Hi Everyone,
New to the forum here but had my 1995 XJ600S for about 9 months now. I was wondering if anyone knows what the service limit is for the rear brake disc, all I can find is "it should be stamped on the disc" which it isn't. It's down to 3.7mm now and that seems a little thin to me.
Sorry if this has been covered somewhere on the forum, search isn't working for me, keeps generating errors.

Thanks for the information, it's something I may look into in future but for now I'd rather keep the bike stock. I've got all the proper tools, impact driver, torque wrench, blow-torch, etc to get the old disc off OK so I'm fairly confident I can get it changed, just not sure if I actually need to or not. I do a lot of miles (12K so far in the 9 months I've had it, and I do over-use the rear brake a bit) so I'm concerned that it might go from MOT pass to actual failure before the next MOT.

I think the wording on the MoT is such that the disc has to be literally paper thin for them to have a watertight case of failing the bike for it. Being under the rec min thickness is not enough to guarantee a fail. However, excessive grooving is a fail.
That's not a very good answer is it :/
Perhaps it'd be a good idea to keep an eye out for a cheap disc, and do it as and when you need to get the spanners out anyway? It's good that you've got all the tools, I would advise that you consider these bolts will be tricky, and just go straight in with the big boys' tools - a good few days doused in plusgas and get the blowtorch out straight away. Like I said on mine 5/6 snapped off flush with the casting, so it would have taken a lot of work to rescue that wheel. I think it was a combination of ancient threadlocker combined with corrosion on the backs of the bolts. So the blowtorch will probably be your best friend.

Just thought now I've sorted it out I'd post to this thread with the results.
I grabbed a new disc from sandy bike spares on Ebay, although when I called them up and tried to negotiate based on the fact if I bought directly from them it would save them the Ebay and paypal fees and they were a bit rude about it so I won't be buying from them again.
It turns out 3.7mm was MUCH too thin for the disc, when I took it off, it said min-thickness 4.5mm on a bit that was on the inside where it couldn't be seen. Getting the disc off proved very easy in the end, I sprayed WD40 onto the bolt heads every couple of hours all day beforehand and when the time come they just came right out no trouble at all. Had the new one ( and new pads ) fitted in under half and hour and it's all running nicely now, seems to be wearing more evenly too.

I sell pvc banners via a website, and the WHOLE idea of it is that when you place an order the entire thing is automated and I don't have to employ someone to talk to you and take payment details over the phone which then have to be submitted to the card company to get my money. Paypal sorts the whole thing and the very first I know about the deal is that I have the money in my account and there is a job ready to put through the automated process. The paypal fee is small in comparison with the cost of the administration necessary. The moment you step out of the virtual world and become a real person I would have to start charging you more, not less. I would try hard not to appear rude, but I would be very unimpressed if you asked me to charge you less for having to do more work. |

I can see your point for a custom item like a banner where doing it over the phone would involve quite a bit of work for you for data entry, design, etc. but in this case they already have the shop and the people on the phones anyway, entering the order would take all of maybe 30 seconds, and allow them to avoid in the region of £6-7 in assorted fees.

Ive had good service from Sandy Bikes so will be using them again when I need to.
I got my discs from a company in Coventry. Cant remember who, but they are in the recommendations section.

Have you been to their "shop"? It's basically just a warehouse in the middle of nowhere (well, Bedfordshire, actually), with a couple of guys who do everything. So I can see why they might prefer an automated way of doing things. Having said that, they were very helpful when I went back to them with a problem with an exhaust. |

Wemoto seem to be able to deal through web sites/directly on line/on the phone or in person only problem with calling in is they are always on the phone but no delivery charge. handy as they are only a couple of miles down the road.
