Smell of burning rubber

There's also the option to upgrade all the calipers to 6-pot Pretech units. But that will set you back a few shekels.

my rear breaks will slid the wheel with a medium touch why would u want more except for looks?
 
Are there any instructions on rebuilding the caliper? I don't trust the manual anymore, I just changed the pads in less than 10 minutes per youtube video, pistons still sticking though so it looks like a rebuild or replace. They are ABS brakes so I know I'll have to buy the bleeding tool, this is just another job I've never done before so some instructions would be great if they're out there.
 
I'm arriving a bit late here so just to clarify, you're having trouble with your rear end and you are getting an over powering smell of burning rubber when you're riding. Not that there is anything wrong with that

It might be worth checking your master cylinder seals, you could try cracking the brake line at the master cylinder and if the slave piston releases from a locked on position its likely a problem with master cylinder piston seals.
 
That sounds reasonable enough to try. Will I have to bleed the line afterwards? I don't have a bleeding tool yet so what I've done is to depress the pistons with a screw driver, I can ride at least as long as I don't use the back brake. I figure when I get the bleeding tool and the Dealer Tool I'll replace the fluid and try that first. It's only got 18 km on it but it is four years old and its my understanding any moisture in the line can cause problems. It used to live on the damp west coast until this spring so I figure changing the oil is a good thing anyway. From there I'll try to rebuild the seals, I think I saw a kit for $42.
