Land Rover disco one weird brake situation, any help?

[b jeepin]

Hey I searched the net and was surprised to see I couldn't turn up any info on the scenario I have currently. I'm working with a 95 discovery 1, 3.9, manual trans. Truck is lifted with ome kit and allot of extra bumpers racks/ weight. Lately Ive been towing a handful of heavy trailers for few hundred miles at a time. On my way back from last trip I heard some squeezing, which just before I got home sounded of metal on metal contact. My assumption was pads shot, noise was from the rear. I purchased new pads and was going to install, I pulled apart to find left rear outer pad was loose in caliper. The pad life was ok but pad shifted down into the circular hub section of rotor digging a nice groove. It appears the pad has play between the caliper itself both sides when it slides in. Pins and retainer springs look fine, I see no signs of metal damage on caliper itself really, right side is snug and working fine. I'm curious how this happened and if replacement of the caliper is best solution or do I have an underlying issue?

I can get pic tomorrow if needed but to dark now! Any help? Suggestions? Anyone had this issue?

Have you taken it apart to look at it? Perhaps the pins are sheared/rotten? Maybe they weren't installed correctly to begin with?

Its apart, pins are ok, pads were installed fine, no trouble for last 5+ years. I'm going to get a few pictures, that will hopefully help in the next hour or so. A new caliper should correct my problem, but I'm concerned about how this happens. Don't want to have an underlying cause and repetitive issues.

Looks like the tab that rides in the retainer clips in the caliper broke off? What do the pads look like off the vehicle? Seems like a pretty simple fix. New pads.

Yup. I've seen that on my 94. Thought that would be the issue before reading too much.

There gets to be enough wear in the caliper that you cant avoid it.

Replace with a new or reclaimed / unworn caliper and you'll be happy.

My 90 RRC had this problem with both the back calipers. I tried using a welder to build the material back up and then grind it flush, but had a hard time getting the contours exactly right. The pads would get crooked and jam so in the end I bought a set of calipers from a junkyard that didn't have any wear. I would go this route if you have access to rovers getting parted out. much cheaper than new calipers and much less of a pita than what I tried.

Thanks guys! General lee that is a great wear picture as well. I will order up new caliper. I just didn't know if this was a long term wear issue or if I overloaded with my towing. I have 140k on her now, so mileage wear doesnt seem weird. On the other hand I had about 9000 lbs I hauled so I wasn't sure, just didn't want to have ongoing issue that ruined new parts.

Glad to help. Def had me stumped for a while. Something I have been thinking about after doing this and going through and rebuilding all the calipers on her was instead of replacing with the original calipers that come on the RRC and d1 was if the nicer, simpler floating calipers of a d2 would fit on the axles. all it would take is for the mounting holes to be the same spacing and adapting the brake line to the new caliper. Really easy and much better design just as long as the mounting holes are the same

Update. I ordered new calipers for the rear, no one had stock locally, so I decided to order cheap ones online through rock auto. They had a close out deal on nugeon? Brand. Had aluminum Pistons, and price was right! Add more to my dilemma....visually parts looked great but I jumped into install to find the mounting holes were undersized! So I measured and check overall fittment looked good, so I ended up deciding to re drill the mounts to the appropriate diameter. To date performance is good just wanted to give others a heads up on new parts that will need machined to fit!
Thanks again for the help!

The earlier trucks used smaller diameter bolts. I've seen this wear issue on alot of trucks due to the spring plates being installed upside down. If they are installed correct then you should have zero movement. There are also alot of crappy pads out there where the backing plate is not quite OE size and that leads to wear issues along with harmonic problems. Glad you fixed it.
