    The panic button has been hit (brakes binding)

    Well, my trip is booked, tunnel, hotels and all the other stuff. Going on the 6th June to Norway.
    I replaced my front pads for some EBC HH sintered jobs. I did that last week but only road it Yesterday. The front brakes are binding.
    All I did was gently push the pistons back, fitted the pads and hay presto, I've bagged it up .

    I striped one calliper to check the condition of the components. All spotlessly clean and corrosion free, as is the whole bike. 11k miles, 3 years old. No problem before fitting new pads.

    1. Master cylinder is sending up a jet of fluid (when little baffle plate removed).
    2. I clamped the hose near the one removed caliper and it bled ok after .
    3. Rear brake seems fine.
    4. Confirmed correct pads fitted, only one set listed for 1200x.

    If I can't get this sorted, my trips off. I've managed to get it looked at, at my local Honda dealer but only for a one hour slot on Friday, not sure if they will sort it in that time.

    Any ideas ? Could it be the valve half way along the system ?

    How bad are your brakes binding?  How many rotations will your front wheel do when you spin it by hand?

    I changed my front pads a few months ago and they were binding a little and my method was exactly the same as yours.

    Checked everything and couldn't find any problems and so left them and kept an eye on them.  After riding a little the pads bedded in better and the binding reduced.  2,000 miles later and a tour of Ireland and all is well and no concerns.

    Like me I expect you are worried about nothing.

    Hi Kingsonr
    Just been out and checked the rotation & I'm getting half a turn. I'm going to take the bike out again tomorrow after work and see if it starts to bind when hot again.
    Never had this with any other pad changes. And yes, I'm  a bit worried due to the mileage in going to be doing. If the dealer says all's well, I can stop panicking  :047:

    Half a turn isn't great. Is there too much brake fluid in the system preventing the pads retracting from the disc after the brake lever is released?

    I am sure it is a straight forward fix and you will soon be enjoying your tour. I would love a tour to Norway.

    I could smell the brakes when I stopped, thought it was the car in front. I'll ride tonight and see if it's  better post re-bleed.

    taking the reservoir cap off. Sometimes the fluid is topped up with worn pads... when new pads are fitted there is not enough space in the reservoir to take up the displaced fluid.Another thing that sometimes happens is the bellows in the reservoir cant move far enough, Taking the reservoir cap off allows the bellows to take it's shape again.

    Just a thought. Are the new pads fractionally thicker than new OE Honda pads would be? It would only need to be a fraction of a mm thicker to cause dragging on the discs. If the pistons are fully recessed yet there still isn't enough space to leave a tiny clearance, hey presto, dragging brakes. I rarely buy anything other than genuine parts because of situations such as this. I would suggest fitting Honda pads on Friday, small price to pay if it saves you calling off your trip!

    All good points fella's.  Going for another ride in an hour. I do remember a buzzing noise from the area below the tank. Got loader as i accelerated,  but couldn't hear it at speed or stationery (oops, forgot to mention that). It didn't do that before the pad change. ABS pump maybe ?
