I bled my brakes yesterday and after i put it back together and drove it, I noticed like 6-8 drops of brake fluid dripping from the bleeder valve. I tightened up those valves and its not leaking anymore. my question is can air get into the lines with such a small leak? should i bleed it again? The brakes still feel solid.
If i had help standing by i would have just bled it already but i dont, so i want to make sure its necessary before i bug my friend again.
thanks


Also i noticed that each time i put the protective rubber caps on the bleeder valves the pressure from putting the caps on caused them to leak a tiny bit of fluid through the threads of the valve. so i left them off. I torqued the bleeder valve to like 28 lb ft (i'm afraid to go any tighter stock torque specs are 7 lb ft ), and it doesn't leak when i hit the brakes. I guess i'm just curious if anyone else has observed this before, how does that valve work and why would putting external pressure on this valve cause a leak?

 

I would probably bleed that caliper again just to be on the safe side. However I wouldn't expect you to have introduced air into the system.

Also, why did you torque the bleeder valves down to 28ft-lb if the spec only says 7?

 

The reason i tightened the bleeder valve so much was so when i put the rubber caps on it wouldn't leak, which didnt help. I knew it was way too much.
I'll bleed it again
thanks for the reply

 

I've experienced the leaking while running the rubber caps. I felt as though the ring that goes around the threads prevents the nipple from seating properly. I've taken them off with no ill effects. As you have found.

I'm pretty sure the valve works by sealing the valve against the caliper body. If this were overtightened multiple times, depending on the caliper material, if could possibly distort and lead to more leaks. Another reason to follow the torque specs...
