Thanks to this forum my 03 X's vibration in the 75 to 78 + MPH range is now gone. This forum provided the source of the problem and I have fixed it. I rotated wheels/tires front to back and torqued lugs to 150 ft lbs. - much improved!! Next I rotated the rear axle (tipped front end up) to square up the driveshaft/u-joint/axle input shaft centerlines. It took a 1/4 inch shim at the rear of the riser block. I did not re-balance the Driveshaft. Drive line is as smooth as silk on up to 82 MPH. (Didn't take it any higher). Before this work the vibration was quite harsh above 75 MPH. I am satisfied.

I have improved the brakes to a point that they are great. Changed to PFC Carbon Metallic pads all around and installed Stainless Steel brakes lines at the front and the one flex line between the frame and the rear axle. Solid pedal with minimum travel and stops quickly.

Many thanks to forum members, Richard V-10 03 White X.

Can I ask where you got the stainless steel brake lines and how much they cost? Also did you do the work yourself? I want to know how much and how hard it would be to put them in. I don't like the mushy brake pedal feel.

Good luck with the new X.

Be carefull with stainless braided brake lines, they like to pop quite often. personally, i would never, ever use them. Richard, is your X lifted?

The lines I have are from egrbrakes.com. $189. for 3. I did the work myself and found it to be very easy. The lines you use must be DOT approved. My X is not lifted.

Jared,
Could you share a little more info about the problems you've seen? I've been considering replacing the factory lines with stainless braided in order to firm up the brake pedal some. Aren't braided lines just a rubber line (similar to factory) with a braided jacket? Wouldn't that be stronger? I thought that braided lines were used on race cars?
Is one manufacturer better than others? Or are braided lines bad in general?
Thanks!

Yes I'm quite curious about this too. I never heard of them popping, but that might just because I'm ignorant.

Also, why's it 3 pieces?

The set of lines I have are for the two front wheels and one piece from the frame to rear axle. The short lines to each rear caliper are not changed as they are so short and do not contribute much to the mushy pedal and also most of the braking is done by the front brakes. These lines have an extruded inner teflon core, kevlar cover and then Stainless Steel braid on the outside. EGRBrakes.com and Russell Division of Edelbrock. You can get more info from their web sites.[quote]

I dont have them personally, BUT over on a popular bronco site we several people who have popped them. Basically, the braiding does not allow the rubber to swell in severe braking conditions. So, without flex it has to come out somewhere which results in a popped brake line.
They do provide a firmer brake pedal because they dont swell. Not everyones have popped, just some.

And race cars, rock crawlers and show cars typically dont weigh 10,000lbs and carry your family around. You or your wife jam the pedal real good and fluid must swell in a rubber tube or escape somehow. Its up to you. My brake pedal is firm, i dont need bling on my brake lines and id rather have a safety net. my 02.

But, if i had a harley or a T bucket, or a cobra mustang, etc.. I would get them in a heartbeat.

Jared,

I want to investigate the "popping" of Stainless Steel lines. Please give site/forum addresses so I can follow-up and see if their conditions are like mine.

Thanks, Richard from Knoxville,Tn.
