OK...
In an effort to solve the "two caliper stock setup vs. one 6 piston caliper-13" rotor" debate...I've email'd both Performance Machine & Hawg Halters.

Below is the email I sent both.
I'll post their responses when I get them.


Hello,

I'm considering changing my front brakes on my 2006 HD FLHX Street Glide from the stock HD setup to a single 6 piston caliper with a 13" rotor.

How much braking ability do you estimate I'll lose, if any?

Wouldn't one quality 6 piston caliper such as the HHI with a 13" rotor be as good, if not better than the current stock setup I'm now running?

Thanks for taking the time to respond.

 

you go bad piggy....but they are trying to sell a product so there reply might be biased.

 

Yeah,
I took that into consideration.
Hell, they may come back and tell me a better alternative would be 2 of their 4 or 6 piston calipers.
Hopefully they'll shoot back something unbiased.

 

Keep me posted as I am also considering going with the 6 piston PM brake. Depending on the HD dealer you talk with they both give totally different awnsers about the braking.

 

I do not know what they will tell you, but I can say when I switched my stock brakes on my 05 FLHRS for a 6 pot HHI and a 13" rotor, my braking effort(READ squeeze toe brake lever effort) lessened and my stopping power increased considerably. I got my setup from Bart at Cateye Customs ( a board sponsor) and used a setup he recommended based on years of building custom bikes. It served me well for several years and even got me some extra money at trade time.

 

OK...both PM & HHI replied to my email today.

Here is the HHI reply regarding the caliper debate.

Chris,



What we have found thru testing is no real loss in braking distance if retaining the stock size wheel. If you are changing to a 21” then you’ll lose a little due to the reduced tire contact but not significantly. The only other change is heat build in a single vs. dual. If you repeat the braking sequence the single will heat up a bit more but this is not a typical daily driving experience. The most important thing you need to do is change your brake master cylinder to a 9/16” bore for proper fluid volume and pressure.



Thank you,

And the PM reply...

Hi Chris,

I do not have a percentage on this application.

I would think it will be close to what came on the bike.

The 13.0” disc will help.

Thank you,

From depth of answer... HHI would seem to win this contest. PM really didn't have time for you.

 

Either he didn't have time for me...

OR

He aint gotta damn clue!



I vote for the latter.

 

Bad Piggy, great job, plus you added your own 1st hand experience which most naysayers have no experience but they are experts on there beliefs.
