Just a thought....how much would a slightly dragging rear brake affect my overall fuel economy?
I ride a vfr750 and my average is about 34mpg,which isnt that great to be honest.I do have a fairly fuel-consuming riding style however im not changing that anytime soon .
My brake has a sticky piston which i just havent got round to sorting out.when i get back from a ride,the disc is hot enough to touch for a second or two before it starts hurting-it doesnt bind up though.
I wouldent complain with that mpg. I used to get less than 30mpg on my gixxer6. If your a bit throttle heavy then its not going to be economic.
As for the binding disc.. I would get it sorted a.s.a.p. I had a binding disc on one of my older bikes and it eventually cracked from the heat. Expensive!
hmmm, 34 mpg, that's a bit low. I've had 2 VFR750's & never got any lower than 42mpg....even on a trackday!!!
I'd certainly get the caliper sorted, it doesn't take much to do either.
If that doesn't improve your mpg & assuming that the rest of the bike is in good order, then I'm afraid to be a bit blunt you need to look at your riding style.
I wouldnt worry about your mpg its inconsequential. Get your bike sorted, binding brakes are not safe - leave it and eventually it will fail completely and that could be a locked rear wheel if your unlucky.
Personally I wouldnt ride a bike with a binding brake.

I rode my last bike,an aprilia pegaso 650,for 9 months with a knackered master cylinder.i only used the rear brake in emergencies and then had to stop and let it unstick itself/cool it down/ring the fire brigade!
I think i probably will get off my arse and sort it out this weekend...
Also,MPG does matter when youve got about £30 to last you the rest of the month for food and petrol!

Careful application of Copperslip on the piston should do the trick but it means caliper off and a good clean 1st if done properly, might have rust, poo & spiders in there!

Apparently coppaslip isnt good for the rubber seals..i normally use silicone rubber grease stuff.
I know what the problem is;when i overhauled the caliper i didnt clean one of the seal grooves enough,so when i put it all back together with fresh seals it still stuck a bit.....and then i couldnt be arsed to drain it,disassemble,clean etc....

Well done, would you like a medal, what if a kid stepped out infront of you? etc etc?
If anyone saw my van I drive, they think its a shed, but mechanically its sound, and I would never drive anything less, and I certinatly wouldnt ride a bike with any known problems, its asking for trouble.

Dont get me wrong-i wasnt bragging about it!The brake actually worked fine everytime when operated,like i say i just had to let settle again afterwards s it didnt overheat.
If the brake didnt stop the bike then theres no way id even contemplate riding it!
