Harrisson 6 pot with HPN rear....
Sounds good, I know it is relatively bolt on which is nice, and well finances do make more sense than a stay at the formaldehyde resort...
Any thoughts on other brand 6 pot or am I being cheap ?
Cheers

I'm running the 320mm rotor and a new stainless brake line on my 1981 G/S... much improved over the original. Currently I have some cheepo ebay brake pads that are a bit hard and I plan to change to Galfer green's or blue's shortly.

I would say I never use more than 2 fingers braking... in the US this option was much less expensive than the Harrison.

I'm bumping this thread up to see if anyone has any thoughts on a second disc for redundancy?

Is this a valid reason for another disc - or if you've hit something hard enough to damage one, will you have greater problems than a damaged disc?

IMHO the chances of hitting a disc hard enough to damage it is minimal, after all the disk is small and placed between the fork and the wheel.

The fork is not up to better brakes anyway

I've not read all the posts, so apologies if this has been suggested, but if you want a cheaper option to improving brakes, could you not get braided hose, an over-sized front disc, and a spacer bracket made of the existing caliper? Failing that a caliper with more pistons from another BM?

I changed the disc on my XR400R and used an ally bracket and it made a healthy difference.

I once also upgraded the twin pot calipers on my CBR1000F to the Fireblade 4 pots from the same time. I had two spacer brackets made and it made a huge difference!!

If I knackerd a disc that way, I'd simply remove it and rely wholly on the rear.

Not ideal, but if you adjust your riding accordingly you are still mobile until a fix is possible, and without too much impact on safety...

The final move
After a bunch of monkey wrenching and part swapping, I decided to go with a 320 mm conversion and braided line.
With my parameters and budget cost it came to be the best option.
The dual brake attempt left me with some worry on the shear force that the bolts would have experienced under load, even if it was just in my head it was enough of a concern. ( not something I want to worry about riding ).
So there you go, and it works just grand.
Thanks for all the help and insight.
Cheers
RA

Hello. Do you know left hand caliper OEM code?
Thanks
