Regular branded discs (Galfer, Braking, etc) go for about £300 a pair. I’ve seen some no-name ones on eBay before, but they looked dire and lacking in quality, but last week I came across these no-namers from Hong Kong and for £130, I thought it was worth taking the risk! So they’re here now and they look/feel great. I can’t wait to get them fitted. I can’t see any obvious difference between these and the branded ones. We’ll have to see what performance is like.
My current discs are 2.5yrs old, of reasonably hard use, so I can notch this one up as a service item
Can’t fit them yet, no front-stand here and the bike’s fitted with full-wets so can’t be ridden anywhere! I’m praying for rain!
Mate, I would be carefull with those, they dont mention what metal was used and I’ve seen quite a few warped ones. I hope they are the real deal I could use a set.
I thought the whole think about wavey disks was that Galfer had the pattent on them so there can’t be any other ‘names’ that make them. Think the problem here is that you are only going to get copies made in the far east that are low quality. They might look good but as is said the Metal is not the same quality. Could be wrong, hope so for your sake. As the saying goes, you get what you pay for.
It comes in different grades, the few I’ve seen were only on for a couple of hundred miles before warping, as the metal used was low grade.
They might be alright and you’ve probably got a bargin, but I’d take it easy on them until I was confident, alot of the cheaper discs I imagine are made for the cosmetic look rather than the hard braking you’d expect around a track or on the M25;).
If you bed them in properly they should be OK, don’t know about bikes but it’s probably similar to cars, warm them up gently then cool them down and keep doing that warm up/cool down until you’re really puting a lot of heat into them (not burning them) then allow them to cool fully afterwards. It’s a bit like annealing, I do it with my discs and it does seem to make a difference. Put new pads in at the same time.Most discs warp because Mr Plonker is tearing down the M1 at 100mph and realises he’s hungry so jams on the brakes at the next off ramp and keeps them applied waiting for the traffic lights to change, so transferring all the heat from the pad into one small area of the disc. Almost guaranteed to warp or put a slight irregularity into a disc. They also warp when they get too thin to cope with the heat, the disc has to dissipate the heat and if it’s too thin it can’t do that.
Unless they’re really not the right material at all and then you’re fo*ked from the start ;)
Hi Jay what i would do is make sure the edges are deburred, and all mating faces are proper clean. I think they wil be ok once bed in, i might change up to Brembo discs soon, bored again :w00t:
Brembo SBK discs? Awesome bits of kit. I had a pair once, but they wouldn’t fit the K5
All edges are deburred, so things are looking up. They’re not fitted yet as the garage said my titanium bolts are messed up and they need some time to sort them out. More cost, as ever
