Vit/GV/XL7 Owners - want rear disc brakes?

I spoke with Spidertrax, the makers of the original rear disc conversion for the Samurai, about an idea I had.

I did some research and it may be very possible to do a disc conversion on the GV. I recommended using Suzuki Swift GTi rear calipers. These are smaller than front GV calipers and would provide the necessary proportioning. Also, they have a parking brake which front GV calipers would not. BTW - GTi calipers can be had at Autozone for $90 each.

For rotors, I recommended using ones from the front of a Suzuki Samurai. They are cheap and plentyful, fit the 5on5.5" bolt pattern of the GV and are the right size for the Swift caliper.

The price of the conversion kit would be approximately $200, give or take, and would require you to purchase caliper, rotors, brake hoses and fluid.

Here's the catch, they would need to have 10 pre-paid orders for them to do the R&D and produce them. Do we have 10 owners here or elsewhere that would like to be part of making it happen?

This may also lead to the development of a conversion kit for the Sidekick rear. Good news!

The list starts here: 1. "Yankee" Tim Walters

Who's next?

Re: Vit/GV/XL7 Owners - want rear disc brakes?

Hey Tim, can you say "wrenchophobisa"? Gonna be a tough sell to get my wife to allow me to modify her GV! I'm workin on it!

On a side(kick) note, have you seen the "cross drilled" rotors on e-bay? Is it worth running these, instead of normal rotors?

Thx
Bob

Re: Vit/GV/XL7 Owners - want rear disc brakes?

They are pricy, but worth in IMHO. Big tires reduce the effectiveness of the stock brakes. Drilled up front and discs in the rear should really inprove a Kick with big heavy 32" swampers

Re: Vit/GV/XL7 Owners - want rear disc brakes?

My Vitara/kick eats rear brake shoes in the mud I have been looking into a conversion. The local SJ specialist does a kit for Samurais, he thinks that his Sammi rear disc conversion would kit the Vit if the caliper mount centre hole was machined smaller the only problem would be that I would have to get a parking brake cable made up. Have you thought about this? I like the idea of staying all Suzuki the kit I am looking at uses Rover calipers, probably not very common in the US. As usual the UK price is much higher than in the US. Any idea how much the kit would weigh then I can get some idea of the cost of airfreight.

Re: Vit/GV/XL7 Owners - want rear disc brakes?

From what I measured, the Kick(old Vit) bearing cup has a larger bolt pattern than the Samurai. The GV (new Vits) have an even larger bearing cup than the Kick. But the mount can be machined to fit.

The idea of using GTi calipers is mainly to stay Suzuki. But it also has a parking brake that will be easy to connect to the GV. And they are much smaller than the front GV calipers (which are HUGH in Suzuki terms), so it will provide better proportioning.

As I see it, the kit will be some aluminum caliper mounts and some bolts. I can't see the whole package weighing more than 5 lbs. The buy would need to track down some rotors, calipers and such.

Rear discs on the xl-7 would be nice. Same drum as the GV and more weight. But would this be a differnt kit do to the size of the rear in the xl-7 is larger?

Re: Vit/GV/XL7 Owners - want rear disc brakes?

The bearing cup is the same on the GV and XL7. From what I can tell, the GV uses the XL7 shaft, but it's tapered down to the smaller 26 spline Sidekick diff. So it should be the same.

If you measure yours, I'll measure mine and we can compare. Eww...that sounded really gay. [img]images/graemlins/blush.gif[/img]

Re: Vit/GV/XL7 Owners - want rear disc brakes?

WE DO HAVE IT !!! Price is $99.00. It is a very simple kit and it uses Samurai calipers. We found the Swift calipers to be insufficient - they do not provide sufficient braking power for larger tires and vehicles. The kit will not only fit the Sidekick but the Grand Vitara as well. You must provide the Samurai calipers and there is no provision for the e-brake. [img]images/graemlins/laugh.gif[/img] We also have a similar kit that fits the Samurai and uses Samurai calipers. It is also $99.00 - you supply the calipers - no provision for e-brake. For e-brake applications, we use the Subaru calipers on Samurai's. Both of these items are currently available and in stock - pictures will be on our web page soon...

Re: Vit/GV/XL7 Owners - want rear disc brakes?

No shiit. The Sammy caliper won't be good for the GV, as most will want the ebrake and you can't fit an 410 center drum on it. [img]images/graemlins/crazy.gif[/img] But, can you make them it with the Subee calipers?
