New rider brake disk help.

Riches22 · Jul 28, 2017

Evening all, sorry if this is posted in the wrong place I'm new to the forum and supermoto's.
I've just bought myself an FS650e today and love it to bits already but got it back and noticed the Beringer front floating disk has quite a bit of play front to back. I can rock the bike forwards and back with the brake held on.
This seems excessive to me so my question is how available are the Beringer brake rotors for these older bikes (2004) and how much is one likely to sting me.
I should add that I haven't ridden it yet so can't say whether it affects handling or not yet, maybe getting ahead of myself a bit.
Cheers for any help.

Make sure the rotor is tight to the hub and has not came loose. Make sure the caliper is sold and not loose. If when this is done and you still have play then your rotor is worn out. The spacers (locks) that hold the disk to the mount might be worn out. You should not have movement. Rotor should be solid to wheel even though it is full floating it must not have play.

Thanks for the reply mate, yes unfortunately it's either the spacers or the rotor itself that is gone. I'll look into finding another one then. Thanks.

Those Beringer discs almost always have some play in them - I've never come across one that didn't. A few mm of side to side play is perfectly normal with them - front to back play not so good. If you're lucky it will just be the bobbins - about £35 for a full set. Look up Supermotodaz, he can sort you out. Take your bobbins out and look for signs of heavy wear on the carrier where they sit. It's ally, and they can wear out. The rotor itself will NOT wear out - it's cast iron! Those discs are VERY expensive new - plenty of other options about if you need to replace it. Remember it's a 310mm though, many people assume they're 320mm.

Thanks Bludgeoner, the carrier does look worn unfortunately as I can see the aluminium peened over under the pins but I've spoken to taffy on the phone and going to try the pins first as like you say will be a lot cheaper to start with and may get most of the play out. The bike has around 240 hours so not too surprising I guess. what sort of drop in braking performance if any, would you expect to see by changing to a different disk and carrier? Cheers Ben.

Very little if any (depending on which disc you get!). Beringer discs are very good but their optimum performance is only really found in race use. If you find it's still too loose with new bobbins, I might be up for a swap/px deal with a Braking wavy 310 disc (also very good). Keep the old bobbins just in case!

When I put a sumo wheel set and brake on my old '95 Husky 610 back in the day, the EBC rotor came with an extra set of rotor buttons. After a certain break in period, you had to swap the originals with the supplied new one's. I was told this was because as the rotor went through several heat cycles it required buttons with tighter tolerances. Of course that was older technology and my not apply here. It did get pretty sloppy early on which the tighter buttons fixed.

How did you get on with this mate? New bobbins sorted it?

Supermotodaz does the disc centre kit for £150.00 with bobbins I think

I can now do an EBC 320mm disc conversion for the 21" front on the pre 2000s. bugger it took some work but I got there!! I have the caliper carrier, 4-piston caliper, pads from a little KTM200, the correct offset and a wheel spacer to suit!!! da! da! not sure why you would put a 320mm on a 21" front but there you are....
