will a nissan front caliper go on a 96 S1 or do i have to swap the master cylinder too? I looked in the vault but didn't find a good answer | ||

Yes  | ||

You may want to find out what size your master is - that will affect how efficient your new brake will function. Supposedly the hot Buell set-up is the Nissin caliper with the newer 1/2" master. The older 5/8" master will work just fine, just not give you as much braking power. But it'll give you shorter lever travel, so there you go  Henrik | ||

Tod Are you talking like the front caliper off a 350 Z?  | ||

nissin/nissan whatever  | ||

no just looking at putting a nissin caliper from a newer tuber on a s1 | ||

the newer 1/2" master. The older 5/8" master will work just fine, just not give you as much braking power. But it'll give you shorter lever travel Please clarify Henrik. You mean the pre 98 S1's master cylinder which was the one that required very little pull to work the brake? If so, I didn't realize there was a difference in braking efficiency between that and the later set-up. I thought the difference was brought about by customer demand for a more, shall we say user friendly brake, and nothing to do with better performance. In fact isn't the early set-up better performing in terms of braking force? I've always fancied the idea of using the earlier master because I liked the feel of that 'grabby' front stopper. Ever driven a Citroen with hydra-pneumatic brakes? If you have, and liked the way the pedal felt, you'll know where I'm coming from wrt the S1's earlier set-up. Rocket | ||

No, haven't driven a Citroen, but ... Given the same amount of force "X" on the brake lever: 5/8" master cylinder; force "X" applied to larger area = lower total pressure in the brake line = less braking power applied to the rotor. However because of the larger master piston area, more fluid is moved through the brake line given the same amount of lever travel. 1/2" master cylinder: force "X" applied to a smaller area = higher total pressure in the brake line = more braking power applied to the rotor. Less piston area moves less fluid at the same amount of lever travel. So, I guess, referring back to your post, that the 5/8" master would be the one requiring little lever travel to activate, but a firmer pull to achieve full braking force. The 1/2" master may be easier to modulate, because it would require more lever travel before activating, and again more travel before getting to full braking power. The 1/2" master would provide the most braking power at a given amount of force applied to the lever. That said, I don't think that means one is better than the other. Example: For systems with more or larger calipers, you'd need the bigger master cylinder to move more fluid, so that you didn't end up with too much lever travel before the calipers engaged. The dual calipers would make up in braking power for the lesser pressure exerted by the larger master cylinder. I *think* that answers the question Henrik (and I *hope* that I got it right  ) |
