  • What adhesive to use for brake pads?

    One of my neighbors is thinking of using the yezdi brake pads(which are riveted) cut into smaller strips and pasted onto his bike and weed whacker as it will save a lot of money compared to buying new. However when gluing it to the shoe using araldite/feviqik etc it comes off after a while, probably because of the heat. Googling "brake pad adhesive" gives me a bunch of links but since I am a noob when it comes to bikes I am not able to figure if the purpose of those is what I outlined.

    Is there some special adhesive to use to replace worn out brake pads with new ones? What brand and where can I buy the same?

    A photo to clarify my query;

    Do not opt for a money-saving option when it comes to a critical component such as brakes. It is the matter of life and death.

    query approved.

      Brake pads reach hundreds of degrees within a fraction of second, this immense heat and pressure asks for High temperature adhesive. And a tube of such glue will be way over the cost of a new brakeshoe! You need to look out for Silicone glue paste.
      Note: The cost to fix is more than getting an new and better brake pad which I highly recommend!

      There are no short-cuts to any place worth going. So ride safe when you are treading uncharted roads.

        2 part metal epoxy adhesive like the JB Weld is what will serve your needs, but it being expensive, defeats the purpose of saving on brake pads. It will cost at least Rs.800-1000 landed in India, which means probably buying new brake pads will be the same.

        It works perfectly though, provided one knows exactly how to mix and use them. I always carry one set as part of my emergency bike repair kit while touring.

        Silicone adhesive is not meant for metal to metal bonding, though I concur that getting a new brake pad is best alternative.

          thanks for the responses I will tell them to look for 2 part epoxy adhesives and see if there are any local brands in the market. How about Aralidite Steel Epoxy?

          If the metal epoxy adhesive is so expensive/not available locally then what are the brake pads glued with by the companies that sell them? My neighborks also use them in weed whackers in which case the rate of wear is much more than in bikes and so buying new brake pads every month or so is also problem. What they are doing now is to use some ordinary adhesive and use it for a few hours and then glue it again when it comes loose because of heat/wear.

            Not sure about Araldite Steel epoxy, haven't tried them.

            If your neighbour is using ordinary quickfix cement to keep the brake pads together knowing they will come loose, I would say he has no value for his own life and others. It is extremely dangerous to do so.

            Factory supplied brake pads also use industrial adhesives which are tested extensively. I doubt it is going to be easily available over the counter.

              +Million times!!!

              Why do a copy paste work when things are available over the counter. If the braking needs to be improved I see 2 simple solutions...
              1. Learn how to brake effectively
              2. Switch over to hydraulic disc brakes

              And, talking on the financial part, disc brakes are even cheaper on long terms compared to internally expanding ones

                I agree with your point 100%. But to clarify, currently they are doing that on the weed whackers only fwict where the danger is limited to damage to equipment (though if it were successful they'd probably use it on their bikes as well considering how money minded they are).

                  JB Weld is the same two-part(resin+hardener) epoxy adhesive as araldite , yamapoxy or fevitite . JB Weld also makes a two-part epoxy putty (same as m-seal) . The usage of the word "liquid-steel" in the product is purely for marketing, they call their tube of the epoxy resin that . Hopefully you are not importing it for that price !

                    First, don't do this. Don't chop up a brake pad and glue it to the brake internals. You're just asking to die at that point.

                    Second, this will not save money, since as noted, the only adhesive that could work in this situation is something like JBWeld. The problem is that, once the glued-on brake pad material is worn down enough to stop working properly, you'll have to replace not just the pads, but the rest of the brake internals too. Once it's set, JBWeld does *not* come off.
