Every vehicle I've ever worked on has had a brake hardware kit available that includes caliper slides, etc. I've checked all my online sources and they don't carry one. Nor does Zeckhausen (although I admittedly haven't called yet).
Since I apparently have a pair of sticking calipers (the inside pads on my fronts are pretty much gone, outsides are new) I'm guessing the last guy didn't use new caliper slides...
Anyway, does anyone have a source, or do you all just order the individual parts based on what you see in RealOEM?
And yes, it is that PM time of year - brake pads, t-stat, coolant flush, brake fluid flush, fuel filter, belts....
i wouldn't use new slides... i would take the old ones scotch brite them... get off all the built up road grim and old grease... then use a polishing wheel and put a nice smooth finish on them... problem solved...
i've never replaced them either, just cleaned and greased.

x2. Never done BMW or M5 brakes myself, but the only time I've replaced hardware is on drum brakes. Well...actually on calipers I've needed to replace OEM metal brake pad "novibrate" shims that had rusted, but that's all.
On calipers the guide pins just need to be cleaned and relubed w/ non-washaway brake lube. If they aren't fused to the caliper your uneven pad wear most likely points to internal caliper issues. And if they are fused...ouch.

If you want your oil pan repaired (see http://www.m5board.com/vbulletin/e39...rain-plug.html) instead of buying a new one or attempting the repair yourself PM me and we'll work something out. Thinking $60 profit is worth it. You pay all shipping of course. At the moment I have four remaining Timesert inserts looking for homes. If the demand is there I'll keep doing them. If not the tool goes on eBay minus one insert.

I have replaced them. The dealer has them and it didn't make any difference on my car. I though I may have had a hanging caliper as well but it wasn't....
ok, I'll just clean them, but if I get a sticky caliper again it will be the last time I help any of you Oh wait, you've been helping me lately. Nevermind!
I've always replaced them just because they are cheap. And yes, TMcNasti-name, the hardware kit is typically associated with drums, but on discs you are supposed to replace the slides (without lube, so they don't get gunked up) otherwise you get a sticking caliper. I'm really surprised both of mine are stuck.
The best part is that I broke the passenger one free last night and now I have a nasty shimmy. I don't have much pad left on the inside, so no bedding until I get new pads...

Uh oh! I hope you didn't grease the caliper slide pins ("guide screws" in BMW lingo) on any factory BMW brakes. The slide pins are specifically NOT supposed to be greased, since that will cause the rubber bushings in the calipers to swell, causing the caliper to stick. This results in rapid outboard pad wear. See:
BMW calipers are DIFFERENT than calipers found on many other cars, where the slide pins are located inside a steel tube, covered with thick "slide pin grease" and protected with rubber boots. Those slide pins look like this:
2001 540i 6-Speed
StopTech 4-wheel big brake upgrade (ST-60 front/ST22 rear)
M5 3.15 Limited Slip Differential M5 Front Swaybar
Dinan Stage 3 Suspension
Dinan Front Strut Tower Brace
Rogue Octane Short Shifter & Transmission Mounts
European Dash Conversion CDV Deleted (of course!)

Ah good to know. I just AZZ-U-MEd that all calipers ran with the sealed/lubed guide pin technology pictured. Figures BMW does it differently. Good way to increase caliper sales I guess. I'm quite surprised they'd go with something different then what's in the above pic. The pic above technology works perfectly. No wonder Doug is having problems! Do BMW exposed/unlubed pins get jammed up regularly? I'd imagine they would, but please tell me if I'm wrong.
