Front brake upgrade GS850

I have a 1979 GS850 that needs a front brake improvement!

A number of questions spring to mind.

Will the ventilated discs from a GS1000, 1980 onwards help?

Do I need to change discs and calipers? If so what fits?

Has anyone upgraded with anything other than GS parts?

I did read somewhere that CBR600 calipers do a good job.

Should I just fit a complete usd front end?

Advice appreciated please.

Thanks,
Chris
 
Your best upgrade to your stock set-up would be steel-braided brake lines to avoid the expansion inherent in the rubber factory line. That's a more basic improvement than anything else.

GS rotors off post '79 850 and 1100 models are a direct bolt-up as I understand it. But I think the slotted rotors are only a marginal improvement, if at all over a well-maintained stock '79 set-up (from my limited experience riding post '79 GS models). I have no experience with the rest of the subject.

I am looking for a vast improvement in the brakes!
I suppose I will have to go the USD route from a GSXR.
This is the GS850 as she is now.

Ah, I've seen your bike before. Interested to see what upgrade you finally come up with.
 
Mid 90's Kawasaki Ninja calipers, ss lines and a 14mm master cylinder bore.
 
I don't think you necessarly need an USD fork to improve the brakes. There was a thread in the performance mods section where someone grafted on some dual piston calipers which I suspect drasticaly improved braking power.

Thanks guys.

I thought that while I was doing the brakes I might as well give the front end a bit more of a presence!

ZXR1200 seem to be the right length.

I would prefer a Suzy front but they seem harder to find (gsxr 1100, 89-93 vintage anyone?)

I will post a pic when it's done.
