Topic: Brake upgrade ... what have u done for better brakes?

Techy5025, expanding the brake lines expends or wastes energy, energy which otherwise would be exerted on the slave piston.  I agree the difference in pressure applied at the caliper may not be quite as substantial as perhaps I made it sound, but true nonetheless.

However I do take your point, the benefits of the braided lines is more based around lever feel, and lever to caliper response.

CB925....Both very interesting.  I didn't realize what the actual bursting
pressure was for the lines.  I guess at over 3000 psi we are safe with
hand pressure.   

I just wish the stainless lines matched the rubber ones better.  The
diameter of mine is much less than the rubber ones....maybe a thicker
outer coating.  I would never go back to the originals though.

Here's my set up:
CB 1000 forks/brakes, 35mm tubes are longer than 550.
Dual piston calipers fit the 550 disks diameter "drilled looks nice"
550 disks are too thick, had to be 4mm from 7mm
CB 1000 calipers are too wide for stk 550 hub w/2.15 alloy rim, spacers/washers needed
 I need to get lower triple tree welded up for second bolt in dual brake block.
I need to finish this 20 yr project. Gentleman's Express Gen II

For me (75 CB750F), I went to a 2006 GSXR 600 master cylinder and braided stainless lines.  You can definitely gfeel the difference.  Not sure if it's the new cylinder, braided lines or both that make the difference.  Don't be shy about mixing and matching makers is you're not doing a full restoration.  The only downfall is it doesn't have a mirror mount now.  Oh well, that's what barends are for.

  I see that this thread is mostly 500/550 bikes but I'll add this for any 77-78 750F owners. '82 750 Supersport calipers/mounting brackets are a bolt-on upgrade. Dual piston calipers for that "little extra" stopping power if you ride hard. Better selection of brake pad composition as well. The pads do not contact the inner 1/3 of the '78 disk so I got a set from a '82 which appears identical except that material has been cut away from the inner 1/3 portion making them lighter. They bolt right on the comstars. I don't see any problems using the '82 disks but won't be installing them for use for a few months. I've been using the calipers for the past year and very happy with them.

That got my interest.  Will those fit on a 75 CB750F?  I'd love to have some lighter brakes and biggger calipers.

I just changed the fluid (old, crappy DOT3 to new, clean DOT3) and bled mine.  Made for a heck of a difference.  The 750 set-up on my 550 does sound intriguing. My OEM 550 work OK for me now, but then I'm a pretty tame rider.
