Going over my brakes this evening I noticed a tiny bit of seepage from the lower inboard port that comes plugged. I've heard about them seeping reading on here. Is it as simple as removing the plug, re-sealing, and re-installing?

yes with some locktite which will also act as a sealer. Probably 2 different metals heat cycle to loosen it and allow seepage.

I had the same problem with both my SL6 calipers the first event I used them. Just took an allen wrench and tightened them another 3/4 turn till snug. One side was much looser than the other. Never leaked since in 2+ years use.

Loctite? Not "regular" white thread sealant? That's what I was told use use on the NPT adapter that threads into the caliper body for the brake hose to connect. Just wanted to verify as my brakes aren't something where I want to learn by mistake the first go around

I think it was your post that I read. If it's a NPT fitting then tightening it will push the taper in further and fix it. If it's not NPT then it'll need new sealant.

Last weeknd's race was extremely hard on the brakes

You need to run a race at CMP with no yellows the entire race... Road Atlanta is easy on the brakes compared to there

When I had those calipers I had the same problem. Just tightened it and had no more seepage.

Thanks guys... will just tighten it and let it ride.

Exactly! Suffered the same problem here. I had to purge the ABS unit too in order to get the air out that was allowed into the system while tracking. Wilwood's QA on this part of the assembly sux! Causes a lot of inconvenience for no good reason!

Not sure how air would get into the ABS from there. Wouldn't it migrate upward toward the bleeder?

SouthernSon

Beats me. In any case, the air was in there until I tightened the plugs and purged it. The whole dang brake system seems to defy my understanding of any logic. It is truly a magical, mystical, obstinate and frustrating product of some engineer's idea of a practical joke.

Couldn't leave well enough alone. As I tightened the fittings I could see that it was most definitely tread sealant used on them. Decided to just re-do both to b e 100% done with it. Used high temp thread sealant rated to 400 degrees vs. loctite.

Anyone know why those need to be there in the first place?

Thread sealant would be the correct application.

These extra ports are installed for some racing applications where the actual side inlet is not accessible for use. It's pretty much exclusive to the BSL6 Narrow Outer Body model "for Wide Five" applications so I'd suspect that's the main culprit.

They are never fully seated when shipped as the supplier doesn't know what port you'll be using is all.

Good to know... I'm going to go ahead and re-do the other side as well. Can't win the car show if the thread sealant doesn't match from side to side on the inboard side of your calipers

And you didn't fit any light weight aluminum blue ones? Points deducted for you!


Q on the model info; from what I know of the body shell halves this is good info. If I find differently I'll correct it.

Mine are from a LG G-stop kit which uses the asymmetrical calipers. They're narrower on the outer 1/2 for wheel clearance, but still take the 20mm 7420 pad.

Those are the ones. And believe the only ones with the pesky alternate holes.
