So I'm doing my front brake discs and pands, and the caliper piston leaked brake fluid. Does this mean there's a good chance air got introduced into the system? Should I bleed that one brake line?

 

the piston should NOT leak fluid at all. What were you using to push the piston back in? Did you take the top of your brake fluid resivourie?

 

I was using a c-clamp but the piston was extended a lot.

EDIT: My bad, didn't see that it was coming from the piston.

So did you have a soft pedal before this happened, or anything else signaling air leaking into the lines?

 

hmmm... i would just put it back together and bleed that one line. Take it around the block and check it. Then check it tomorrow and then a few days after to make sure it okay.

Ive never seen one like from around the piston. Just keep an eye on it and your fluid level. Good luck.

No symptoms of anything. I was just doing a regular brake job. I think I'll just bleed that one line just in case.

 

from what you said that doesnt sound good. are you sure that it came from the piston? if that happened that could mean the seal around the pistion is bad.

but to answer your question i would go ahead and bleed the breaks.

 

if you clean off the area, bleed the breaks and take it around the block a few times, then check it, if the piston is leaking, it should be visable.

 

FYI when you push the piston in you should losen the bleeder screw so you dont push drity fluid back up into the system. This is ESPECIALLY important if you have ABS.
If it leaked fluid, something is probably fed up. I say probably.

I kind of already pushed the piston back in without loosening the bleeder screw. I don't have ABS, so I should be okay?

A 2nd question is what are the symptoms of having air in the lines?

 

I have never opened the bleeder screw when doing a brake job. You will be fine in that respect. I worked at a honda dealer under another guy for about a year and never had any problems.

With air in the lines, you would probably get a soft pedal, and will 'use' the other breaks more then the one with air in the line. Car might pull to one side or the other while braking, and uneven wear.

 

If your leaking fluid around the piston your seal is shot and it's time for a new caliper.

When theres air in the line your pedal will be squishy, soft.

Usually you cant stop if you have air in your lines. Its never a good thing. You should bleed your system anyway since your unsure. If your unsure on how to do it take it to a shop.

 

Well I was just out breaking in the new brakes & rotors and nothing seemed out of the ordinary, other than the smell of the brake breaking in. Does it seem like everything should be okay?
