Locked Brake Pads

Postby twaggoner » Tue Oct 09, 2012 4:39 pm



I have been looking over the posts for brakes and did not find one to specifically address what I am doing so... here it goes. In bleeding my brakes I have discovered that on both front calipers, the pads are locked, tight, on the rotars. I have removed the brake line, from the caliper, on one side to see that the pads did not release. Up to this point I have the bike on the jack stand and am ready to remove the front tire but, the question is... "what is the best way to get the pads to release from the rotars? "

I hope that I have explained this well enough and I would greatly appreciate any advise that you Wingers could give. Thanks!!!

open the bleeder and you will have to pry the pads back.

you will be spraying/spilling brake fluid, so be aware. A small hose put on the bleeder,then into a jar, would help.

If removing the brake line from the caliper didn't release the pads, then opening the bleeder isn't going to make any difference - any pressure that was in there holding the pads in place would have been released when the brake line was removed. In this case, it would appear that the pistons are seized in place.

Were the brakes locked on BEFORE you bled them?

No... I have replaced my front tire and did not have any trouble removing it. However, since purchasing the bike at the first of the year, this is my first attempt at fully bleeding the front lines. Honestly, and I am ashamed to say this. I primarily downshifted and used my rear brake what little I was able to ride it this summer. So, for all I know, since I have owned the bike this is the first time that fluid has been forced completely through the lines.
What can I do to free the pistons? That is what I was fearing has happened. Again, I greatly appreciate all of the advice.

if the pistons are stuck you have to push them in a little to get the calipers off. then the task of rebuilding them can begain. A pry bar might move them just enough to get the calipers off.

I'd look on BikeBandit.com or any of the other vendors recommended here. I'm being told to stay away from Sabre as they're reputation is in question. There's stuff I'd buy on eBay and stuff I'd be leery about. Unless you know someone that has bought rebuild kits from a particular eBay seller, I'd stay with parts from a recommended merchant, if not Honda genuine.

I can completely understand the temptation to lay off the front brakes, but it is not a safe way to ride if you do it as routine. Remember that you're riding a heavier bike and the laws of kinetic energy apply, "An object in motion tends to stay in motion until acted upon by a greater force". The greater force being either the brakes or an immovable object. You're putting way too much trust in one wheel braking it sounds like and I'm afraid that one day by no blatant fault of your own, you may pay a price for that, potentially a very stiff price. When I took motor officer training, one of the maneuvers we were taught was high speed braking. This was taught by starting at a complete stop, accelerating as fast as you could go, then when the instructor waved his hand you had to stop as quickly as possible without skidding either tire and you had to get the bike stopped right near where he was standing so you had a maximum stopping distance to contend with. The only way this could be done is with using a lot of front brake, but not enough to lose braking control and dumping the bike. By using just the engine and rear brake, you're extending your stopping distance and in an emergency situation, if you do this way too routinely, you'll tend to become a creature of habit and won't get the bike stopped in time. I don't want to see that happen to you or anyone.

Thanks for the good advice on the parts AND the wisdom in your riding experience. I will practice more patience so I do not get myself wrapped an unforgiving object!

To all that responded... Thank you for all of your advice. I tore down, totally, the callipers and the pistons were in need of attention! I am happy to say that my first total rebuild was a success. I rode in this morning and it was GREAT to be back on the road! Thanks to all again!!!

That's what we are here for. Were you able to get ALL the air bled out of the system? Some have had trouble with this. (me included, till I discovered the secret)

DUDE!!! This being my first ride in... the brake handle seemed to have a little more travel than what I would like but the calipers seemed to pump up fine.
So... What is the "Secret"... ya gotta get me in the "Down Low"!!!

Easy, when you think you have them bled, then bleed one more spot. Crack the banjo fitting loose and bleed the air right at the master cylinder. That finally did it for my GL1000.
Nothing else would work , not even clamping the lever over night.

Sounds good! I will have to give a shot if the lever does will not operate properly.

Sometimes cranking the handlebars over one way or the other will help get that last air bubble out of the caliper or master cylinder line as well.
