Braking upgrades for GT750A

Post by EvansWard »

I find the stock dual disc braking system on my 76 GT750A to be lacking even with the stock master cylinder changed out to a 14mm unit from a Suzuki V- Strom. Reading about the concerns over wet weather braking conditions has me in the process of upgrading the braking. For the time being, I want to retain the stock GT750A forks and front fender. I did purchase some nice used cross drilled and balanced GT750 disc rotors. I have searched and have done a lot of reading on this subject but it’s not all 100% clear to me. I’m now looking at other Suzuki calipers that will bolt up to the stock forks in the stock position. I will totally disassemble whatever calipers I purchase to restore and rebuild with all new parts and pads. The first pic are the cross drilled/ balanced rotors I purchased. The next 2 pics are 1981 Suzuki GS650G calipers, pics 4 & 5 are Suzuki GS750/1000/1100 calipers, and the last 2 pics (pics 6 & 7) are calipers from a 1982 Suzuki GS1000. Which of these 3 different brake calipers will bolt up in the stock position on stock GS750A forks? Down the road, I want to replace the stock forks with those from a GS650G and use some Kawasaki EX500D calipers in the lower position but don’t want to change front fenders. Can anyone answer my question about which of the 3 caliper types I referenced will bolt up and which would be best? I also already have stainless steel braided brake lines. Much appreciated on any help and feedback!

I used SV650 calipers on mine with machined adapters and CBR600 F3? rotors for a huge weight saving. If I did it again, I'd use the light rotors and a set of GS1100 forks and fender or something lighter. GSX600 Katana forks are lighter and the lightest I found so far are FZR400.

Thanks for the info Richard- much appreciated! I’ve admired your work and brake upgrades on your website. For now, have decided to go with 78-79 GS1000 front calipers in the stock mount position using the stock GT750 wheel/ fender with cross drilled and balanced discs from a GT750. Eventually, I’ll change that to a set up using different forks and dual Kawasaki Ninja 500 EX brake calipers using the Salty Monk adapter kit. I’m sure I will have many questions when that time comes....

Why is another GT750 triple tree/ steering stem needed when going the Salty Monk all out brake upgrade?

No idea what a salty monk has to do with brakes or breaks or steering stems. Do you have a link please?
