Advice needed: loose brake rotors

[slob]

Hi folks, need a bit of sage advice here. The front brake rotors on my Gixxer 750 are quite loose - they move back and forth about a couple of mils and a wee bit sideways too. There's a TradeMe auction going for what I believe are identical rotors (for about $200) - I'll be confirming this by having a look at them tonight. Do you guys reckon I ought to change them? I estimate that I'll be keeping the bike for up to another year. At the moment I feel like changing the rotors simply because they make an annoying clunk each time I hit a bump (no matter how small) on the road..

Once they get excess movement forward and aft the carrier's holes are starting to elongate,they are toast or close to it...If you have a 96 up GSXR any TL/ GSXR1000 to 2002/Hayabusa or GSXR600 rotor will fit as long as it is a 320mm flat carrier..if you have a pre 96 GSXR i have a close to excellent set of 310mm rotors (fwiw)

200 bucks is bloody cheap for a pair of discs. Even if you don't use them, buy them anyway for when you do.

I've heard of getting discs re-rivited to stop them from doing that, if the brake surface is still good

Those rotors on Trade Me will fit a 96 up GSXR SRAD..of course whenever i see a set of gold centre rotors like the ones being sold,i think of the set i let some GSXR600 racer try before buying... guess he liked them enough to keep them ..i guess the check is still in the mail or he forgot the way back

Yup got a '96 SRAD 750.
Paid the guy a visit last night - turns out the rotors are exactly the same EXCEPT for the thickness: they were 0.5mm thicker (confirmed with a digital caliper)! The min thickness figure stamped on the rotor carriers is greater by the same amount too (4.5mm vs 4mm).

Do you reckon they'd fit?

I'm after a set of 310 diameter disks. any pictures?

They will fit for sure..the thinner version was on the 600 for one..all bolt on though...only other difference is the number of retainers ,10 on the earlier version then going to 8 but again does not affect fitment.

I will get some pic's of the disc's,i'm having a big clean up and sort out so it might be tomorrow ...How about a mint polished GSXR1100M front wheel ?

Its one of those things I hold dear, the ability to safely and quickly stop. Could save your bacon ahe? You really want to risk it? I'd get it sorted no matter what the cost.

i'm trying to get a set of disks to fit a marvic. looking at the picture on trademe mentioned earlier, if the mounting holes are the same, i reckon they should fit. i might have to come around and have a good look at yours.

keep me posted.

The bore in the centre of the carrier is bigger on the 310mm.The PCD of the bolt holes different also,plus the 310mm have a dished carrier,flat on the 320mm.I will get some pics and measurements first thing in the morning to compare to the Marvic.

good stuff. i'll measure up my old disk as well.

i've included a diagram of the pertinent measurements.

Whoops,obviously the newer 320 will have the bigger bore to suit the bigger wheel bearings,not the other way as i posted above.

These should get you started

IVE REPRESSED ROTOR RIVETS B4 AND HAD NO PROBS , EVEN TESTED THEM NUMEROUS TIMES FROM 300 TO 0 , AND THEY HAD MOVEMENT SIDE TO SIDE AND BACK AND FORTH B4 I PRESSED THEM
