Cheapo Disks

[Pykie]

Hi,

anyone had expirience of either of these two different cheapo rear disks? Or suggest something else?

I'd like the stainless one from James Sherlock to turn out to be good, or am I asking too much for 65-odd quid?

Not tried those. I've bought the cast iron fronts and they're fine... till it rains. At that price I reckon they're worth a punt, especially on the back. New discs are a stupid price, they're only a piece of steel with holes in FFS. I can get new vented ones for the car for a fraction of the price. Someone somewhere is just taking the piss.

I've got loads from ebay also - as long as they're thick enough and flat then they've been fine too.

Steptoe sells discs as well as many other consumables for the GS. Check out his website here. His are listed at £70 but at least you have the comfort of knowing where they came from should any problems arise. You'll go a long way to find better.

Have a close look at those discs, and then have a look at mine in the picture.
Do you see any small cut outs in the inner part of the disc inbetween the mounting holes as you do in mine, as per the BMW original discs ??

No. Because those on ebay are made to a price, including the quality of the metal used.

Mine maybe £5 more expensive, but you're getting double the value.

I've got a set of three Stainless sleet ones from Sherlocks on my 1150. No problems at all, nice quality kit.

I've had cast iron discs (& the recommended organic pads) on a couple Ducatis and to be honest they weren't as good as stainless steel.

At £60-70 you are doing pretty well but also watch the shipping for bumping it up. £70 ones are still far cheaper than the orig!

The cast iron ones seem like a good idea until you park outside in and sort of wet weather. Overnight they can seize to the discs.... I user to keep a mallet and allen key in the pannier just in case.... PIA!

Also a bit susso in heavy rain due to the lack of holes...

Thats the pass marks of two sets of quality controls.

Sorry, but on what basis? Used properly SG cast is a material of choice for discs

You would say that when you don't live and ride in the damp, wet UK.

Wet and Warm in Summer 7 months, Dry as a nuns for 5 months in Autumn spring and winter and winter is about 2 months but sill warm 20C whilst sun is up, and a mile above sea level so no floods like Brisbane, so Zero Salt or kark so NIL Corrosion, without any care, no fixing stone chips it doesnt matter But yes lazy so I use ferritic stainless discs, semi stainless for rust

Thanks for your help everyone.

I decided to take a punt on a disk from steptoe in the end. Must be that silver-tongued sales pitch at work.

I wouldnt be at all suprised if the James Sherlock ones are fine as well though.

The disk is to replace an iron disk, I'll not fit another of those sodding things again. In the winter it sprays iron oxide crap and shite all over the interior of the caliper and the spokes and wheel rim, which then sets quite hard and corrodes the sodding rim (if you don't clean the bike religiously, which I dont). Not practical in the winter i reckon.

Your choice maybe but not mine.

On my Multistrada (a mix of all weather year round commuting / Sunday fundays / Touring), standard discs with sintered HH pads was much better than Ferodo Axistech cast iron ones with their recommended street spec organic pads. When I complained they sold me a set of their sport/track sintered pads which they claim were compatible with Iron discs, but they still didn't work satisfactorily.

They were truly appaling in the rain. Lots of pad float and zero braking, then coming on very suddenly after 2-3 seconds when the water got cleared off the disc. In the dry they didn't have as much ultimate power or feel as my oe discs and sintered pads.

Being a sucker I tried a set of Brembo fully floating Iron discs on my ST4s and they were a no better, still not offering much by way of feel or power in the dry. Can't say much about the wet performance as that bike never went out in the rain.

Previous experience years ago with a Brembo CI disk on my GPZ500 was good and after a couple of pad changes the pair of PFM CI discs on my VTR1000 were very good, so I'm not saying that all Iron discs are rubbish, just that they're very variable and I shan't be gambling another £600 on whether I get a good set next time.
