Is anyone familiar with an aftermarket Rear Rotor for the Harley Trikes. HD Rotors are $256.00 each. Doing research I find very similar rotors that fit older Mustangs and Mazdas. The rotor is a typical 4 lug Top Hat rotor. I find it hard to believe that Harley designed that rotor from scratch. I believe that they are for some previous Auto or something, just trying to find out what. Any help will be greatly appreciated. Thanks Mike
 
GREAT question Mike. Does anyone know? Could help us all down the road.

I agree, there must me an aftermarket or automotive affordable replacement. Keep looking. Please.

When I purchased mine the price was for the pair of rotors.

I think HD changed the composite material in their rotors for 2013.

Last year a friend working in our fleet garage turned my original rotors because they had some serious grooves. They didn't turn as auto rotors would. The trimmings came out like steel wool. They were able to be turned within specs but not as smooth as you would expect. I still had plenty of braking after turning the rotors and installing the Lyndall pads.

do you know what years for the mustang and mazdas
 
i just found this thread because i just bought a TG ....Has anyone found out EXACTLY what rotors from the Escorts or Fairmonts match ??? ... i am close enough to say it seems the circa 2000+ Ford Escorts are the same bolt pattern and diameter. if anyone has an old TG rotor, i made a diagram and need some measurements to verify as because since i just bought one, i have not yet pulled mine to measure, which i am willing to do as soon as i can. Its in storage beacuse its freakin winter here in Pittsburgh still ......... I am very close to matching them and will be glad to share... until then..... :Shrug: ....

Welcome to the forum. I will be pulling my rear rotors off in the next two weeks and be happy to map out the measurements. We all will benefit by finding a more reasonable ($$$) alternative. I'll get back in touch as soon as I have them removed.

The next question for the rotors:
Can you mount the '14/'15 rotors with the later bracket (ie '14/'15)for the caliper on the previous years? This would give better braking from the larger rotor.
If the automotive rotor is larger diameter maybe with the later caliper mounting bracket ??
I do know that DFT on their IRS kit for the TriGlide, is using a larger dia rotor with just a different bracket to mount the stock caliper. The only problem with that is they want $650 for rotors & brackets.

The mounting bracket on the axle is the same, caliper has changed and the mounting bracket for the caliper has changed. The newer caliper won't permit the use of the parking brake on an older TG. Not sure if the cost would be worth it, complete assembly with mounting bracket and brake pads is MSRP of $399 each.
 
They do have a different caliper for sure which would probably have different mounting holes also so using the old caliper on the later bracket might not work. Too bad a person can't get access to any drawings for the parts.
The only time to consider a change would be if you needed replacement on your one dime.
I don't mind mine now that I have the EBC pads on. The stock was an accident waiting to happen.
I wish MOCO was forward enough to offer an upgrade to previous editions in the name of safety. Even if you had to purchase the upgrade. But they are too busy selling the new editions. Just keep spending on their "T" shirts......

The bracket on the axle which the caliper mount connects to is the same PN for the 14 and later Triglide as it is the 13 and earlier. It leads me to believe it will fit if the caliper mounting bracket is also installed.

Thanks. Measurements would be appreciated. Email me and I will give you the form of the parameters I need measured and i can get this figured out for all of us....... (sesenn7) and that's at gmail. Let me know!
 
rear Rotors on Tri Glide

Ok... after some help from my friends ... here goes.... rear non vented rotors from a circa 2002-2006 Ford Focus are a close match. i say close because from measurements given of this stock rotor that sells at NAPA for $14.50, they need minimal machining to match. Also, rear vented rotors from a 86-88 Ford T-bird turbo coupe fit, if machined. Harder though, due to the vented rotor - they would have to machine the whole back disc off - one person verified this method and did it. Wish i could have marked the blog, but i know what i read.

I have yet to physically verify this for myself, but i am pulling the rear wheels today to check the brake pads because i rode home last nite WITH the parking brake on, only 10 miles, but thats another story - i have the capability to machine and drill the rotors if this works... and for $15, im thinking its worth a try. And if it does ....

should be problem solved. NOW - IF - i cannot machine these, i will take to one of the machine shops i deal with at work, and im sure with the machining it could only cost me around $50....so add it up ... $15 x 2 + $50 = WAAAY ahead of HDs price and probably a better product as i will have them drill and slot the rotors also.

Take it with a grain of salt - this to me is all STILL a project that i have not completed, but i know im on the right track. Check it out for yer selves. Heres to experimenting!!

:LordHelp:
 
I have heard in the past that some owners have drilled out there rotors..I do not believe you will feel that much of a difference in stopping..

I believe these are hayes brakes..Maybe contact them for advise..

I'm waiting for your results. Sounds very promising.

What do you mean - no difference? You dont think drilled rotors would improve longevity, as well as cooling quicker? Better stopping? And what if you use a ceramic(havent found yet for TG) or full sintered pad? Works on a car... why not bike? Especially trike...?

Do u mean as to say the stock rotors on the Harley Trikes are 'Hayes' brand? For Bicycles??

Not an argument, just trying to understand what yer sayin....

Lets hope Gorilla ....

I'll be interested in the results here as well. Definitely not going to replace with stock Harley rotors when the time comes.

Also wondered if going to a caliper with dual pistons would be a good improvement, mainly with the lyndall pads because of their greater width. Also because of the large difference in wear on the stock pads from the leading and trailing sides of the pads. Anyway, just a thought. I'm not sure if they even make a dual piston caliper for these yet.

It may help cooling but improve longevity on the stock rotors and stopping faster not IMO.

Sure you can use different type of pads go for it let us know how they work out. :D

Yep Hayes makes brakes for all kinds of vehicles.

I would use a 4 piston caliper and update the master cylinder to help the stopping of the trike..
