Anyone know if these would suit my ZZR600

Has anyone purchased discs from these guys ?

Are/were they any good ?

Very good, got a set on mine, why risk Chinese cr*p when these are such good value.

Hi

Got them on our ZZR600. Done about 4K~5k so far and are fine, although to be honest they have been very mild miles for the brakes.

All the best

cool beans,

I'll get some ordered next week.

Should i replace pads and fluid while I'm changing rotors ?

Are sintered pads a lot better over standard EBC ?

Read that ^^^.

They warped.

Hi

Fluid is up to you. Depends on the age, but easy enough to bleed some fresh fluid through.

I would put fresh pads on with the disks though. There will be a tendency for the disks to wear to the worn pads, and the cost of new pads is nominal compared to the price of the disks.

All the best

Oooo crap ! I use her for commuting, so will be heavy on brakes for trip to and from work.

I heard that Waver kits are ok, although I though these were more for track days rather than commuting?!

So then the ones from Coventry are OK then Keith? Just seem a good price for the pair.

Hi

I can only go on the ones on our ZZR which are fine, but that is pretty light use (ie, 90% down motorways). I haven't heard of any issues with them at all (except the earlier link) but not sure how many they have sold.

To be honest I wouldn't expect commuting to be that heavy on brakes. Yes plenty of braking but probably few real hard stops from great speed generating loads of heat.

All the best

Keith

Hi

Fair point, but from the given link it I took it the suggestion was they were Chinese (or at least that is what people would read into it).

Not sure if the other user tried returning the disk that warped. A browse around suggests that they will replace them under warranty. What put me off the Black Shadow disks was the terms on the warranty for warping (pretty much that they don't warp, it is the thickness of the disk varying which isn't covered by warranty)

All the best

Once I get my new discs, I was looking at replacing calipers, and wondered, as people say Nissin ones are good, what bike I can also get these from as a straight forward swap without any buggering about !?!?!

Hi

Don't think there are any that are noticeably better that fit without any buggering around.

Various Hondas have some that fit with minimal work (think some GSXRs as well, and even very later ZZR600s). However the mounting bolts are smaller. You need to get some top hat shaped spacers made up (to slightly adjust the offset on some I think).

There are alternative ways to fit them. Either enlarging the mount holes in the caliper (I am not keep on the idea of making the mounts weaker) or some people just put the calipers in place and do the mounting bolts up tight to try and keep them in the right place (really don't like this idea).

All the best

So maybe, I should just stick with originals, but take them off and overhaul them and perhaps switch to braided lines and perhaps Dot 5 fluid ?!

Hi

They are a pain to strip down. If you can get some spacers made up I would be very tempted to use some Honda calipers.

They have a few weak spots. The pistons seize up fairly rapidly. The pistons have a stuffer in the middle which makes the "expanding bolt" type piston removers useless, and the stuffer degrades which will allow the pad to move on the piston. They don't appear to be that rigid a caliper. The have some horrible little screws to hold the anti rattle shim in place.

Braided lines might help if your existing lines are knackered.

If you change the fluid make sure you do not use DOT 5 as it is silicone based. DOT 5.1 is fine though an compatible with DOT 3 and DOT 4.

All the best

Keith

Just called Laguna Motorcycles near me, and asked them about costing for overhaul on brake calipers and fitting braided lines, and they said about 2.5 hours to do that.

I mentioned that the left hand caliper is either binding on the disk, as it pulses when using front brake only.

They said that they can take a look at the bike first on their brake tester unit in the workshop for £17.00, which will identify if its caliper, or warped disks.

Surprised

May just mean that I need caliper overhaul and that disks arent warped. (fingers crossed)

I will probably still go for braided lines, as Paddy, keeps on about its always a good first mod.

(wonder how he is going in court today)

Hi

A sticking caliper can warp a disk but I would think it unlikely that after that freeing the caliper will solve the problem.

I am a bit meh about braided lines. Biggest advantage for most people is that they force people to bleed their brakes thoroughly. Not saying they are useless or worse than rubber covered lines (although they more damaging and easily damaged if they rub on anything), more than they seem to be regarded as a magic fix all.

All the best

I have checked my current lines, and there is no damage or bulges on them, so again, perhaps another "not required" spend.

Things are fixing themselves merely through chat Wink

If I dont need disks, or replacement calipers, then perhaps I will get myself a couple of nice end cans (road legal) of course. or a beer can holder up on the handlebars Laughing

Hi

I would worry a touch more about the down pipes than the cans. Cans are 10 a penny but the down pipes are harder to get for reasonable money.

On ours even with braided lines and a lot of effort bleeding them, and rebuilt m/c the brakes are still pretty spongy.

All the best

Hi Keith,

Luckily, the person who had the bike before already purchased and installed S/S downpipes, so this has already been done. Surprised

Any other good mods to think about ?

Hi

Not that I can think of that would definitely suit it. Sure you could spend money on a higher quality shock and sorted forks, or for touring panniers and heated grips. Depends what you want to use the bike for.

All the best

Ooo heated grips sounds like a good idea.

I use the bike primarily for commuting to and from London (85miles round trip daily) so the grips definately seems like a good idea? Perhaps one of those heated waistcoats, if anyone knows if they actually work well

Hi

In theory keep your core temp up and your body has plenty of heat left to keep you fingers and toes warm (well, at least at UK temps). In practice some people seem to get cold extremities however warm their body is.

We have heated grips on the ZZR and they work OK. Heated gloves are maybe better, but then you need to plug yourself in, and find somewhere to locate the control so you can get at it easily.

With the grips I just wired them up directly to the battery via a relay triggered by the feed for the rear brake light switch. This way no real extra strain on the wiring and they switch off automatically with the ignition. They now just have a switch rather than the control unit (regulator / rectifier went, and that seemed to kill the control unit).

All the best

Keith
