Exclamation Front brake fail.

While riding this past weekend, I discovered my front brake failed completely and I needed to re apply quickly to get it to work on four different occasions. I suspect it might air in the master as it was replaced recently. My mechanic says it might be something else. Any Ideas?? I'm not feeling like riding until I can fix it .I have an 07 deluxe

Check the fluid level in the master cylinder.
Also, there could be air in the line if it pumps up and works.

Find another mechanic while your at it. What he should be saying is I will come and get it and I promise you this will not happen again. I would think very hard about letting a paid mechanic work on it again if he errored on brakes unless it was a new part that failed beyond his control.

Your mechanic thinks its something else? Did he even help you troubleshoot? I can think of a few things I would check and I'm not close to being a mechanic. Sounds like you should find another mechanic.

You meant...."Mechanic Failure", in your heading.
I do All my own work, and have never been disappointed.

Our brakes aren't terribly complicated, but can be intimidating b/c of the whole death thing if you get it wrong. Basically:

Does it have brake fluid on the inside? That's good.
Does it have brake fluid on the outside? That's bad.

Does it have air on the inside? That's bad.
Does it have air on the outside? That's good.

As was said: this mechanic should sell his tools. I've NEVER heard somebody say "my brakes failed" without me saying "holy **** man, let's fix that". I'd find somebody else to wrench on your bike if you're not inclined to do it yourself.

Thanks for your posts. Looks like I will be doing my own work. I will bleed them and see how things go.

If you think there may be some air, just take the cover off the master and put it back on loose. Then just tie down your brake handle so it is compressed about half way and leave it overnight. Any air that was in it should burp out into the reservoir.

Make sure you don't have a warped disk. One rotation pushes the pads back. They will pump up while stopped but brake is lost as soon as you move. Weird but I've seen this happen.

And that would point right back to the mechanic also. If he needed to replace a master cyl,it would be nice to know why.
