I have a 73 Commando with a Hyde racing front caliper, a 13" Hyde disk and a stock master cylinder that was recently resleeved with a stock 15mm piston. The braking performance of this setup is pretty bad and requires a huge amount of effort on the brake lever to get adequate stopping. Additionally, the lever has a rock hard feel with very little sensitivity.
I have heard that resleeving to a 12 or 13mm piston in the master cylinder will provide more mechanical advantage, which will require less effort to stop and also give better feel. Does anyone out there have experience with this type of a resleeve? If so, please let me know how it works and where you got it done. I do want to retain the stock master cylinder for looks.
I also just read that some racing calipers actually use a smaller diameter piston than the stock unit. In this case, more lever pressure will be required and by using the Hyde caliper with the 15mm piston, I may have a set up that actually requires more force to stop than the stock set up. Any thoughts on this?
Thanks for any help you can provide.
