Re: Brake Disc Bolts - old son - 27-01-14
Today is maybe not to good. I fitted a Brembo disc to the rear and that is OK.
I fitted Armstrong Wavy discs to the front and they seem to have issues. They are OK with light pressure but as you apply pressure it seems as though the pads and being thrown around the callipers. There is a bit of a rattle and then almost a graunching noise as I apply more pressure. I can also hear a sort of whining from the discs and this noise gets louder as I apply more pressure.
It could be they need time to bed in. If that is not the cause then does anybody have any ideas what the issue might be?
Re: Brake Disc Bolts - unfazed - 27-01-14
If only Brembo made front discs for the Fazer :'(
May just be the bedding in process. My front EBC discs made some weird noises for the first 100 miles, still make weird noises, but not as bad as the first 100 miles.
The rear Brembo is as good if not better than the original and no weird noises
Did you fit the discs yourself and was the wheel surface where the disc is attached cleand off because if it was not the discs may not be on straight.
Re: Brake Disc Bolts - old son - 27-01-14
I did clean the surface where the disc is attached but I think I will try spinning the wheel against a fixed point to see if there is any run out. I doubt if there is because it would vibrate all of the time, not just under hard braking.

What pads did you use?

I have seen the Armstrong discs warped from new.....
Also, pads need to bed properly and this evidenced when there is a good marking of the discs fromn the pads.

Thanks, I have done about 60 miles so far. The chirping noise I get when braking reasonably hard is quite loud. Not very impressed so far!
Re: Brake Disc Bolts - Falcon 269 - 31-01-14
Hi Sean
I also have the Armstrong wavey discs with EBC/HH pads and they are quite noisy in operation. Mine have been like this for nearly 3 years. This might be a feature of slotted wavey discs regardless of make ... I don't know but maybe others here can comment?
Provided you're not getting any pulsing at the lever, it's a reasonable bet that the new discs are true.
Cheers!
Mike
Re: Brake Disc Bolts - old son - 31-01-14
Hi Mike, no pulsing but it feels like the pads are dragging on the discs under heavier braking. I think it is settling down though. I must admit I preferred the standard discs.
Re: Brake Disc Bolts - Falcon 269 - 01-02-14
Agreed, Sean. Apart from being a bit lighter and looking more trick, I can't detect any advantage in day-to-day use and compared with the brakes on my 99 R1, I don't think there's any point in going with Armstrong wavy discs over standard.
Live and learn, eh?
Re: Brake Disc Bolts - nick crisp - 01-02-14
I always wondered about pad wear on some of these wavy discs. Do they not cause more wear because the pad material is running over those shaped edges of the disc? I notice standard Kawasaki wavy discs aren't scalloped particularly deeply in from the edge and wonder if this is to avoid such issues. But I've never seen criticism of them for this reason, and so was assuming they were ok. Thinking of getting a set myself at some point, hence the interest.

If things don't improve you can buy mine!!!!
I got wavy discs on my ZX 10R and they are fantastic.

Many are not aware of left hand drill bits, which the the job much easier.
Job Done....money well spent and no hassle.....even picked it up and dropped it back off at my house
Re: Brake Disc Bolts - lloydy-taff - 06-02-14
I've replaced front and rear discs with armstrong wavy's, sintered pads and hel braided lines and all bolt's to stainless .after an initial bedding in period everything has settled down nicely ..

I upgraded my brakes to 3 x Hel lines front and back, sintered pads and Brembo master cylinder....not tested it yet due to the shite weather we're getting here

Please note for the rear disc (FZS1000 01-05) you'll still need some of these (below) as the bolts listed above don't fit the rear disc:

You'll have 6 bolts left over from the link that Luke posted... But buying the two sets combined still works out cheaper than buying a complete set for front and rear discs exclusively for the FZS1000.
Re: Brake Disc Bolts - devilsyam - 16-02-14
I re listed the rear ones and got 15 quid for them
Re: Brake Disc Bolts - Kosmic Kartman - 16-02-14
I'm gonna polish the ones I removed on my wire wheel and stick em on fleebay.
Re: Brake Disc Bolts - Timabusa - 21-02-14
Had a similar problem fitted new brake discs black shadow and new EBC HH pads then the bike developed really bad vibration problems when braking turns out after stripping the calipers off outside the hotel in the IOM two pistons we're sticking obviously the dust seals have failed so they at off to Powerhouse in Sheffield how do a caliper refurb service hopefully this will cure the problem!!!!
