Brake Disc Bolts

[The Male Whale]

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!

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!

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.

[Falcon 269]

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?

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.

Understandable, but should be no problem to a good machanic.
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

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.

I re listed the rear ones and got 15 quid for them

[Kosmic Kartman]

I'm gonna polish the ones I removed on my wire wheel and stick em on fleebay.

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!!!!
