My DII (2001) had a sticky brake caliper about a month ago, so in the shop it went (LR dealer). This past weekend it began to have intermittant troubles with the brakes. Sometimes it was fine, sometimes we could feel drag, the brakes were heating up, but never consistently. So, it got hauled back up there for further servicing.

The explanation we got today was that the brakes had "reset" themselves and were responding as if we had SLS, which we do not have. The shop said they "reset" them again. On the long ride home I felt nothing odd, but then again, it's an intermittant problem.

Here's the exact written explanation, with some punctuation corrections from me, because I couldn't stand it :-) :

"Performed road test. Unable to verify or duplicate customer's concern. Performed ABS system diagnosis. Found mulitple faults in system. Found ABS had converted to SLS set up. Cleared all fault codes and reconfigured ABS system. Performed system bleed with test book."

Maybe this is right, but do I have to worry it could "convert" to an errant set up again???? Does any of this make sense? Given that the other things we're having problems with were also not fixed or otherwise attended to properly (I've just written the service manager) I'm losing confidence! Big time :-(

Leslie,

The topic list indicates you replied to this note, but I don't see any reply. If you did, would you mind reposting your reply? Thanks!

I don't see anything from Les.

How do your rotors look?

Karen,

Resetting back from non-SLS to SLS is:

1. Unlikely to be permanently fixed by a SLABS reprogram (though this is the official first test). Usually a new SLABS or a new main ECU is needed to fix.

2. A possible cause of the problem but not a likely one.

Did you get ABS TC and HDC lights? If not then the SLS/non-SLS thing would not be the issue (unless the SLABS was so bad it was not throwing codes). It is possible that there was a problem with the SLABs causing the valve block to lock up but I would call it highly unlikely (I have not seen it).

Based on your description (which is classic sticking caliper) I would say that it is a sticking caliper (or E-brake). I would wait until you feel the issue and there are a couple of things you can try.

First: either when code or hot does it pull under braking to one side or the other?

Second: does it pull not under braking? (usually pulls the other way)

Three: Both cold and hot to all wheels spin free?

Forth: the easy thing to do is to look and see if one of the rotors is "blueing" which would indicate the caliper at fault.

Fifth: abnormal pad wear if it has been going on a while

A sticky caliper is not to be messed with, if you have any indication the fault was not cured by the dealer take it back. Their explanation is plausible, just really unlikely. Odds are they could not find the caliper and to CYA they did the ABS diag.

Craig,

I saw on the topics list that Leslie had left a reply to this note, but upon clicking on the note, even after refreshing, logging out and in, etc., I never saw a note from him, either. Maybe just a board glitch. As for the rotors, I don't know how they look, we'll have to check.

Ron, thanks for the info. Seems to me the SLABS was replaced on a recall shortly after we bought the Disco. We got no warning lights at all, only the sensations I described. No pulling at all. A month ago we smelled brake pad smell as we were driving in snowy conditions on the highway. Lousy time for a break down! Swung immediately into a Goodyear service center and they put it on the lift and DX'd a sticky caliper. I called LR and had it towed in. They replaced the caliper and off we went until we began to have these new intermittant problems.

There seemed to be no consistency in the brakes heating this time around. It never was both fronts or both rears for instance. The right front seemed mildly warmer than the rest, that was the only thing relatively constant. Nothing ever got as hot as when the original rear caliper seemed to be heating up. We initially heard a squealing from the rear, possibly the left rear where the caliper was replaced. Only once did we hear that. Once or twice I felt the brake pedal depressed too much upon starting the truck. Nothing ever seemed to happen often enough to diagnose. We drove it very little as we waited for the dealer to work us in.

I dunno, someone (at the dealer's) is really going to have to explain to me how this system could suddenly decide after 2.5 years that I have SLS. Given how poorly the rest of our issues were handled yesterday, this feels like more un-kosher info. I'm working on getting some answers, and better treatment, from them.

"how this system could suddenly decide after 2.5 years that I have SLS."

I can tell you that it just happens sometimes. One of the more common SLABS faults, in fact. Saw it a lot after the recall replacement of the SLABS.

Without seeing the truck I don't think I can offer anymore help. The random brakes heating up is very, very odd. You just have to check it systematically.

Ron, thanks again for the thoughts. You are saying that AFTER the "bad" SLABS were replaced you saw this "reverting" scenario happen? If this is the case, what would keep it from happening again and again? Feel free to treat this as a rhetorical question, and thanks again for your help.

And away it goes! Back up to the dealer's again, for the third time in four weeks. If and when this ever gets resolved, I'll report back.

In some cases it was just the initial programming with the recall was bad and a reprogram fixed it. In others the "new" slabs was faulty and needed to be replaced again. Not a high number of failures but enough that we saw a few.

Karen,

I know how you feel. Mine's been at the dealer now for 3.5 weeks! They replaced the hub and sensor, MAF, gave me a new tail light, but they are stuck on the remote control. Wrong voltages at the testbook, which just says 'error', they ripped out all the panels inside including the roof panels. beginning to think I'll never get the thing back.

But they have kindly lent me a brand new D2, which had 46 miles on it. Now its up near 500!

Good luck,

Dean

Ugly bit of business, isn't it Dean? A new DII, eh? I was "lucky" enough to score a local rental of an Envoy. So far, I've driven it.....home.

They gave me a Yukon first, but then they decided they'ed rather not pay the $35/day rental, and it was better to give me the first few miles on a new disco!

Fine with me:-)

Wow. Sorry to hear about that Dean. Although, you could do worse than take advantage of the headliner and panels being out to run some wiring...

At least it sounds like you are still in warranty...

And no, in answer to your question in another thread, I still haven't done the damned hydraulics (there's a hose adapter part which I never received from a vendor, now they say they are re-shipping). I have, however, done a bunch of other stuff, some of it involving the vehicle... And I have a electromechanical CDL control on order :-). When I figure out how to post pictures inline... I need to go read the archives on how to do this... hmm, just noticed the attachment button -- lemme try now anyway...

OK, so here's the bumper

here's the loadspace with the really heavy carpet replaced with some lightweight ply

here's the shoreline which charges my batteries at night...

here's a better view of the jack mount, although it does not show the safety cables which I hadn't got round to fitting at the time of the photo

and here's the loadspace again





P.S. or, on the other hand, here's none of the above since I just found out there's a 320x240 limit... I already got done editing the images from 2 megapixels down to 500x400, I guess I have to start over...

Hmph. Now they're small enough, but I figured I'd put it on the original thread rather than hijack this one... I'm thinking of the one about lug stud thread sizes. But I see that's archived now. So, OK, I'm going to post in the non-tech area anyway otherwise someone will complain that I'm going off topic... ho hum.

More satisfied Disco II owners with trucks in the dealership service bay for weeks on end?

Just wait til your warranty expires and the #5 cylinder slips a sleeve, then the real fun begins.

With a truck this expensive to repair, I won't be caught without an extended warranty, Sandy.
