CB750 Font brake question

[78cb750-2]

Hi I'm redoing the front brake pads on my CB750 and have a question.

Do I need to glue the pads in place or just place them there. According to a local shop I just have to place them there without glue. But in my mind that would cause them not to retract when the piston retracts. When I took the break apart I found a red silicone glue holding the pad to the piston.

If anyone has any information I would most appreciate it.

Thanks,
Alin

   I have a master cylinder rebuild kit for my 75 and I'll be doing my pads one of these days too. I'll look in my manual tonight and let you know what I find if you haven't found out by tomorrow.

No glue in that area, just some grease on certain spot. If you send me your email, I can scan and email the instructions in my Clymer book. There should be slight pressure on the pads and they should not be loose in the caliper.     Paul

Yes please send it to [e-mail].

So in actuality the pads are always in contact with the disc, weather the breaks are engaged or not?

Thanks so much for this info.

  There is usually no more than an air gap between the rotor and pads when the brake is not pulled. The fluid from the master cylinder is forced to the caliper squeezing the pads to the rotor when you pull the lever. This is why you sometimes hear disk brakes squeek. If the pads are loose, you have a problem or air in the system. I'll email the breakdown to you.

Under no circumstances should any adhesive glues be used on any brake pads !!!. The pads will move back on their own once you release the brake lever. Are you sure its not a red anti squeel grease that was used that has now gone hard? I have been through two sets of front brake pads and all I did was remove the old pads and just put the new ones in and rode off into the sunset. Absolutely no need to glue brake pads onto the calipers. Dangerous!!!

Great, thanks for the heads up. This isn't something to messup on, it being a matter of life and death and all.

You betcha ! Brakes are probably the most neglected items on a car and bike, but periodic inspection of the front disc pad is a ten second job, and easy to replace. Pull the old pads out and then push the pistons back all the way in so that the new pads slide in. A word of caution - make sure that the master cylinder hasnt been topped up during the process at any stage , otherwise you will have brake fluid getting onto the paint on the tank and the frame. If master cylinder is full, suggest you drain about 1/4 of the fluid out so that when you put the new pads in, the master cylinder will be once again full.
