Rear Brake Disc; How quickly have you destroyed yours?

minivin · Post by **minivin** » Sat Jan 07, 2006 7:42 pm

Well, about 26k miles into the bikes life I looked at the original rear pads and thought "ah, a little low, I'll replace them now!"

In went some Ferodo pads, on my 2002 EVO ABS bike and it all went pear shaped.

at 34k miles I am now in the position of having to replace the rear disc (have a new one sat here that cost me £125 from Sherlocks) and go back to BMW pads as the Ferodo's are on the plates nearly

Having talked to my local BMW dealers, they say that the EVO II has the intelligence to know how long, at what speed, the brakes can be held "on" until the pads get too warm, the system then reduces the pressure and spreads the load to the other brake circuit to keep all good.

They then went on to say that as the EVO II would think that BMW pads were fitted, it would then apply the wrong pressure and cook the pads at a moderate heat, while eating the disc.

what does others think as I can see the sense since it's an intelligent system, BMW are well-known for over-complicating things (like the rear tail light, stop lamp and stop light switch monitoring FFS!!!)

Ribbed for your early Demise, could be an advert for Durex......

Shinny new disc, which I wouldn't need if the above disc wasn't sat at 3.9mm thickness instead of the required MoT thickness of 4.5mm as stamped on the sucker

Mine went the same way - can't remember the mileage, but it went through 1 MOT with it wafer thin for which I got a 'advisory' or summit then I bunged on the spare from Julians old bike just before the following one. Mine hasn't got the evo brakes either so it can't be that.

You're not alone

BTW - where is the speedo pickup on your bike? Mine is under that blanking plate in your diff

I think the ABS sensor may be used to provide the speedo as well, scary electrics

it's the only two wheel position/speed sensors on the whole bike

How would they do it for non ABS bikes? Having said that, non abs bikes always did have a different rear diff (sans the ABS hole). Still, just another difference to note on the later bikes eh! Mine is ABS but still has the speedo pickup off the castelated ring inside the diff

I think like as you say, different Diff with the castelated ring pick-up instead, may keep an eye out for one as when I plan to rebuild it in many years time the ABS will come off and the electrics will be made minimalistic

Hi Minivin

I'm amazed you didn't ask on here for a rear disc,125 quid!!!!

Having measured a disc there is very little meat in them between new and on the limit, something like 0.65mm IIRC, so decided that new was best on such an application

However the catalytic converter is rattling badly again only after 12k miles so I may be looking on here for a Remus Y piece soon

You DONT want a Remus Y piece I think. I think the Remus Y is universally agreed to be a disaster - Also - my Remus collector system goes 2->2 and I don't know whether their Y does too - means you'd need another set of (Remus) silencers too.

He he, been out of the loop too long

was looking at a Remus on Ebay, two into one so the standard silencer pack is used, however that is a pipe dream <boom boom!> as got plenty of other things to sort out before titavating the R11S

Had a Remus Y piece fitted to my 1998 R1100S last August connecting up to the standard silencers. I've put a couple of thousand miles on the bike since and must say I'm perfectly happy with it. Improved sound however not too offensive by any means. Regards Bob

Funny how people always have converse opinions on things

think it'll be the end of the summer by the time I get around to fitting some form of Y piece

Okay as A former Remus Y-piece chap myself, why do you think it's so bad Jason ? The only reason mine is not on now is I put a full Tunes 2-2 setup on it ( Thanks again Andrew

)

I found the only problem with the Remus Y-piece was the lugs didn't line up especially well. That never bothered me I just siliconed them into the rubber rings when fitting it, though I believe many have sawn them off completely with no ill effects.

I found it a well made, good fitting ( apart from the lugs

) usefull bit of kit. It gave a good boost in the mid range and added a nice rorty thud to the exhaust as well.

Anyway, I'll be interested to hear what's so bad about it. . . .

Hope everyone is well and had a Cool Yule by the way.

Well TBH I've never ridden the Remus with the Y but.... Everyone else I've spoke to that has ridden both (and whose opinion I value, like Gromits and Lloyds for example) have panned the Remus Y for the 'hole in the middle' and lack of torque compared both to the Remus balance box version (which I have and which I'm told is a much more grunty option) and also to other aftermarket systems such as the Laser etc.

So whilst I admit that "universally' agreed to be not good" is not strictly true, it should have read "everyone I've ever spoken too who has ridden a variety of aftermarket systems including the Y piece Remus seems agreed that it's not that good and is all noise and no action"

So how do you think it compares to the 'tunes?
