Rear brakes, skreeeeeeach, metal on metal

Recently, I hit my rear brake and heard the horrible skreeeeeeaaaaach, just like metal on metal.

So, I ordered EBC pads which arrived here pretty quickly. While I waited for the new rear breaks to arrive, I just used the front brakes.

Tonight, I figured out how easy it was to pull the rear pads, took me a long time though. When I dropped the first rear pad, I was shocked to see bare metal! I cussed myself out for not checking them when I did the 12K (they were replaced around 4K). When I pulled the second pad down and saw about half the lining still there, I thought I had a REAL problem with only one pad waring!

I turned the first pad over, and, viola! half a pad sitting there.

I was wrong on all counts.

Even thought the skreeeeaaaching sounded like metal on metal it wasn't. And, of course, when I looked at the first pad, I was lookin at the piston, back side, instead of the side with brake padding.

Tomorrow morning, yank panels off to get at the speaker connections again. The rear speakers are distorting, again.

But, after thats fixed, off for a nice ride, in the 50s F and sunshine, to Phoenix for the weekend.

Have FUN
Bob

If you're only getting 8K out of a set of rear pads, something is amiss. Either you just needed to clean them and all would've been well, or you're riding around with your foot resting on the lever. Rear pads should be good for at least 20-30K, maybe more.

Of course, there's nothing that says you can't replace pads just cuz you want to.

I was going through rear pads pretty fast myself. Started at new pads with every other tire change and it reached the point that 7 or 8k was about it. After noticing the rotor was starting to blue I took a closer look and discovered the caliper pistons were sticking. Replaced the caliper and got a major improvement, I still haven't worn out the last pads. Curious to see how long they last now.

If you have problems with distorting rear speakers it might be the connections in the back of the radio...

A good way to see is to get the radio sounding distorted and make a fist and give the BMW Rondel on the stingray a pretty good wallop.. If your distortion goes away... your working on the wrong end..

I had the same peoblem with the rear speakers sounding "fuzzy" and cutting out. It turned out to be the wire harness up on the stingray (the one with the round connector). The harness is about 8" longer than the other two and the factory just stuffed it up under the stingray where it chaffed through the tape covering and into one of the speaker wires.

As others have said, it is the stingray connectors. I chased that problem round and round the bike, convinced it was to do with the radio itself or the intercom system. If I took the stingray off and left it to one side, connected as normal, it would behave perfectly. No amount of tapping around the radio would provoke it. Put it all back and the problem would crop up again. Eventually, I stripped it all back, cleaned the plugs and made sure they were fully engaged (they can be stiff). All back together and no problem to date.

Hope that helps. Andy in Gloucester, England

Update

Update.

I installent the EBC pads, pumped the rear brake a few times to get the new pads seated and off I went to Phoenix. On my way back to tucson, 4 days later, not a single skreach, let alone a peep.

Wonder if I put EBC pads in the front if I can make a wind chime with the 6 leftover BMW pads?

I could get a blown rear bearing from someone and use that as the clanger in the middle of the brake pads?

My LT has had the rear brakes squealing ever since I rode it away from Euro Cycles of Tamps Bay. It was given its 12,000 mi. service before I rode it home so I knew it wasn`t worn pads. I asked the service manager of Ft. Myers BMW about the problem at down town bike night. This my neighborhood. He told me that squealing rear brakes was common place with LT`s. His suggestion was to stand on them at 30 mph. and that may glaze them over and eliminate the noise. This sounded like a quick fix to me. Since my bike is in the shop in Tampa where I bought it, I will suggest the EBC pads as a solution. Hopefully EBC doesn`t stand for anything in particular and is the product name. Thanks Bob.

Just a thought ... That squeel can also be a sign that the rear disc is not floating like it should.

It'll take a few hundred to thousand miles before the new pads will start to squeel as bad , but if that disc is frozen it will happen again.

yah... you're right!
it happened to my husband's car... he replaced the old EBC pads with a new one thinking that it was a bad pad. after driving thousand miles, the squeeling starts again. so we had it check, it was a frozen disc.

Oooooops.

Maybe I posted too soon. I was riding in town today and heard a squeal. Hope I was riding past a barbeque place.
