Decide to bite the bullet today and ordered a new set of Brake Discs from James Sherlock for the RS. These are Hakkane Discs, priced at £72.00 each including VAT.

For you guys outside the UK, the only problem is that they are on a service exchange scheme and you will have to pay postage to get them back.

I should get them in a couple of days and will measure the thickness and post a couple of pics.

Although these are the cheapest that I can find, it is still a high cost and I recently changed all the Discs and pads on my Mitsubishi car and the total cost was £134.00, inc. VAT and delivery.

This is an exchange service? So you get BMW carriers and new rotors? This is $72 pound for the pair. Are you replacing your pads as a set to go with the rotors? Once beded in your impressions would be welcome. And the first couple of applications would make an interesting read also.

Each disc is £72 pounds, so I have ordered two front and one rear, also new pads. My existing pads are fine, but I will always replace pads when replacing discs.

Cheers

Now I get the Mitsubishi car quote. What type of pads are you going to run Cintered, impreganted? Chewing gum impregnated pads are find for the first application but tend to be a bit sticky there after. Keith

It's amazing how much variation there is between various rotor suppliers. You've found some that are far more economical that what I typically see. I hope they prove to be good quality spares.

Discs and pads arrived yesterday.

The discs are refurbished BMW carriers with new Hekkane rotors. Thickness measured is 5.045 mm, or 0.198 ins. The current discs on the bike are 3.44 mm and I think the min should be 3.556 or 0.14 ins.

The pads are Ferodo Platinum.

I will get some pics. later today.

Cheers

Bryan

Photo's of the new Discs.









Will get them fitted in the next couple of days.

James Sherlock charge a deposit of £50.00 when you order the new discs and that gets refunded when the old discs are returned.

nice !

I am more than a little jealous. Well done.

Just picked up my new rear disk rotor attached to my new (SH) 16 tooth final drive. The disk looks great and came with a new set of pads. The disc came from Metal Gear and all up cost me $249.

New Discs and Pads fitted today.









Was expecting a difficult job, with tight Allen screws and bolts, but they all came off easily.

Have only done 50 gentle miles so far.

My new EBC 'floating' rear disc arrived today for the outfit, but I won't be fitting it until I change the swing arm and FD with my 'spline running in oil' mod. I've had warped discs before and these floaters claim to eliminate warping..... we'll see.



Looks cool though
Paul.

I've had a set of EBC floating rotors on my 1983 R100RS for a number of years. Excellent bit of kit!

looking good beejay

better post up some pics when you get a chance dave

Wow that looks great I didn't know you could get such a thing for the k's where did you get it from ?
Halo

Motorworks, Halo.

Hi, mine has been for the last 3900 km, no issues so far.
Best regards
JAP

I have one on the rear of the K11 and it is a better brake than standard.

Thanks guys,
That's good feedback; as you would expect the back brake gets more use on an outfit.
Paul.

I've just found this info about the technical details of the 'Square Drive' floating discs.....having watched the video I'm glad I bought one!

Reviving an old post I know but...

Beejay any word on how the disks are holding out?

I also fitted a pair of EBC discs to my restoration bike a couple of weeks back and love them.


These were ordered direct from EBC over the web at about £117 each. There was a packet of new screws in one disc to attach the ABS ring with.

alright for those with the 16V! The 8V are £177 I can't believe the design can be that much different!

They're 'only' £151 from Motorworks.
Paul.

LOL the thing that may persuade me to spend the extra is the positive reports that there are about swapping over to EBC, I have a feeling that the cheap one's from James Sherlock may be only a bit better than the originals, and of course they are not floating disks....

I still have life in my disks so there is no rush at the moment, but be good to have a plan for what to get in the near future...

How much better than the originals does one need?
I've got a few miles on 2 different 85 K's behind me as well as several R's. I've never had any issue with the discs on any of them. As for wear......I think all modern (or many anyway) are designed to wear as do the pads. I first noticed this wear on Mercedes Sprinter Vans. New rotors with every set of pads or at least every other set. I'm guessing that the softer metal in the rotor adds to the braking performance "grip".
I'm sure I'll get a lot of contrary opinion from the group.
Perhaps the "better" brake discs are needed for riders that are severe users?????

The Disks have been fine, with no issues after 2000 miles. Performance seemed better than the old original BMW disks, but their thickness was below spec. and although the bike passed its annual MOT, the tester kept giving an advisory on the annual test.

The K has now been sold, as I had problems with it's weight and wide seat and replaced with an XJ900.

I still look at the forum daily as it's one of the best and doesn't have the 'flame wars' of so many other forums.

I have noticed that on cars the disks can wear out very quickly, one of the guys in work said that they are now considered consumable items, at £80 that's a possibility but when it's twice the price I do wonder.

The original disks on my bike have done 80,000 miles but the front are just below spec so should fail the next MOT. My rear disk is slightly warped, not by much.

I may put a cheap disk on the rear and use EBC on the front. I don't think there is such a thing as having to much braking power! As long as it's used in the right way...

My bike has supposedly only done 64,000 miles and the front discs were 3.5mm thick - 1mm below minimum! I am lucky in that we have no MOT of any sort for bikes here in France, just for cars. I only left the UK and came to live in France for the biking and I'm still here 9 years on.

3.5 mm and flat as well? I am curious when I take mine off and put them on a record player what it's going to sound like. I think it's going to play a tune of hard metal...

It will probably be "Daybreak" by Michael Haggins

TC if you play your disc's on a record player and you hear Queen's "I want to ride my bicycle" your in trouble if not them the disc's are ok

At the moment the rear brake is squeaking like mad. I took the new pads out again yesterday and cleaned the pins up, applied a thin layer of copper grease to them and the back of the pads but to no avail they were ok for the first couple of miles. It's embarrassing!

Thats no good mate, have you taken a rasp to the leading edge (thats the rear edge) a couple of turns with a rasp will take away one possible noise point usually just a 30% angle is enough

leading edge of the pad compound itself? hadn't thought about that tbh, The fronts did take a while to settle in I seem to remember....

yep just a couple of turns to soften the edge on the pad material itself

I think I may just have to give that a go, a job to do on saturday in work i think

we call those little jobs foriegners over here, it seems once upon atime many foriegners were done on OT of a Saturday more than actual work we were there for, but that was then and now, well shhh
