and I sense I may be taking my first 100' road trip before the end of summer. 
 
Front axle lines installed, the kit from Omix-Ada is a pretty accurate fit

The back lines are much like the front. We'll call it a solid "good enough for this guy" fit.

The new Master Cylider is on the bench, waiting.
