Fitted my Chinese brake rotors and....

[The Buddha]

I am so sorry I didn't read and understand the original post.

K brake lever pulsating and shuddering while people say its warpage in the rotor, it actually is a thick or thin spot in the rotor. Its a manufacturing defect.
However that matters little, the fix is still to get a replacement.

Cool.

Well the replacement rotor showed up today - fitted it up as soon as I got home and took it for a ride to bed the pads in...

The disc is perfect - no warpage like last time - and the slotting is very agressive and feels bitey on the pads. I'm am sure the pads will wear out faster with these rotors but hey, if it stops better then I'm happy to compromise a little!

To the seller's credit, they sorted out the mess with no fuss and in minimal time. They accepted my complaint and never asked for the dud to be sent back - just sent me a new one to keep me happy... and I am

Sweet! I just installed a chinese rear rotor yesterday and it's a big improvement over the horribly scored rotor that it replaced. The brake feel is much smoother and easier to control! I am so far very satisfied with it.

rear rotor I removed that from my gs the day I got never made sense to have since I never used it. sheds a lot of weight. I only used the front braks and never had an issue stoping on time. so wasting money on rear brakes are a bunch of hoopblah. morons

Well, I'll admit to rarely using my drum rear brakes on my old Hondas but the GS500 rear disc is a different matter.  I wouldn't leave home without one.  I always say my GS500s have dual discs, one on the front and one on the rear and both equally important.  That rear disc can be your best friend when you get into a corner much too fast.  Doubt you'll ever match the minimum stopping distance possible during an emergency stop with a front brake only that comes even close to a stop made using both together properly.

So was this photo taken on the day you got the bike?



Maybe you should work on your spelling, punctuation and grammar before you go calling people morons  
Your insights on the uselessness of a rear brake are amazing mate - I wonder how every motorcycle manufacturer didn't work this out earlier?

Woot I am a moron because I use a rear brake 

or maybe he meant mormon, with that spelling how do you guess?

Crazy people abound... what'll that save ya?  2.5 pounds for everything (including the caliper)?

Aya, cause stopping in a shorter distance than front brake alone is highly overrated, don't you know.

I hope you never encounter stop and go traffic in a slope.

Not that its relevant, but it's weight shaved from the rotating mass. Same as drilling speed holes in a steel sprocket, 520 chain conversions, lightened crankshafts, smaller tires, etc.

It is bothering me that you can't say c@%t, f%$k or shaZam! on this forum, but you can give all sorts of advice that's going to get people hurt.  There's people saying that you should never use the rear brake ever and you should actually remove it, and then there are those saying that you shouldn't be making emergency stops on the front brake because if you lock it you'll wash out the front and drop, so avoid the front brake kids.  Combine this with the number of morons on the internet who don't even understand the physics of how a motorcycle turns who nonetheless dispense advice on cornering and a self taught motorcyclist with access to the internet becomes a pretty dangerous proposition.

Whilst it's true that the front brake's the one for stopping the bike quickly in a straight line, you need both brakes, you need to be taught how and when to apply each one, and you need to consciously practice using both in a variety of circumstances.  Correct use of the clutch and rear brake is key to all your slow speed manoeuvring, and you're going to be another rider who inexplicably drops bikes in carparks and petrol stations until you get it properly susssed out.  Or you'll spend a lot of time awkwardly duckwalking your bike around cos you can't control it slower than walking pace.  You want to save weight on your bike? remove the 150lbs of moron perched on top until you figure out how to ride.

You may want to sometimes gently trail a little rear brake if you've overcooked a corner, emphasis on the gently, preferably without easing off the throttle.  I'll let you off since I assume you come from some boring part of the world that doesn't actually have any corners.  Obviously it's preferable to just lean in harder and keep rolling on, but some days you just run out of balls.

Honda had it sorted a generation ago, although it didn't really survive the translation.

5. Go soothingly on the grease mud, as there lurks the
skid demon! Press the brake foot as you roll around
the corners, and save the collapse and tie up.
