Bias brakes

[Chris Wilson]

Just finishing a brake servo removal and making a twin brake master cylinders with in car adjustable bias bar setup for front to rear bias setting. Pics may be of interest, I am sure a simialr thing could be knocked up for SX's.

One way to get adjustable brake bais, although actually using it requires a little more skill than I have.

I saw your thread on Skyline Oweners, well I say thread, post with no replies last time I looked :wack:

Why do it this way rather than with a normal bias adjuster?
What advantage does the servo removal have?

Looks very nice. What's the pedal like with no servo?

I'll tell you later next week, when I have a turbo back on the thing!

I have replaced the whole braking system, discs, calipers, the lot, with uprated stuff and needed to get some effort off the back. I ran a pressure limiting valve, but they are a bit crude, and fancied doing it properly with in car bias bar adjsutment nd twin master cylinders, whose size i can play with to get the padal teavel / effort balance I want. Removing the servo saves weight! Also gives a better pedal feel. With the cams going in the new engine it will be short on vac to run a servo reliably at all speeds.

BTW, I have an as new AP Racing proportioning valve for sale in the parts ads section

Cheers, so the bais will be controlled by swapping master cylinders, with smaller adjustments then via a in-car bar which adjusts which cylinder sees most pedal movement?

Have to say your brakes looked cool (browsing your site) nice mix of Porsche and Aston Martin :thumbs: You certainly like engineering custom mods :thumbs:

[Chris Wilson]

Yes, cylinder swapping will only be needed to get the initial set up, then the adjuster cable and know (not shown in pics) will allow bias to be set for wet or dry, or full fuel load, whatever. I do like making bits and bobs, yes :)

Looks good, seems your not the only one though ...

Ahh, we're all at it are we? :) No welding, no drilling, no bashing, no pipes altered with mine. An hours job to revert to stock if it all goes horribly wrong and the pedal is like a sponge or a rock.... I hope it works as I have spent considerable time and money on it.

Well, I think the rest of the project, if you read that thread, is quite involved, thats just a small part of - fully seam welded, weld in cage, modded boot/race fuel tank, and more, and 600+bhp sure you'll like it.

[Chris Wilson]

It looks a proper job, I'd be very interested to see more pics and read about it, is he documenting the build? I have too many projects on the go right now, I need to get one or two finished!

Full thread here, http://www.sxoc.com/vbb/showthread.php?t=212668 loads of pics, if a little spread out through the thread. Engine was done last year, then the car causght fire so needed re-shelling :cry: its currently at Norris Designs being re-assembled.
