I've just been talking to Bob (RT) who says that the sintered pads which were supplied by Metalgear with his "new"disk are making a grinding noise and are chewing the disk.
I was understanding that you didn't use sintered pads with Stainless disks but the link to Braketech (which i'm not going to put in because it fills the post with hyperlinks)
says that it's fine.

He's pulled the pads out now so i offered him some spare Motobins ""2280 FDB 108 Ferodo pads 81 on"". Are these even ones that are good for use with s/steel disks.

Can't wait for them to get there by post so he's going down to the "local".

Any one up for running a Brakes 101 tutorial.

I have used sintered metal pads once.  Never again it cost me a set of new iron discs and the pads.
I don't believe that anybody needs metal pads even for the most spirited riding on the road. If you do really need the braking that they give time after time then please tell me before we go for a ride and you can go in the lead.

It's up to the buyer to decide what to use but in my experience sintered pads are a prize waste of money.

Brakes are like tyres the better they are the more they cost and the less miles you get.
Sintered pads will make your brakes better in that they don't tend to fade during heavy periods of intense braking but that isn't the sort of riding I have ever done on the road and even most of the high power sports bikes don't ever get into that  realm when on the road.
One of the things that really gives me the shits with metal pads is that they are filthy things to clean up the mess they leave.

I agree Rick, I use standard pads in the car as well, sick of replacing rotors with pads.

I don't know there probably would be some marking on the package or a part number and go to fredos web site, they should have some sort of listing.

I think you're okay. Theye're a sintered pad but (from Motorworks):


Ferodo FDB108ST front caliper brake pad set pre 09/88 | BRA54725A

Fits K75, K75S, K75C, K75RT, K100, K100RS, K100RT, K100LT
Sintered compound suitable for stainless discs. These have a backing plate width of 55.5 mm.
These are supplied in caliper sets i.e. bikes with two discs at the front will require quantity two.


Oddly, I've got the opposite problem. I have cast discs but the Brembo 07BB1418 pads in there don't give anywhere near enough bite. It's not the calipers (overhauled with new seals and pistons) and it's not the lines (all stainless) and it's not the pressure (lever goes solid within a few mm of travel). I'm going to try EBCs next time.

All the Ferodos at Motobins is organic pads......Ferodo organic pads for road use have a P after the number, sintered have ST after the number.

I'm using EBC HH sintered pads front and rear on my R1150RT with Braking 'wave' discs, and EBC HH sintered pads front but non-sintered EBC pads rear on my K1200GT with factory discs. The RT is a high-mileage bike at 135,000+ miles. I removed the RT's original factory discs and will put them on an upcoming project bike. They have many miles to go and many rivers to cross still, both front and rear. The EBC pads stop extremely well, they don't 'dust' the wheels overly much and the discs are looking shiny and new with no extra wear due to using HH sintered.

All late-model BMWs (except for the G650GS) come with a varying level of sinter in their OEM sintered brake pads, from Brembo, Tokico & etc. The K100RS in my shed in OZ has EBC HH sintered front with Suzuki brake discs and a set of Motobins cheapies out back. I had the excellent Dunlopad sintered up front prior. I think the K100RS didn't need sintered but it's what I had and they stop well. I am not willing to blame every brand of sintered pad for 'eating' non-iron brake discs, though there are some that show the tendency. It's not my general experience at the workshop or with personal use. But folk here have heaps of their own experience.

Perhaps I know why my experience varies from others! It's all that heavy rain whilst riding here in the Pacific North West US. It washes away the grit, grime and dust...

I was under the impression that you can use sintered pads just fine with stainless discs but you shouldn't use them with iron discs as they will just eat them away, is this wrong? Sintered pads also seem to corrode a lot more when left next to a disc in the rain, which is much more pronounced with iron discs - mine still have pits from it.

For the record my K100RS has Ferodo Platinum pads in it along with recon iron discs and doesn't really stop, I can't recommend it. I have been told by a fellow with a K100RT that Brembo pads are the way to go but they are poo-pooed above so maybe it's all down to personal taste? I have also used EBCs in several bikes and think they're fine for road use but again many people think they're awful, recommending Carbone Lorraine or Goldfren instead. For what it's worth even organic EBCs are slightly sintered, they have bits of what looks like copper in them but they don't seem to eat discs.

I had a bad experience with Goldfren - the rear caliper spat out the entire friction lining from one pad. I was turning right off the A470 into Dolgellau in North Wales when it did the dirty just as I was crossing a patch of gravel. The bike slowed violently but didn't quite stop; a big handful of revs and a lot of clutch slip and I managed to clear the carriageway before the next lorry arrived. As I got onto the bridge the backend freed itself up, so I assumed I'd got a piece of gravel in the caliper. A week or so later I saw a light scoring start to appear on the disc and it was then I found (or rather, didn't find) the missing pad. No squeals in between time. No more Goldfren for me.

Snod: I'm not dissing Brembo pads. In fact, I'm rather puzzled because I used the same setup on two of my Guzzis (they use the same P08 calipers gripping cast iron discs) and the braking action on them is really good. I've even mounted a master cylinder from a Suzuki Bandit GSF600 (which runs four-pot Tokicos) on LFB but that's had very little effect on the problem. As it happens, I also have a Bandit 600 and that front brake setup, while not up to racing standards, will put you on your backside without a problem. So it's not the amount of fluid being moved either.

Years ago I always just used Brembo.  The main reason being that if I bought from our local Brembo distributor (who is also a well known Ducati workshop)  I could get a choice of 4 different compounds for the same K100 caliper (also used by many Dukes at the time).  From memory I'd use the soft on the rear and one of the intermediate compounds on the front.  The price was good and I'd get good wear out of them too.

Now I'm using primarily DP non-sintered, good bite, they don't dirty the wheels and seemingly quite are well lasting.  My experiment with Ferodo platinum on the sidecar just gave me pads that wore out quickly. EBC are readily available here but they don't impress me that much.

I don't know Goldfren at all and don't buy just on price, I'd rather something I know I can trust.  DP will do me for now.
