just a thought... eventually i was considering upgrading to some wilwood 4 piston calipers front and rear. i could do this sooner rather than later if i could use a bug master cylinder with them successfully, as it would save buying the uprated CSP master cylinder and fitting kit.
the calipers i want have the choice between piston diameters of 1.00" (25.4mm), 1.25" (31.8mm) or 1.38" (35.1mm) for the fronts, and the rear handbrake caliper has 1.00" (25.4mm) pistons. if i used a stock bug 19/19 master cylinder, to keep the bias right, would you suggest something like the 1.25 for the fronts, and 1.00s for the rear, or the same front and rear then make adjustments using a regulator valve? mabbo Last edited by mabbo; August 26th 2008 at 06:10. Reason: added piston sizes in mm's |

I would stick with a standard bug m/c but make sure its all working 100%. In a panic situation locking up the front brakes is infinitely preferable to locking up the rear so the Empi kit is intrinsically safe. However, you can't get maximum redardation because the rear never comes up to full braking force 'cos the front locked up long ago. Ideally, maximum stopping power will be acheived with both wheels on the verge of locking up. Using a balance bar arrangement is the best way to dial in the front/rear proportions. Quote:
I often see brake systems in bugs that are hugely over spec'd and more appropriate to very fast and heavy track racing cars. Most of these installations have poured money into just one end of the braking system without considering the whole (mainly I think that 'cos most of it is not visible). evilC |
