I'l get to the point, whilst preparing my srad 600 for trackdays i need a new master cylinder & lever assembly for the front brake,
(the old one didnt fair to well when asked to fight for it life against a telegraph pole! ooops:laugh2)
i seem to be finding none for "old" type calipers but plenty for "radial" brake systems, as far as i was aware the only difference between the two brake systems was the position of the caliper, radial being set at 90 degrees to the fork leg & old one fitted to the trailing edge of the fork leg......... so can i use a radial master cylinder & lever system on my srad??
Or am i living in a world of my own again??

Yes you can use a radial Master cylinder and lever :grin2 It's actually quite a popular upgrade on all bikes without radial brakes. I don't know the details but the master cylinder works in a more efficient manner.

Just make sure you match the lever/master cylinder to the calipers. On the master cyliner (D'oh .... the bit that does the pumping up by the lever) they have different ratio's which should be stamped on the cylinder. If you mismatch them (well.....if they are way out) the brakes won't work as well. You need to look for something like 9:1 etc.
I think the number on the master cyclinder is the bore size. Usually about 5/8ths or something. It was a popular upgrade to put a fireblade master cylinder on the old steelie to increase braking performance.

radial master cylinders are normally stamped, the most common are 19x20 and 19x18 the first bit is the bore size and second part is the distance between the perch and the part of the lever that push's on the rod were the adjuster is, most seem to favor the 19x18 as the other one does give you a very instant hard brake , every one recommends the brembo unit but you can use later suzuki radial braked model master cylinders theres a ducati one thats good but im sure doodlebug or lateshift will give the info on that because I cant remember :grin2

If im right the 19X20 ratio lever is better braking but harder to pull on the lever. The 19X18 is obvioulsly a bit easier to pull.
These are the two ratios suitable for a twin disk set up...any others and the braking will be cack!!

Yep fitted the unit from a 999 to my TL, completely transformed the brakes, looks better too :)

I knew the numbers meant something.

Or you could use a radial master cylinder off any production bike out on the market at the moment (rather than go for an expensive one), they should all work well enough on the older brakes.
Failing that look for a 16mm or 5/8th axial (standard) master cylinder as they give a lot more feel than the standard 14mm ones that are found on most of the older bikes.
The ones off the newer ZX6R's the Fireblades etc are all pretty good upgrades and a lot cheaper than most of the others.
