98-01 Disk Brakes,

so my front disk brakes are warped on my 2001 vfr, only noticable when coming to a stop (they seem to grab, then let go, grab and let go)
anyone have ideas as far as a nice and decent aftermarket option?
looked on ebay, but nothing really grabs me..
thanks,

Greg

 

I like the play on words, "nothing really grabs me"!

As far as rotors, I would stay with stockers as they generally hold up well and are cheaper than most aftermarket items. I was just looking that galfer stuff and it was in the $650 a set range.

Oh yes, I would want to know why the rotors warped, perhaps you have a sticky caliper that should be rebuilt prior to installing a new set of rotors or the new ones will warp in no time at all.

 

Stockers were 430$ each (before tax) in Canada when I had to change one of mine. Got a lightly used pair of Galfer waves for 400$ on eBay.

 

Wow that is some serious coin!

They are $250 a piece from Ron Ayers

You should do a run out check on them to see if one or both are warped as you may only need the one disc.

 

Even if the $ exchange rate is almost on par, we still pay a prime in Can compared to US for Japan imported parts. Same for European gear (Sidi, Alpine Stars, Puma, etc).

 

Mine came with a set that look just like these.

I have no complaints. They grab great, haven't caused fading even when I rode a bit hard and haven't warped.

thanks for the replies guys.
I bought the bike second hand from a fellow that did not consider maintenance important. I flushed the system completely with a vacuum bleeder.
I did buy some aftermarket pads (EBC)to replace the worn stock pads, and initially thought it maybe a pad compound issue.
I did clean the rotors off, with 350-400 grit sand paper.
Is there a easy way to check run out(not sure if it's the right term) on the disks? someone suggested to take the rear caliper off, to check if it's causing the grabbiness, again not sure if im going in the right direction.
The lurching is most noticable below 30 KM/h when slowing down, otherwise no issues.

I believe that a warped rotor would be felt at any speed. Is there a pulsing in the brake lever too or just in the way the bike slows?

To check the run out of the rotor, you need a dial indicator and a mounting base of some sort to secure it. Many bases are magnetic so that wont work on the front fork legs as the are non ferrous material which means you need a clamping base of some kind. Do you have any buddies that do automotive or aircraft work as they will have access to the tools to do this job. I guess bike tech may have them too.

This is a bad example but in this picture I'm using a dial indicator with a base to measure the wear of a valve guide in an Audi V6. Yu would use the same or similar tools mounted on the fork leg to measure the run out or "wobble" in your rotors. Of course the rotors may only warp when hot so thi scan be tricky.

 

kind of totally unrelated how our minds have biases that prevents clear thinking.
Few yrs ego I was shoveling snow and my back just froze in odd position bent to my left.Pain was intense.My wife said I should see a chiropractic (not a real science)
Needless to say he just run away from me.My mistake was trying to diagnose my condition on line.Huge mistake! From disk rapture,nerve damage,torn muscles etc.I had them all so I thought.
Finally went to see a doctor and after the tests he concluded that I had severe back muscle tension which prevented me standing straight or move at all.I was much relived however it took 2 months of physical therapy to recover.

Now why I shared this story.The biases in our minds.Once we make an assumption sometimes its hard to overcome.
I suspect your disks are not warped.Chances are your pads need replacement.

 

thanks for the suggestions, as I mentioned, the pads are brand new EBC pads.
i'll check for warpage tonight.
The bike does not pulse, it only feels grabby at low speeds, allmost lurching to a stop..
It's slightly annyoing, something I can live with, as I got into the habit of slowing down with the transmission, and matching revs etc...
only using the brakes coming to a complete stop.
again appreciate all the feed back, and the nice pics
