I need front rotors - 5th Gen

I need front rotors - 5th Gen - UPDATE

I need front rotors. What are people doing these days, rather than dumping $250 a pop on each side for OEM? Anything aftermarket coming out of China that has been tested?

I have a good lead on some new OEM 6th gen rotors, and according to Service Honda, the part number for the 5th gen is the same as the 6th generation.

For OEM, front right, it looks like I need 45120-MCW-H11
For OEM, front left, it looks like I need 45220-MCW-H01

Just thinking out loud here.

 

I bought a set of 5th gen rotors off of ebay. It was several years ago but they were inexpensive enough to make it worth the risk. I would try that. Also, why do you need new rotors? Have you measured them? Are you sure they are too thin (worn out) or bent using a runout gage? If not, measure them. I have seen a great many cases of rotors being replaced because they "feel" warped but when measured they are in spec and the problem is elsewhere. Sometimes is just an uneven buildup of brake material on the rotor.

Just a thought...

 

Thanks for the info, it was something I didn't think about.

I just assumed that since I get some warping up front when braking at slower speeds, that it has to be the rotors. Its a very significant distraction, to the point of anything under 15mph and its an on/off type feel with the rotor as it spins, with the off being no brake pad contact with the rotor, for half a revolution.

I have inspected the rotors and appear clean and free of any crap.

 

I have to agree with above. I am still running my originals on mine and am over the 196,000 km mark. The only shudder I got was on hard braking which is part tire cupping, and part stuck bobbins. I started a thread quite a while back on how to free up you bobbins that several here tried and had great results with. The only cost to you is a can of brake cleaner.

 

Thanks Randy,

I am a little in limbo land here, as I bought the bike from a Honda Dealership in Denver without riding it. According to the sales-guy it rode perfectly before they put it on a HaulBikes truck, and didn't dhow signs of brake issues.

I have yet to contact HaulBikes about this, however I am sure there will be a bunch of finger pointing both ways.

I will try cleaning the brakes....thank-you for that.

Ash.

 

Unless they tied the bike down using the rotors there's no way shipping the bike would have any effect on the rotors

 

Take a look ag that bobbin thread. Its easy and about 20 minutes of hour time. Nothing removed from the bike. Bit you need a nut, bolt and a wrench.

 

Thanks for the link Randy.

Now that I have seen the video, that makes sense, that half of the rotor could be stuck a little to one side, which would create the warp feel.

I got the bike situated earlier where I could freely spin the front wheel, and it has ALOT of drag on the pads. When I was spinning the wheel, I could hear the left side brake pad make contact for half a revolution, and then let go for the other half.

The right hand pad was dragging full time.

Took the left hand caliper completely off and spun the wheel again and the on/off sound of the pad disappeared. I just narrowed down the issue side to being the left side.

Next I wanted to take the right side off, and realized its a different animal and could not actually get the caliper off. It would not clear the wheel when the bolts were removed. there must be a trick to this side I am not aware of.

From here I spun the wheel eyeing up the left rotor (bad side) with something stationary, so I could see if it was wobbling or not, and I did detect a slight wobble. It was not much...however there was movement to one side for 1/2 of a revolution.

So either

A. The rotor is actually warped.
B. The bobbin pins need a cleaning to free up the rotor.

Here are some pics of my front setup. Am I doomed? Anything out of the ordinary here?

Hey Randy,

When you performed this on your bike, besides wearing gloves, did you do anything special to protect your wheel finish (paint) from getting brake cleaner on them? Or was it more of a spray and quickly wipe, and then clean wheels afterwards?

Does it eat paint?

 

Nothing. Brake cleaner is not like brake fluid which will destroy your paint for sure. Brake cleaner evaporates extremely fast. That said. It would be silly not to give everything a good cleaning afterwards just in case.

 

Update.

Randy should now be known on VFRWorld as Mr Bobbin.

Cleaned the bobbin pins, and brake warping at slow speeds seems to have been reduced by 80-90%!

Testing was difficult as I didn't get to ride at speed, however there was a massive difference. Pretty quick job.

Thanks Randy!

 

Wished I could.take credit but it was that guy on the video with the wierd accent eh. But happy it helped.
