Help!!!!

Just washed the bike and the rear brake has seized. Done nothing else since a longish uneventful ride yesterday.
 Any suggestions as to the cause and, hopefully a possible solution will be greatly appreciated

Cheers
Troy

Abe:
What year is your bike Troy?

When was the brake pads and brake fluid last changed?

troy_s:
Hi Abe
2006, brakes look fine and fluid not changed since i purchased ( this may be a sign that i have been a bit slack)

 Thing is that i literally rolled the bike about 5 meters to outside the garage - didnt even start it, washed it, tried to put it back to discover the locked wheel. Since the first post it has unlocked itself after indeperssed the rear pedal a couple of times.

 Happy to accept that it is a one off but dont really want to find out otherwise - particually at 110kph. The odd part for me is that it was only the rear brake that was affected given that both brakes opefate all the time to differing degrees.

Cheers
Troy

I'd be looking at possible issues with the secondary master cylinder which is located above the LH front calliper. It's a mechanical link so quite possible that the  master got stuck and didn't release pressure on the rear calliper. Maybe a bit of lube on the SMC link system might help.

Picture is of your brake system and will give you an idea of how it works. This is the ABS version but the basic 1300 works the same way but remove the modulators and ECU (???)

Hi guys,
I thought I make note of this here has I have just been experiencing a similar issue after replacing the rear brake pads.

I replaced the rear brake pads with new Metal Gear ones and after using the rear brake for the first time my rear wheel wasn't spinning freely anymore.

With the bike on the centre stand I could spin the wheel by hand however as soon as I let go it would stop almost instantly.

I took the bike for a run thinking that maybe I just needed to bed in the pads but when I got back the disc was sizzling hot and the issue remained.

I did a lot of reading and diagnostics before  I figured out the issue.

When I had replaced the standard Honda pads with Metal Gear pads I had reinstalled the metal plate that sits at the back of the standard Honda brake pads to the back of the new pads.

Anyway after removing this metal plate from back of both pads the brakes now operate normally, stopping the wheel from moving and then releasing allowing the wheel to spin freely.

So if you are doing a brake pad change DON'T reinstall the metal plates pictured below.

Cheers
Shiney
