Oh nice man.

My pedal on the mounty now sinks to the floor Iz, what did you do to combat this?

Also, will i need a proportioning valve on my truck if i bypass the abs lines?

Mine sank to the floor too initially but after test driving it, you dont really need to sink the pedal to the floor to lock all the tires. So be careful with braking. You might need to bleed the lines more too.

As for the proportioning valve, yes you need it if it will need it mostly if its going to see much road. But even if its a trail rig, proportioning how much pressure goes to the back does help a little in sticky situations because if the back locks out before the front, it will of course start sliding off the path you want it to go on (important on descents).

the master cylinder could be the problem...you need one out of a f 350 to push those 2 piston calipers...if i remember correctly, izwack used the chevy one ton conversion on his ex which means only a single piston caliper.....yep just looked its on page one along with his sneaky political smile...

 

[IZwack]

Ah thats true Mud Bug 94. I did indeed use the Chevy 1-ton outers including the calipers.

 

[Mud Bug 94]

do you think this is the problem? on a side note im curious as to why hes runnin dually hubs on the front...

 

[IZwack]

I dunno if this is the problem but if the dual piston calipers has more displacement than the single piston ones I'm using, then yes potentially the problem is in that the master cylinder just doesnt have enough volume for the dual piston calipers. The only way to tell is to actually drive the rig on the street -- start off slow at like 10 mph and see how the brakes behave. If it does fine then kick it up to like 20 mph.

Another reason as to why the brakes might go to the floor is the amount of flexible brake hose used.

How did you mount your sliders?

How did you mount your sliders?

Sliders were welded onto angle iron ("L" looking steel) and the angle iron was welded onto the chassis. Then 45-degree gussets were welded on top to brace it to the chassis.

 

[Burns]

OK thought the were welded. What did you do near the gas lines? I want mine weld on but im worried when i get to the drivers side because of gas lines.

I was very worried too but (at least on the 2nd gen) those lines are held on and arranged by a plastic bracket thing (kind of like the guides people use to separate spark plug wires) sitting on the inside of the frame rail. I did try to minimize the heat by welding about 3 inches or so per "leg" (there are 4 "legs" per side connecting the slider to the chassis) and then doing the other "leg" on the other side, then doing another "leg" on the other side and basically kept moving around until all the welds were comlpete. After each weld run, I also used my hands to feel how hot the chassis was getting a few inches from the recent welds. I also took 15 minute breaks every now and moved on to other things on the truck to give the chassis some time to cool down.

Pics, besides the ones in the Rausch Creek thread?

Wow, those 37s dwarf the 36s too!!

 

[IZwack]

I dont have any other pics but here's a drawing of the overal design.

Note that the frame rail kind of starts angling up kind of near the front of the gas tank so not all of the "legs" are the same angle.

The actual 2"x3" slider piece is angled kind of at 45* to allow it to slide better off of rocks.

Again, here is the pic from the Rausch Creek run showing the four "legs" that connect the slider piece to the chassis:

They look great, and from those pics and that vid from the weekend, they seem to have worked.

Thanks! I think they worked but I wasnt really sure 'cauz I was inside the thing when it was on the verge of rolling over .. with my foot on the brake as hard as possible.

And I blame the almost-rolled-over mess entirely on the busted u-joint because the front-left wheel just would not climb and had to be pushed by the rear tires which then turned the entire vehicle from the line I had originally chosen.. so a few seconds later, the right rear was completely off the line and the whole thing was about to tip.

I'm pretty sure your sliders never really scraped on much because of how damn high they are, haha.

And it's OK, it the whole situation made for some great pics and a nice story. Plus I had the honor of pulling you to safety. :

 

[FROADER]

So no scratches on the pass side slider? Was it touching that rock in this pic?

 

[IZwack]

I'll look tomorrow if the sliders have scratches.. after I go wash the damn dirt off. Did I mention I hate mud? But none the less, God still allows mud to exist -- for some strange reason.

 

[FROADER]

I hate it too! that's the sole reason I don't believe...: I just washed mine yesterday.

If I had a dollar for everytime you made your own trail because of some mud, id be a rich man.

I wish I could of seen your face when we got lost in that construction site in whiterock.
