[i3randon12]

be4 paying a guy to put on the front caplier and bleed it, what are so ways i can find out it needs to be rebuilt or if it is in good condition,      i bought a used one, and want to know be4 have it put on!!

please help

I don't know of any tests other than hooking it up and seeing if it works. I would try to do the job yourself. Brakes are pretty easy to work on.

[newbieone]

It would be to much trouble to bench it. Just hook it up and take it for a spin but be extremely careful.  Make sure that rear brake is in check.

Man....DON'T PAY someone to do either.

Mounting and bleeing are dead simple and reasonably quick, that's why bikes are so much fun. The only thing to rebuild are the seals, and they are probably fine, like everyone said, test it ...easy. You will see in your driveway after bleeding if there's any real leak. Apply as much hand pressure as you can to the brake and just hold it there. For like 30 sec. Did your lever move? No....Then there's probably nothing wrong with your brake.  Need a walk through? email me, I'll step you through it, but don't pay someone man.

Cheers.

Like JohNLA said, you would pretty much need to attach the brake hose and bleed the brake yourself just to find out (for sure) if the mechanic will be able to do it.

But if you DO ... make sure you put something between the pads!  (Preferably the front brake rotor, with the caliper mounted in its usual place.)

==================

Not to bring up a painful subject, but you said you stripped the threads for the bleeder valve on your original caliper.  Would you mind giving a little more detail?  Did you just crank on it too hard or something?  I'm curious about what actually happened there....

If you are all thumbs... and have paid someone to do it... the very least I'll do is replace the fluid that's in there with Dot 5. Its blue, silicone based and doesn't take on water or eat paint. That's it. Its very easy otherwise.
Cool.

WELL I HAVE NO CLUE HOW I CAME TO STRIP THE INSIDE,      I WAS GETTING REALLY FUSTRATED WITH IT,   YOU MIGHT REMEBER HELPING ME ( I SQUESSED THE BRAKE AND COULDNT GET PISTONS OPEN,   THE GUY SAID HELL PUT ON THE CAPLIER AND BLEED IT FOR 25 DOLLARS,       I MUCH RATHER THT THEN RISKING IT DOING MY SELF

Huh?!!! Are you serious? Brake systems designed for glycol based brake fluid (DOT 3, DOT 4, DOT 5.1) should not be filled with silicone based brake fluids (DOT 5) and vice versa. At least that's what everybody says. The rubbers used for gaskets and seals are a different type and are attaked by the wrong brake fluid.

[Turkina]

I've heard about the same.  DOT 5 brake fluid requires a rebuild of the brake system.  After that, you really don't have to worry about the brakes anymore.  The whole system has to be completely flushed of the old fluid.

[The Buddha]

Flushed yes, rebuild no... You cannot mix petroleum based dot 1 through 4 and dot 5.1 (synthetic petro type) with silicone based. So you need to get rid of all the dot 4, then fill and bleed with dot 5. Used in my GS since 97, for 25K+ miles, and used in many more bikes for years. I have had to bleed it and change fluid etc, In fact I dont even mix brands. I was using some auto store stuff, now I have belray... yea its more $$$ but that bluish purple color is so cool, and much more visible through the sight glass... Its a better brake fluid, and if you are bleeding it anyway might as well go with stuff that stays shelf stable and lasts longer and looks cooler and works better and doesn't eat paint... It wont cause the seals to die, dont worry, in fact the vacuum bleeding pump's use silicone based fluids as a lubricant, so I am sure the brakes internals will also work better. I have never used brake kleen or anythign like that so no idea how that will react with Dot 5. Dot 5.1 (a favorite among harleys) is synthetic 4. Total BS. Its just as bad as dot 4.
Cool.
