Watch this space... I have the bracket design & some prototypes on the way. Once tested I'll feed back & we'll see how many others want them on here & Oldskool suzuki to see if it's feasible to get a big lot made up.
The prototypes I'm having made are Aluminium, they should be T6.
I may well have a set I can send you to test.

Your strap doesn't scare me as such... but you do need to keep an eye on it for stress cracks & I would be happier if it triangulated to the other bolt hole as well so stop any possible rotation.

What thickness did you use for the strap?

Dan :)
 
1/8 inch. Same as the caliper bracket itself. It has not moved, or cracked in the year they've been on there. All the real nasty forces are on the upper bracket anyway.
I was checking them daily for the first two weeks, then monthly. I've stopped the bike from 100 mph + occasionally, and from 70 mph daily. Nothing has happened. I trust them, but they are on the ugly side. Something that looked a little less homemade would be nice.

If you end up having some made, I would love to try a set.

Back on page 3 of this thread I stated the GS1100E master cylinder was a 5/8" bore. Using the chart on http://www.vintagebrake.com/mastercylinder.htm with (2) 38mm single piston calipers, the ratio comes to 11.46.

Single piston calipers are much happier in the 14:1 to 12:1 range. Disc and wheel diameters, as well as hand lever ratios, must be considered.

A 14mm bore master cylinder puts you at a ratio of 14.73 - closer to the mark.

I'm pretty tied up with things now, so if someone wants to call Michael at Vintage Brake and run that by him, I think it will help confirm this replacement master cylinder is the real deal.

We talked about it , he seemed a little distracted (he was trying to write up the order or pads). We also discussed surfacing the disks and as we were finally ending the conversation he lights up and said "wow you are really going to notice the upgrades". OK So now I'm really looking forward to it. \\:D/ Safety First :-D

83 GS1100ED brake upgrades
FERODO Sintered front
FERODO PLATINUM rear
Fresh surfaced rotors
New 14mm Master Cylinder (looking for someone else to verify)
New Slave cylinder kits

Existing SS lines

With 70% of the braking power coming from the front brakes...why not run the Platinum pads? It's what I used, they're better than Vesrah organic (Kevlar) pads for sure and stock Suzuki.

I don't have any experience with the sintered Ferodo. If Michael Moore says they're soft and sticky...I'd worry less about it.

Adam, I'm bringing the 1000 to BC this year. Remind me to let you ride it. You have to try the brakes out.

Michael Suggested them.8-[ At first I was concerned about rotor wear, but he explained that they were much less aggressive that other brands and comparable to other brands organics in terms of rotor wear. He also said there is a very aggressive initial bite. So I figures, I'm not really looking for a lot more lever travel, but if the bite comes up fast on the sintered pads, then that with the 14mm MC might be a nice combination for 1-2 finger breaking.

As I mentioned he went from a little preoccupied to surprisingly excited that I was going to see a big upgrade with the combo. :-D

I'm most likely bringing the CB500F, but I'm not 100% sure yet. I'd like your opinion on it's brake setup.

Jim - I like your plan. You'll be super happy with the newer, and more importantly appropriately sized master cylinder. I rode my CB to work this morning and I love squeezing the front brake lever now. :)

gday guys, on my 1100et, im using the usual ss lines, standard calipers,gs1000 master cylinder, but the discs are from the1150e, as they bolt on to the 19 inch mags, and there is no spacing of the calipers involved, and this settup gives good brakes, and plenty of feel, regards.

Hi
Great info; was wondering if those GS1150 rotors are any larger diameter than the GS1100 and why they would provide more breaking power(if not larger). Also assuming you did both front and rear rotors?

You mentioned GS1000 Master Cyclinder; is that the 14 mm version?

TIA

Posplayr
 
gday mate, same diameter, but they are floating, which helps when they get hot, i also used the rear caliper of the 1150e, but you have to turn up a couple of shims, to space that properly,on the carrier, regards, ps. will try to get some shots downloaded soon.
