Gidday All ... here i was thinking i was finished for awhile on upgrades and addittions to my 99 Springer but as some of us addicted to tinkering know the light at the end of the tunnel just differs in brightness , Lol .

Decided to upgrade my front brakes ... well it has been an interesting exersize to say the least ... as you can see i went with the tried and proven 6 piston PM caliper , i have the same type on my 08 Softail and found it to be very good ... the oringinal problem was the lets say oringinal cheaper rotor i had on was not up to the job of handling the extra stopping power of the new caliper and after 1 trip down the steep side of Mt Tambourine , { a twisty and steep mountain up here in Sth East Qld } , it warped the rotor and boiled the brake fluid ... which was a pity because i liked the look of the Super Spoke Rotor .

 

The discission was made to go with a Full Floating Rotor , straight out of the Harley Catalouge , good quality and the right price ... then the next problem arose , the Bobbins that are on full floaters that hold the outer rotor onto the inner rotor are about 3 or 4 mils sticking out from the face of the rotor which of course on a flat rotor don`t pose a issue , but the bolts going through the Caliper hanger into the PM caliper were protuding out just a little to much plus with anything customised there are always little hurdles to get over to get the desired effect ... so with a slight bit of grinding of the bolts and just a very small bit off the back of the caliper we got what i wanted ... maybe not as pretty as the Super Spoke rotors but a far better quality of rotor that also gives me that piece of mind when going down mountain ranges .

 

Of course i had to have a matching rear rotor ... { God forbid i have someting that dosn`t match , Lol } ... next small hurdle to jump ... being as normally people don`t seem to put a full floater on the rear they don`t run into the issue i came up against ... as the Rear full floater i put on is actully a front rotor the bolt holes in the rotor where the bolt heads are recessed into  are not the same size ... not a huge issue this one , all it entailed was a machining down of the bolt heads of the usual rear rotor bolts to the desired size and hey presto a matching full floater rear rotor .

I think if i had 1 not nessercerily bad thing but courious thing to say is the difference between the contact areas between the Harley rear Caliper and the PM front Caliper ... if you have a gander at the pics the Rear seems to have a bit more contact area as oppossed to the front but it works so for me thats all that matters .   

 

Not the greatest pic but lurking in behind high flow air fillter and old school fillter cover is a 42 mil Mikuni carb ... just livens up the motor somewhat from the standard 40 mil CV carb i had on there ... well lets see how long before i make any more upgrades , hopefully a little while , for my wallets sake , Lol .

very nice bikes mate and decisions decisions, which one to ride lol.

Lol ... tell me about it Steve ... my addictive nature has me wanting a Street Glide down the track plus a long held Dream of a late 50`s early 60`s Chevy Pick Up ... to many vehicles not enough

time ... but I do get out practically every weekend on both rides ... { Watching MotoGp today though } ... bring on early retirement , and a Lotto win wouldn`t hurt , Lol .

Hi guys ... anyone out there know where I can get some 12 V 23 Watt indicator bulbs ... they need to be the ones with the small globe ... can get the bigger type but wont fit into the lens area of the Bullet indicators I have on the Springer .

I can get 12 V 10 Watt ones that fit in the Lens area but they won`t flash ... of course I can get some Load Equalizer`s put on but was hoping to not muck around with wiring ... surly there must be somewhere in Aussie Land that sells them .

My punishment I suppose for getting indicators out of Taiwan ... although I didn`t know that at the time ... I`d buy a small box of them if there were some around ... you`d think with all the Tiny indicators guys put on their Custom bikes that there would be bulbs to suit .

Mate have you had a look on eBay?

Love the brake upgrade, that really put the icing on the cake. She just screams performance all over now. I do find it interesting that the 6 pot claipers on the front only have that much contact on the rotor. Id like to put a 6 pot on the front setup I'm going with, though anything would be a massive improvement from stock I guess. Have you looked at those rear brake kits to hide the brake and rotor on the left side behind the pulley? That'd be trick. Not really a mod worth it's money though

Hey Squid , thanks for the brake comments ... a much needed improvement over stock that's for sure , Lol ... have been giving the new brake set up a bit of a canning the last couple of weekends and so far so good ... would like more of a contact patch as mentioned above but I`m not complaining now that I have given it a good test .

