Brake rotors?

[slofox]

Despite a half hour of trawling posts via search engine and google, I am no closer to answering my own query. Lots of the posts are old and ergo may be out of date.

The Vixen (K8 GSX-R600) probably needs new rotors on the front - got the dreaded pulse pulse pulse thingy.

Since I am now a pore ole grampa wiv only half a hincome, I need replacements that are a compromise between quality and price. No junk please but don't need to be the best in the world IYKWIM.

Any current suggestions?

Thanx.

I'll start you off...

How about Braking STX rotors
US$465 shipped from Motomummy here (https://www.motomummy.com/store/home.php?cat=475)

or EBC contoured rotors
US$460 shipped from ebay here ( http://www.ebay.com/itm/08-10-Suzuki-GSXR600-K8-K9-EBC-Front-Contoured-Brake-Rotors-MD3100XC-2-/310411097743?hash=item4845f1768f&item=310411097743&pt=Motorcycles_Parts_Accessories&vxp=mtr)

Thanks - good places to start.

Factory part number if you want to go that way is 59210-37H01
This number matches the 08/09 600 and 750, and I believe the 09-10 600 also.

EBC ones are around 250gms lighter :D

Gotta ask, why is it pulsing ? I wouldn't expect a K8 to need discs yet. Have the discs been off recently ? Grit on the mounting faces ?
New rubber fitted ? Bent on the tyre machine ? Carrier bent from a knock ?
As another tight old bastard, I'd put a DTI on them on the wheel and see what's what before spending hard won pension funds....
If it's the carrier tweaked, it's often possible to get them straight again with careful work.

Thinking along the same lines. Had a pulse on the GSX650F K8 front but since new pads fitted, gone. Pads cheaper than rotor.

Yeah, that's what I was going to suggest. There's been posts on the VFR forum about pulsing brakes caused by wonky pads. If you're going to fit new disks, you'd need new pads anyway, so why not check that out first?

Right, well that's a good idea, innit. Got the 48k service next week anyway so will have a look. Just me usual jumping to contusions. Thanks all.

They won't kit a K8 600

[imdying]

Fuck that gook shit... if the OEM discs have managed a thrash happy 48,000km then get another set of them.

Give them a good scrubbing with some light sandpaper and rebed that pads. Check them for thickness too... if they're at minimum throw them away regardless of whether you get them to stop pulsing or not.

I noticed that too...

Well on my bike being really old you can see if the rotors are warped by just turning the wheel id thought they should be okay if bike

Not that old . on car you can reverse back with brake on not sure that works on bike , but maybe just take pads out give clean.

Clean calibers these good video on youtube for this just need some soapy water and tooth brush .

[mossy1200]

Pulse is most likely a stuck floater pin or excess pin wear.

[Corse1]

Pulse can be build uP of pad material on the rotors. A drill with a rotor hone attachment can fix that have to remove rotors though to do the job and also if they are semi floating buttons they could be full of crap. Spray bottle with hot soapy water while spinning the buttons does wonders. Allows them to semi float again.

[F5 Dave]

If braking from a reasonable speed with purpose & you can feel it tapping your fingers at the lever they're bent. Dial gauge will tell you same thing. In a pinch a piece of wire taped to the forkleg, but depending on amount of float can be tricky, more-so on Brembos or racing stuff.

They'll warp in a week if pistons are dragging & 48k is certainly a reasonable innings as Imdying states.

[G4L4XY]

Well this thread is interesting.

After getting a new chain + sprockets fitted I was told the rear rotor "has had a hard life" and will need replacing very soon. Though after reading this thread and seeing the "pulsing" of the brakes...I've noticed when I need to be a bit hard on the front brakes there seems to be some "pulsing" going on.

[slofox]

Turns out the left hand rotor is warped. RH is OK.

I could get just one but something tells me I ought to do the pair - is that something talking sense or bullshit?

These items seem expensive to buy. Like EBC's are around $US200 EACH on Ebay.

I see Metalgear brand is available locally. Any good?

[G4L4XY]

And because you're replacing the rotors that would mean you need new pads too right?

[SVboy]

I recommend MOTOMUMMY in the states-just got some EBCs and Carbon Loraine pads for my k6. A bit cheaper than e-bay, 50$us shipping. Have dealt with them a lot-prompt with never a hassle. {and yes-do both with new pads.}-sorry

[scumdog]

Not essential if your pads aren't too badly worn

But I recommend replacing them anyway...

[F5 Dave]

A sensible clean up of the pads on flat sand paper would suffice, but if any wear that has taken it from parallel or flat & you're not doing the discs any favours, or the braking efficiency. As the disc suppliers don't know what condition your pads are they insist on new pads which makes sense. This indemnifies them from muppets using pads on the crock, overheated from binding piston & contaminated from a leaking fork seal then coming back saying the discs are at fault.

For the purists, consider on race bikes the wheels are continuously swapped & no one changes the pads at each swap. They do however do little (but hard) mileage have consumables kept in good condition.

The gixxer.com forums are great for that sort of thing.

Yeah - I posted on there too. Not that much response though.

On the SRAD forum I've had a hell of a lot of help, and ridiculously cheap parts (compared to NZ prices). I'm surprised you haven't had offers for cheap parts there.

Prices I was quoted were about the same as here...or more.

[SVboy]

I replyed to you on the gixxer forum. If you get new, you will be hard pressed to beat the EBC prices on MOTOMUMMY and s/h oem rotors on e-bay are pretty reasonable, even with shipping.

I got Wave ones on my GSF650N .. Got them from SweetStreet in Hastings ( http://www.sweetstreet.co.nz/ They were half the price of bringing them in from England ($400 the pair all up - 800 pounds plus p&p from Pomlandia) and got them overnite ...

They are also silent (the standard ones had a swishing sound when not braking .. and a louder sound when braking)

I'd recommend trying Sweetstreet.

Not necessarily but worth checking - I put on the new rotors without changing the pads and just gave it a few trips to work themselves in ... I got a few bright bands on the rotors where the pads were touching the rotors - which became a solid metal strip after a few trips ... as the pads and rotors working themselves in ... (took me a while as I touch the brakes maybe three or four time between work and home ... unless traffic forces me to brake ...)

[Premature Accelerato]

I purchased of "Sportsbikenz" (based in the Manawatu) through Trademe. Bought a set of front rotors for my GSXR 750 track bike and have not had any trouble whatsoever. Reasonably priced
