RVF400 Caliper Options

[wogstaa]

Hi guys,

I just serviced my bike and gave the calipers a good clean. Looks like I need to rebuild both calipers as the pistons aren't moving out at the same pace. Master cylinder probably needs a rebuild too...

I couldn't find a definitive list of bikes that have calipers to fit the RVF400.

I was thinking of upgrading to the SP1 calipers but they're proving hard to find in Australia at the moment. Which other bikes shared the same calipers? I couldn't find definitive answers but it looks like the CBR600rr and F4 did.

I just want to double check before I buy anything off ebay, I'll likely try to find a set including the master cylinder.


Short Version: Which other bikes have better caliper/master cylinders that'll bolt on to the RVF400 without mods.

Thanks!

the pistons with the least resistence will always move out first, its very rare to have them all move out the same.

as long as nothing is binding and your brakes work well there isnt anything to worry about.

They need a rebuild. The pads are worn out very unevenly, a few of them are very hard to get pushed back in as well.

2003 600RR calipers fit. I forget if they're SP1 or SP2 type, but I think the 1000RR had them too, before everything went radial. You may want to put a slightly larger master cylinder on, some people find the feedback on the stock one to be a bit spongy with the bigger pots.

Beautiful, just got a reply from the wreckers for 2003 600rr calipers.

They're asking $85 per caliper and $125 for the master cylinder, I'll see if I can find anything cheaper but that seems like the best option I've found so far.

Edit: looked at the master cylinder for the CBR600rr looks like it might not even fit, as it has the reservoir built into the master cylinder.

I spotted that, so eventually I managed to get myself an early FireBlade one that has the reservoir on a bracket like the stock NC35 one. What sort of Dollar are you referring to? I got a pair of calipers, stock NC35 m/c and res, and a pair of braided lines from a seller on eBay for £74 plus delivery!

Aussie dollars.

I'm in no rush, so I'll keep an eye out on ebay over the next few weeks too. Can't believe how much wreckers want for the master cylinder though.

[wogstaa]

I went to the wreckers today and picked up a chain adjuster and some cbr 954 calipers. Didn't get a master cylinder though.

The problem with buying used is you may end up having to recon them any way with new seals and possibly pistons. hope that is not the case though...

[wogstaa]

Yeah, I'll have to pull the pistons out and check out the seals, give them a good clean while I'm there.
I'm not sure whether the RVF stock master cylinder will be ok with the bigger calipers though. May have to find a bigger one.
