Help needed I replaced all 3 sets of pads on my 2002 ABSII STeed and while front brakes are behaving perfectly the rear brakes for some reason are dragging against the disc big time. I have bled the system as per manual 3 times over the last 3 days still no improvement all ideas would be appreciated even the idea I had of a stick of dynamite up the exhauST. This is a major PITA as bike is my daily ride and would like to sort it asap.
Thanks in advance for any assistance. Paul :H : :cuss :H :cuss :H :cuss

Check the operation of the secondary master cylinder which is located above the LH front calliper.
Centre pot of each calliper is operated directly by the foot pedal.
Hand lever operates the front calliper outer pots directly.
Any braking on the front wheel (by foot or hand) causes the LH calliper to operate the secondary master cylinder which then applies the outer two callipers on the rear wheel.
-
the foot brake is operating all three pistons on the rear.

If you're not moving then foot only operates the centre on the rear.
1100 Brake system; this is how it is set up.

so why is mine being so impossible and doing what it's not suppose to would that indicate a rear caliper overhaul asbike was on centre stand and I pumped foot pedal a few times after putting new pads in.
-
Possibly rear master as well.......may not be allowing fluid to return.
I leave callipers mounted and just remove and replace the pads (they slide out/in) when I do mine.

that was how I did mine

but that would also effect the front as well........
Possible causes from manual

You may have a pad thats sitting a bit skewed. I would suggest removing the read pads and ensure that the pistons are full compressed before refitting. While out, check for proper wear. ie pads are wearing in a parallel manner.
-
While you are checking the pad alignment as Brock suggests, You could check that all the shims and spacers are correctly installed, especially part 17 in the foto below. It is easy to install this upside down or wrong way around.
-
17 looks like what the Army mechanics called the anti rattle clip. It is spring steel to stop the pads rattling in the holder. Also if missing can cause pads to squeel.

Thanks everyone for your help it's got me beat I have decided to take it of the road and let my mechanic suss it out.
