As previously mentioned I was having issues with my brakes, after installing larger front (4 door) calipers and rear disks. I only had a 7/8th master cylinder and it was not displacing enough fluid to put pressure on all of the calipers.
After some research I found that the samurai guys have a similar issue with their stock cylinder. Most go the Subaru (1-1/8th or something) route or the Mazda 929 (1" bore) route. I was looking to keep it Suzuki (and pray it is a bolt in solution), and after a few hours on the autoparts websites, decided I would try a 1999-2005 Suzuki Grand Vitara Master Cylinder from the V6 Four door option (1" Bore). I was torn between this or the 1996-199s Sidekick Sport, I do still think either would work. Also there is a huge cost savings here, the one I ordered was only $100.00, while the Subaru and Mazda 929 options are about double that.
So I bit the bullet and made the order. The Master came in and initially it did not look good. It only had 2 ports this is the worst case scenario that can happen but it is really not a big deal. I'm not sure what to tell you guys here, I cant remember if I ordered the ABS one or the non-abs one, but either will work.
Here is a comparison, Grand Vitara on the left and two 7/8 2 door kick masters on the right.
I took come measurements and every thing looked good except for the push rod length. It was clear i would have to shorten my stock length by about a 1/4".
Highly accurate ruler
I work by my self and knew from other posts it is very unwise to pull the push rod from the booster in a sidekick as it will not go back in. There are tabs that hold it in place and once removed it will not go back in. I put pressure on the brake pedal to extend the push rod.
And was relived to see that I could thread the end of the rod in a 1/4" to solve the issue. RESULTS MAY VARY (I don't know??)
So I got some Vice grips to stop the pin from turning and a 7mm socket and cranked the tip in.

Now all you have to do is bolt in bleed and come up with a way to tee the lines for the front brakes. The low level sensor even fit right in to the 1996 stock harness, no modification necessary !
I am going to use the stock splitter for the front brakes that is located on the Passenger Side of the Frame. I previously modified this anyways so I only have a single line running to the rear disks. Again, this may not be the case on your rig but there are other ways to Tee a brake line. Affordable easy solution.
The same night I made up some little mounts for the rear shock. Partially inspired by BRD HNTR's build and Talonxracer's ideas to mount them perpendicular to the axle. I wanted to keep them out of the way of rocks but didn't have tubing wide enough for the shock to fit into. These are designed by inventory, but I'm happy with them. Other than reversing into a rock they should be good.

Flex, not all the way. I didn't want to get to crazy in the shop.
To be honest the front is not flexing like I had hoped. I am thinking the springs will break in as I begin to put miles on it.
Just the Skids, Front Diff and Tire Carrier to go.
