|
|
I dare say cheap as i want them to be decent quality :p but as i mentioned on my other threads the discs on the new er6f bike are rather worn and could do with being replaced.
So Wheres a good place to get affordable disc brakes?
Theres loads of cheap ones on Ali Express... but... you know... china...
If there is any decent sets though on Ali, let me know
But if you know anywhere to get decent ones... let me know that too

Each to their own, depends what you're ordering.
Only issue I had with them was a rear brake switch that didn't work as advertised (generic one it seems that was, I think, too short to function properly). ____________________ The do it all, T̶h̶e̶ ̶b̶r̶o̶k̶e̶n̶ ̶o̶n̶e̶,̶ ̶T̶h̶e̶ ̶b̶i̶g̶ ̶l̶u̶m̶p̶,̶ ̶C̶h̶o̶n̶g̶ ̶N̶o̶o̶d̶l̶e̶ |

I only order genuine parts and my brake cleaner from wemoto, their aftermarket stuff is terrible.. |

Here's a question and this thread seems a suitable one...
Is there any issue using an aftermarket disc one side of the wheel and OEM on the other?
Asking for a friend who has a tendancy to smash a disc lock into his and bend the disc. ____________________ The above post is most likely nonsensical.

If wavey isn't an issue for you, try https://www.blackshadow-uk.co.uk
Don't be put off by the retro website. Phone them up and talk to them. Very knowledgeable, decent people. Disks are made in Wales, too. ____________________

Slightly different materials may offer different coefficients of friction, different thickness' could invite a different levels of bite, different wear rates could alter performance across axle. ____________________ The mistresses: 2000 Honda CBR600f, 2000 Honda VTR1000

And wemoto are the ones I use most frequently. I also use fowlers but usually for Honda parts if David Silver is out of stock.
I also normally go with OEM brake disks but use EBC pads (replace pads and disks at the same time) as they are better than the stock er6 pads. I have an EBC disk on the back at the moment though. Works absolutely fine but gets to look rusty very quickly if it gets wet and I leave the bike sitting for more than overnight if that bothers you.
I don't fancy used ones - they're likely taken off for a reason such as a bike that's been in a smash and I don't expect they'll have been checked for warping in most cases. Might just have been removed to fit more stylish ones but I reckon that's the minority.
Wee tip regarding the er6 - if it's a 2009-2011 model or older and the fork tops are flush with the yoke lifting them 5-10mm makes a big difference to the steering feel. I did this a few weeks back after owning the bike for over 3 years and really wish I'd done it sooner. Steers more lightly and more predictably now and is much easier to adjust mid bend. Stability is no worse. Its a common change thats often recommended. Might benefit the later model's too but I don't know if the geometry is different. The new ninja 650 comes this way as standard but is it course substancially different. Also grease the stick coils next time you remove them as they tend to corrode and get stuck. |

They are the company that don't believe in, and therefore don't warranty against their discs warping:
https://blackshadow-uk.co.uk/Fitting.html
Quote: | Many riders confuse rotor warping, or warped rotors, with a condition called DTV (disc thickness variation). DTV occurs when a vehicle brakes are serviced and the brake rotor has runout in excess of 0.08mm . This runout causes the pads to contact the rotor when the vehicle is being driven "off brake" and after 3-4000 miles( Sometimes Much less), a thin spot develops on the rotor. The rotor runout itself does not actually cause a vibration. It is the effect of the thickness variation of the brake disc or brake rotor under braking that causes pulsation. Even small thickness variations such as 0.012mm or 0.0005" will exhibit itself as pulsation. A warped rotor is a very rare occurrence and in many years in business, we have seen no genuine cases of warped brake rotors.
The general guideline is that if the vibration happens immediately after install, there is a quite severe runout problem that needs looking into. Brake discs or rotors should be mounted on flat smooth rust and dirt free hub flanges without the use of coppaslip which includes small particles which have the same effect as dirt. Remember that even a small particle of 0.001" under the rotor surface can cause a deviation of 0.005 at the pad contact point.
Semi floating and fully floating discs are designed to have some "Free" movement to allow for heat expansion of the rotor.
An Example Your wheel turns once every 1.9mtrs thats 842 turns per mile or
842104 turns per 1000 miles. If there is any runout Irregularity, on every turn of the wheel, a minute amount of material is taken off the high spot as the caliper does not retract the pistons fully each time the brakes are applied. In Time this will wear a thin spot altering the Parallel flatness which then CANNOT be remedied, only by stripping and Re-machining the Rotor
Even a particle of DUST can measure .0005"
If the vibration happens after 3-4000 miles and sometimes Much less, this is a clear indication that DTV has occurred which is not a warranty condition. The only solution for this is to remove the brake rotor, have it re-machined if possible, or replace it with a new rotor.
Every case of "Warped Discs" reported to us has been caused by NOT checking the Run-out when fitting. |