I reckon PM could have made a dust cover for their Calliper , just to tidy up the look a little ... I reckon it is one other small thing I could whinge about if I was to be picky ... I suppose usually the Calliper is sitting behind the fork leg and doesn't get noticed as much as when it is out front and centre as I have it now .

Ended up scoring a bulb locally ... just one though and is working fine so far ... fingers crossed it won`t be a on going issue ... have another 4 coming in from USA as back ups for the future if any of the others blow ... hopefully not , touch wood .

I did check out those rear rotors you mentioned when I was Blinging out my other ride , the 08 Softail as I reckon it would have really set off the rear Ride Wright wheel and more importantly for me made it a shit load easier to get to the hub to clean instead of busting my knuckles every time I clean the beast , Lol ... my punishment for liking spoked wheels ... chose the more conventional route , but one never knows where ones pay pack may end up on any given week , Lol .

Got a Andrews EV3 Cam to go with the Mikuni now ... Fark did that little upgrade make a difference or what , hits high 2 grand in the rev range and comes on like gang busters ... for a Old Evo that is ... so much for letting the wallet have a brake , Lol .

So on goes the journey of addiction to spending money on my rides ... we only live once hey .

Watched a cool little you tube vid the other night called " Fifty Years of Kicks " 2 old guys , 71 and 61 , still riding dirt bikes and having fun ... one of the lines in the vid which I think was adapted from ShawShank Redemption was " Get Busy Riding or Get Busy Dying " not a bad motto to have I reckon , cheers .

I reckon the brakes look great with the bike the way they are now mate. Sounds like you're having a blast with her!

I had a look on PM website and I couldn't find the 6 pot listed for a springer. Do you have to ask for it or do any 6 pot simply bolt straight up to your bracket?

Hi Squid ... your right squid there is no official 6 pot Calliper for a Springer from PM ... I didn`t know about it myself until the guy who built my Twin Cam motor mentioned it ... what he does is takes a normal 6 pot one that usually goes on behind a telescopic front end from the right hand side , the throttle side and then flips it around to the left hand side , side stand side and locates it in front of the Springer front end .

We had one small issue and that was because after warping the cheap front disc I had on I chose to go with a full floater front disc , straight out of the Harley catalogue by the way and far cheaper than some of the more fancy after market ones , anyhow by doing this we forgot to compensate for the Bobbins that make up the full floater disc as they stick out from the rotor face by a extra couple of mils ... a small spacer here a small spacer there and the tiniest bit of grinding on the back side of the Calliper where the Bobbins pass the Calliper bolts and problem solved .

And as mentioned above somewhere the only other issues I have with it would be a cosmetic one because now that the Calliper sits in front of the down legs of the Springer the top of the Calliper is exposed more and I reckon PM could have made a nice little dust cover just to give it that all over smooth look ... normally when the Callipers are on standard telescopic front ends they sit behind the legs and aren`t so noticeable to see the exposed area .

But that is a small price to pay for better safer braking ... how is your new project coming along .

Thanks very much for the info TJU. I wanted to go 13" rotor with the 6 piston on my springer but I've decided to run with Lyndalls racing rotors in the black 11.5 composite rotor with a 6 pot caliper. I didn't know the telescope forks had the same mounting distance. Funny that though I was thinking of this exact same method earlier last night as no one seams to make 6 pot calipers for springer. I'm either going to go with PM or ISR. ISR are a couple hundred more but have a more rugged look which I like, but the black ops PM would look cool up against the black composite rotor

These rotors would of saved your mechanic a lot of head ache as the floaters are in the mounting hardware itself. The 5 studs that mount the rotor are the floaters with these rotors, so you wouldn't of had to shave anything.

