What is involved in changing my rear break pad? Do I need to remove the tire or can it be done with it still on. My crankcase exhaust has been leaking really badly and it saturated the rear break. I have given the bike a little rest until I fix it. I plan on making a little catch for the exhaust and cleaning the whole thing up, but I would like to replace the pad on the brake. Thanks.

The wheel must be removed to switch out the pads. I've found that the best way to do this is to jack up the rear end and disconnect the shocks so the axle may be removed below the mufflers. Then unplug the electrics and remove the rear fender. This makes the wheel easy to remove and replace. Remember to clean all the brake components carefully and not gunk up the surface of the new pads. Chances are good that you'll need to use a c-clamp to compress the caliper pistons into a fully open position to make room for the new, wider pads. Wipe down your axle with some grease before reinstalling and use NeverSeize on the threads. Wipe down the surface of the disc with alcohol to assure that no residual oil/grease is on it before trying to seat the pads.

I didn't find that you needed to remove the fender off a Thruxton to remove the wheel.. The Bonnie has a larger fender.

sorry got to disagree.change my pads on the rear never removed the wheel never dropped the shocks.
loosen(do not remove) pad retaining pins
undo caliper mounting bolts.caliper is now off rotor(hose still attached DO NOT REMOVE)
take out pad retaining pins
remove pads
replace with new.
carefully force pads apart
replace caliper carefully tighten all bolts to torque
DOUBLE CHECK EVERTHING

agreed, no need to remove either wheel to replace pads. Just follow the directions cafecruisn gave. Now to inflate the tires, remove wheel........

Before removing the old pads, crack the bleed nipple with a rag over the end, and rock the caliper side to side to push the piston(s) back into the caliper. A small amount of brake fluid will escape. Then tighten the nipple. Clean the disc surfaces with a scotchbrite and brake cleaner, and wipe with a perfectly clean cotton cloth. Install the new pads....Then continue as recommended.

Agreed that the wheel does not have to be removed to replace the pads, but the caliper was contaminated with oil according to Mantooth's account. That means everything will require throrough cleaning...a task not possible with the wheel in place.
