Title: Brake disc swap CB550F ---> CB750 K7
Post by: notobikeparkingtax on November 28, 2010, 09:55:06 AM
Anyone know if this is a straight swap ? I've sent my K7's disc off to Len Cooper to have a cast iron disc fitted and it's already a week overdue with no sign of it being done. I want to ride my flipping bike!!
 I can get hold of one off a CB550F, part numbers are different but I'm not sure if that means it wouldn't fit at all or that the carrier is painted a different colour!

Thanks in advance,..

If you utilised the 550 caliper bracket then you could use the 550 disc.

Thanks Yoshi823,, worth knowing.

Having been told by Len Cooper engineering that the brake conversion would be done in 3 weeks, my brake disc should actually be back with me next week...maybe. That'd be nearly 2 months after it was received by them.

Seriously..not a happy bunny right now. If it was going to take two months I'd have appreciated being told that at the beginning.

Back in the late 70's there was a firm that did cast rotors to bolt onto the standard carrier and i got one for my 500 four, i found that it made no difference in the dry and in the wet the brake worked and locked up sliding the front wheel out from under me!!!

I eventualy went to twin standard discs with one caliper in front and one behind (this was before the 550 came out with mirrir image sliders) plus a Goldwing master, that made the tyre howl when braking but never locked on me

I remember that advert being in 'Bike' magazine & possibly in 'Superbike' mag. It seemed like a good idea at the time, particularly because the brake pads of there day were not that good...until Ferodo brought out a worthwhile compound.

There's a forumite on here that has a CB750K sohc with a 500/550 front disc on it...the 750 is quite a lot bigger & it was this that I noticed.

Pfm I think do cast disks to replace stainless on Bmw's so that's where I'd look for cast disks. I deffinately think they have their place if you tend to use the bike in all weathers, though I just drag the front brake on almost pernemently if I get caught in a real downpour on the 500/4, onece warm the standard rotor works fine even in the worst Welsh / Yorkshire downpours, particuarly bearing in mind the tyres get less grip in those conditions and when I onece was on the motorway from Leeds in such conditions visabilit was also down to nil too. Brakes in standard form were still good for hauling a bike, sidecar and spare bike in bits and tools to put spare bike in bits all to a halt at motoway speeds - reduced speeds for conditions as I like to be able to stop on the amount of road I can see!
