While I was on a road racing track couple of weeks ago, I noticed that brake fluid is seeping out the the thread on the bleeder of the front brembo... but I didn't felt any change in the paddle pressure. I then went on to tighten up the bleeder a little, but I still see fluid seeping out after the next session. At the end of the day, I clean up the calipers (did not tighten the bleeder anymore) and drove home. After a few days, of street driving, I don't see any fluid seeping out. My question is that is this nornmal? Should I put some teflon tape on the thread on the bleeder? If so, will the temp be a problem for the teflon tape, don't want a stuck bleeder. Btw, I am using ate super blue.

Thx,

From the sound of it, you didn't tighten the bleeder properly after flushing the ATE into the brake system. I wouldn't recommend using teflon on the threads, they (threads) don't seal the fluid out anyhow.

If your problem reoccurs or becomes persistant I would go to the dealer, brakes are not a system to have malfunctioning.

 

kekek, thx for the reply.

I think the bleeder was tightened to spec, but it still leaks... I went on a even tighten it a little more... I was thinking if it has to do with the differences in the rate of expension on the steel bleeder and the aluminum calipers... this only happens at the track, i have a laser pyrometer, the temp on the caliper is around 300 degree C.


I think i will stay away from teflon tape.... any more suggestions.

 

Might be some residual fluid left over inside the bleeder from when you bleed the brakes. The fluid got hot and bubbled out. Next time you bleed your brakes, hit the bleeders with some brake clean, or a rag and some compressed air (dont blow the brake fluid all over!) to get the left over stuff out. If you really have a problem, it wouldn't take long before all your fluid was gone, and the pedal at the floor.