That sounds like it will do the job for sure with those Lyndall Rotors , I was looking at them myself for awhile ... if you are still researching have a look at EBC as well , they seemed to have some interesting ideas also ... but I reckon those Lyndalls you mentioned are pretty trick .

Good luck with the build .

Is the front caliper fitted over the disc right, or does it need a larger diameter rotor? Maybe you've covered it before as only read back a few posts or the angle of the picture might be decieving.

You are more or less on the right track there Captain Hook ... back a few post I mentioned that the surface contact or lack there of is something that stood out to me as well , especially when you look at the rear Calliper / Rotor combination , but that is something that comes with trying something that is usually not used together .

I have had plenty of real road testing since and am convinced it is up to the job especially considering the awful feel of the standard single cylinder Calliper ... I may be wrong but from what I have seen of PM brake pads compared to other brands the PM ones do seem to be of a smaller diameter .

The larger diameter rotor suggestion is something I will keep in mind because as you probably know the larger the contact surface area for pads on rotor the better the braking capabilities ... thanks for the feed back .

Just glad you didn't get upset. The outside bit of the rotor has the most stopping power due to its leverage from the centre of the wheel so a bigger rotor will stop even better than it does now if there is pad area there being unused. Got no idea what rotor will fit as it looks like your already using the slightly bigger ones for a Harley brembo or touring models, they look a lot like my Fatbob ones. Somewhere there was a picture of what looked like a 6 piston Harley one, Been working too hard so can't remember exactly, but think it was something about a trike, Yours look good though, Hyabusa ones look good too.

Does a Brembo fit straight on there as there are spare RH side ones going cheap from the guys who take one off, they nearly always seem to take the RH side one off, must be so they can swap a Fatboy slider in there, wouldn't take one off myself. Does the caliper you took off only fit a Springer?

The single piston Calliper I took off is a standard 99 springer Calliper but not sure if it could be retro fitted to something else , most likely anything can be fitted given the right brain waves , Lol ... which I don`t always have .

I remember seeing that 6 piston Harley Calliper as well , wasn`t sure if I saw it here or somewhere else because I haven`t seen it on any of the 2015 models as yet but you might be on the right track thinking it is being used on a trike .

I think some guys take there right hand side Callipers off so they can open the looks of the wheel up and get a bit of Bling showing but if I had 2 front Callipers on I reckon I would keep them on ... ya can never have to much brakes I reckon .

Thanks for the ideas and questions .

I've done a lot of looking around and from what I can see no one makes a caliper bracket for a springer to suit a 13" rotor. But if you have seen something then by all means do share with me, because otherwise I'll have to make a custom braket to make it work

Gidday Squid , mate I hope I haven`t led you down the wrong path ... I don`t have a 13" rotor on my Springer , I have a 11.5" rotor on there ... the 13" rotor I have is on my 08 Softail Custom .

In saying that though I wouldn`t mind betting that some of the more ingenious engineers we have here in the Sth East of Qld would be able to sort out a bracket to fit plus have a look at a mob out of the USA called Vulcanworks.net ... they seem to make bracket adaptors and spacers for all sorts of things .

Hope that helps a little ... Tim .

Nope not at all mate. When you said you were thinking about a 13" caliper, I was just stating there's nothing on the market to make this fit.

It wouldn't be hard to fab something up though, it's practically just a plate with holes. That being said, it'd have to be spot on

Hey mate hope all is well. I was wondering with your front rotor what size you've used, 11.5 or 11.8? If you used a 11.5", would a 11.8" fit with your setup?

Gidday Squid , all good here , dealing with the heat in good old Sth East Qld , thank god for technology and air - conditioning , Lol ... I will check but pretty sure it is a 11.5 " rotor ... I will also have a look around to see what rotors come in the 11.8 " and maybe give one of them a go down the track .

How`s your project coming along ... Be safe over the Festive season and give those boys in blue a wide berth , don`t need to give the buggers any more of our hard earned dough .

Cheers ... Tim .
