Upgraded my Brakes
#11
Sorry for the late responce, I worked a double shift today so lets see if I can answer some of these questions.
1.The Parker hose comes wrapped with an outer rubber coating, so they look like just another hose from the outside.
2.The rotors are vented
3.I modified the union (if you will) where all the lines run to.
4.I tested braking distances before and after,the results were positive.
5.Steel braided line have no expansion, therefor generating more direct flow.
6.Most of my answer could be more detailed but I ARE TIRED.
7.It cost me zero dollars for the hose and fittings.
And on that note I will leave you with this,I'm know experimenting with making a kit for those who are interested.
peace out Rictor

Guys, yes I understand that braided line doesn't flex. But, rubber line does not balloon to any degree, particularly with hand pressure on the master and no brake booster of any sort. Would braided lines make a difference on such a relatively low pressure system? I doubt it very much!
Weedy,
Sounds to me like the caliper (with a "P") isn't up to scratch yet. If the rebuild made a difference then you are barking up the right tree. I would crack the caliper open and have another go at it. Take close note of any scoring and corrosion on the piston and the housing, scum buildup etc. Make sure things are dead clean when reassembling.
Could it be a hose??? Possible. I have seen hoses break down and the inside rubber clog the hose. Mind you this was on a 35 year old car I was restoring. I would have a look for a hose that may have been pinched or crushed at some point. Possibly the hose that runs down the handlebars.
Good luck.

In my particular case they did. I was dissappointed initally with the HPD spit brake kit. It was a nice feature to have independant front and rear brakes, but the stopping power had not improved much.
On the OEM brakes the rear system is comprised of three sections, making it inefficient. For starters I scrapped the foot pedal and lines. I use a 50" line from the HPD master cylinder running along the frame rail. Almost at the battery box I use a 3-way fitting to run two 32" lines to the rear caliper, thereby using 100% of the caliper with one pull.
Even with the HPD split kit you are only using 50% of the rear calipers capacity, unless you use both the lever and foot brake simultaneously, what a pain.
On the front I run a 30" lint to a 3-way I mounted on the frame cross member (between the struts), then use another 30" line to each caliper.
The hardest part of the project for me was geting the right fittings.
