Hi There

I have a 1999 LC100 with 156 k miles on it.

Live in an area where we have no salt for de icing.

But thinking of safety shall the stock rubber brake lines be changed ?

What other areas to check ?

Brakes are normal and no fluid loss.
 
Think I have heard of a hose failure or two on here. Had them fail on my Suburban.
Went to stainless steel hose on my LC.
Wouldn't hurt to change them, and its a good opportunity to flush brake fluid.
 
Its a good idea to replace them, over time the rubber hoses tend to expand while applying pressure to them decreasing brake performance.
Go to a steel braided line
 
156K miles may or may not be much depending on use, but 20 years is getting up there. Environment they've been in, if keep clean, etc all makes a difference.

If not replacing they should at minimum be inspected biannual at that age. This is best done with someone pumping/pressing/hold down hard on brake pedal.

What brand of stainless steel brake lines to go with for the 1999 LC 100 ?
Stoptech ?
 
Just replaced the stock brake lines with stainless steel “ Stop Tech” bought from Rock auto.com

The stock rubber ones were still OK but mechanic told me when they fail sometimes they do from the inner area.

With 20 years of age it was overdue and the safest thing to do.

Was this on your '99? What were the part numbers for the Stop techs from Rock Auto? Their website is hella bad.
 
Slee should be able to sort you out if Rockauto won't do. Possibly more expensive, but you know it'll just work. And come with the right hoses for your configuration.

When purchased my LC, the rear rubber hoses were leaking. Called the dealer and they were dirt cheap! Don't go aftermarket if available, I actually seem to remember at that time nobody made the rear hoses, or at least they were nowhere to be found in stock.

Hi Ayune

Yes for my 99.
It was the only Stop Tech stainless steel when you go by year model. My e mail is having issues. Will try to retrieve part # and post them
 
Part # from Rock auto attached.

Nice... Just make sure the stainless braided hoses have some sort of protective cover (vinyl?). You dont want dirt to be worked into the braiding. Also you still have to be very careful handling them during service too. They can still fail... Ive had a 5yr old Goodridge SS brake line rupture (different vehicle) out of the blue, under heavy braking.

I still like to use SS lines, but will make sure they are protected and never physically stressed, twisted, kinked, etc.
 
So, purely for my education, what's the upside to paying more for stainless steel braided hoses you can't see and have to treat with kid gloves, instead of replacing the old hoses with OEM hoses, which have been observed to last for decades through rough treatment or simply being ignored?
 
SS brake line do not flex like OEM or traditional flex lines. This yields a rock hard brake pedal feel. When I installed a set in The Unicorn after refresh caliper, rotors and pads. Braking was scary, in how fast and hard they grab, with just very lite pressure on the pedal. Took some getting use to.
 
Looking to change out the original brake hoses on my 2000. I'm under the impression that it requires 6 hoses (pretty sure my truck has the traction control and antilock system, or whatever it is that means 6 hoses are required instead of 4).

Sorry if this is a dumb question, but I've combed so many threads my head is spinning.

Slee is out of hose kits. So is Cruiser Outfitters, who also carries the Slee kits....as well as every other aftermarket custom 4x4 shop that was a source at one time or another.

I've found some of the Stoptech hoses, but the kits they have for a 2000 only have 4 hoses, not 6.

Are there any other options for sourcing stainless braided hoses? Could I just have a local place build me some custom hoses to replace the 2 that are lacking from the stoptech kit, and buy that kit for the 4 hoses it contains? And if so, does anyone happen to known what fittings those hoses would need, and/or what length they are, so that I could have them made without having to tear the originals off the truck so I can get them matched? I think I read somewhere that those hoses are 15.5" end to end (these would be the bumper to body lines if I'm not mistaken? I thought I read this earlier somewhere but now I can't find the thread.)

Thanks in advance.
 
So I just installed the Slee kit on my 2000LC this past weekend. You should have 6 hoses on your truck. I dont know exact lengths, but I think I saw it mentioned with pictures in the Slee SS brake line thread. You definitely could get the Stoptech hoses which I believe cover the connections to the calipers and then have the missing ones that connect the rear axle to the body made at a local shop. I was going to pull all of mine and bring them to the local Parker Hydraulic shop to get them all made if I didn't get a kit.

The two that are missing from the Stoptech kit are female connections on both ends which the body/axle hard lines screw into. From memory the rear center lower one looked about the same as stock and the rear center upper one looked like 2" longer than stock.
 
@jamesIV SS vs Rubber... I really don't think it makes much of a difference (though I run SS lines on 4 of my cars). Most OE high performance brake lines are rubber as well.

Since everyone is out of stock, I'd suggest getting the (4) OE brake lines (caliper ones). For the two (rear axle to frame) brake lines, one is short and one is long but I believe they have the same ends. Use the new OE longer one on the short side (lower one), then have a hydraulic hose shop make up a new longer one for the "longer/upper" side. Make sense?
