Problem with GSXR front brakes. - Page 4 - SV650.org

yup, penny dropped

i personally use k4/5 600/750 forks as they have taller mountings with k6 callipers and 320 discs and it fits like a glove. the reason for this is that the 320 discs are readily available cheaply from blackshadow.

Ok so I spent some time on the lathe and have turned up some spacers. The front wheel does seem to spin more freely than before now so hopefully problem solved.

Just about to test ride so I will let evryone know the result.

I was under the impression that the sv1000 discs where 310mm but mabye I was wrong lol

SV1000 are 310mm.

Clean the copper slip out. Use red rubber grease.
You should be able to push pistons back by hand, if you can then seals are OK for now.

Personally I think master cyl is problem.

Test it, then crack nipple off and retest. If it is master cyl cause then that will free it off.

Well the spacers seem to have worked so hopefully that's case closed. I made a spacer out of some stainless on the lathe.

Thanks for all you help guys will post some pics soon.

double check the pads on the discs to make sure that they are landing on the disc face properly.

and yc is correct the sv discs are 310. my mistake. but i suspect that you have actually got a gsxr 1000 k1-2 front wheel or similar. is there any way you could actually measure the discs?

Aye but are your pads overhanging the disc now? You don't want this.

21-04-12, 07:11 PM

The pads look like they are on the disk face ok, I suppose the real test is to look at pad wear in a few hundred miles.

I got the wheel of davepreston who said it was a sv1k wheel, but arnt the k1-k2 gsxr wheels the same as the sv1k?

I suppose this will tell me what the wheel actually is. I can mesure them on Monday

The Wheels are from a K1/K2 GSXR1000 to my knowledge
But maybe wrong on this

don't matter about the wheels as all the diamond spokes fit radial forks up to k8 (cant remember the exact cut off) with different spindles but if preston sent him a front wheel from a 1000 k1-2 with discs to match then the discs will be 320mm.
