six piston caliper

[pddredduece]

I have a 2005 Deuce. I installed Harley floating rotors front and rear. These are the tear drop rotors. I also am using Lyndall pads front and rear. I am looking at a six piston caliper for the front brake. Will this improve my braking? Can I use the stock Mastercylinder? Thanks

Depending on the manufacturer... PM can use the stock mastercylinder, BUT that question should be asked of the tech team of the brand you're thinking of purchasing...

Yes, but I found that going to a ceramic composite rotor (at less than the cost of the caliper) will do the same or more.  These are the guys that make the pads you're using.

I run dual 6 piston performance machine calipers on my Deuce with Lyndall pads and composite rotors.  I went with performance machine primarily because of the differential bore design.  For me its about a light touch and distributing the heat among all the pistons.  They have performed flawlessly to date.

ThumperDeuce I see that you are running some pretty special wheels behind those composite rotors.  What is your overall impression of the new package of calipers, rotors and wheels compared to stock?  Is there a real noticeable performance improvement, or mostly the satisfaction of knowing that you are using the best?

I am a big fan of reducing rotational mass.  I've spent a lot of effort lightening up everything that turns.  I've also stiffened up the suspension and as a result I have very good feedback from the road surface.  The difference from stock is noticeable!  It is very responsive with a light touch, not twitchy, and is extremely stable at high speeds.  I have no regrets about these mods.

The only thing that I don't like about the PM calipers is that they don't have boots to help keep the pistons clean.  I guess this is common with HD stuff though.

switched out the SS rotors on my flhx and dropped 9 lbs rotation mass (there are different theories of the equivalent mass but many would say it equals 100-130 lbs of unsprung weight).  They stop great but on a bagger the biggest difference is the reduced gyroscopic effect, it makes the bagger in the corners feel more like a Dyna, very responsive.

In my experience, those rotors are no better than stock. It's my opinion that HD should not call them "floating" either. They are simply a 2 piece rotor. The center and friction ring do not move, so I don't see how the friction ring can float.

The best braking I have been able to achieve on my bagger so far has been a 13" rotor and 6 piston caliper. Composite rotor like what Thumper is using is next for me.

Interesting question and considering that I've been putting the parts together to switch over to the Jaybrake Extreme six piston calipers for my 03 RK I though I should find out.

I called Jaybrake up and asked their Service Tech if the stock master cylinder would be up to the task using their 6 piston calipers, his answer was "sure no problem".

He said that it would only be an issue if I was going from a single caliper set-up to a dual caliper set-up.

My scoot came with dual front rotors.  I don't know if it has a different master cylinder from the single rotor version.  The part number is 45298-99.  It  pushes the dual 6 piston set up fine.

I use a stock master cylinder on my HHI 6 piston as well. No issues.

Sorry to sidetrack but can I see some better pics of your bike?
