    Rear Brake Caliper Binding

    I`m after some advice please,

    The rear brake caliper on my CT ( a, 2012 model not DCT, @ 26,000 miles ) had its piston seals replaced 500miles ago because one of the seals began to protrude from its seat therefore, (I thought)
    the pistons were not returning causing the brake to `bind.`
    Its well documented that the brakes do bind on this model bike but my concern is that,
    Even after new seals have been fitted ( by a well established Honda main dealer )
    and,
    That the caliper / pistons etc are spotlessly clean the brake is still binding quite bad !
    I`m worried at the very least that the brake disc will `warp` or at the very worst could get so hot that it ( brake & disc) locks up !  :027:

    I am off to Scotland in 4 wks so I`d prefer to get to this sorted before I go so some advice would be much appreciated
    Thanks

    Not quite the same, but I had this problem with a VFR800 some years ago.  Problem turned out to be the rear brake master cylinder that was sticking.  Replaced it with a used item from eBay and all was well again.  Might be worth checking to see if yours is sticking.

    I suggest using TRW PFG110 for break seals and the whole caliper rebuild. Take a look at PDF. But do not touch anything pads related! For pads there is special high temperature grease made by LiquiMoly bremsen-anti-quietsch-paste! But never confuse it with anti-quietsch-paste - without word bremsen! It is very important and they have diffrenet applications!

    I had a similar problem at one stage. Turned out to be a dirty slider, the large pin the calliper slides back and forth on.

    Thanks marcopol

    I thought the same,
    so cleaned it and this time I put just a spot of lubricant ( as you do ! Ha,, ) but made no difference

    I assume you are sure it’s the brakes and not the handbrake that’s binding. You will know by the temperature of the calliper. If it is the brakes bring the bike straight back to the dealer and tell them whatever they did must has caused the problem and the Bike is too dangerous to ride.
