Akebono problem:/

6mtg37s · 12-06-2010, 01:31 AM

So the drive was spirited and I end up with a whole lot of scratches on the disc (not too worried since they will go away by time) but what worried me is the little brake fluid that came out of the caliper. It was a little fluid(which made my caliper change color) from the bolt located on the top covered by the rubber. I don't know whether to take it to the dealer or just add some fluid and drive on. Any suggestions?

One more thing, it doesn't leak or anything anymore but the pedal does feel a little softer.

Check the brake fluid level, and if it doesn't feel right? take it in, and have it checked, Just to be on the safe side.

Im scared that they might go off on me for driving it hard hahaaa, I'm gonna add some fluid tomorrow. I hope the caliper isn't destroyed.

I think it's crazy how companies make sports cars that are meant to be driven hard and give you features taht make it perform better yet it'll void warranty or is simply not covered.

wasn't the launch control feature on the r35 GTR an example of this?

They can't tell you that, and you aren't obligated to tell them the circumstances. Besides, there are members who beat on these Akebonos all the time both on and off the track and have not had these issues.

6mtg37s · 12-06-2010, 02:22 AM

hm, I'll let my service manager take a look at it tomorrow, hopefully warranty might cover it.

That is the bleeder screw. You either have a defective bleeder screw or it isn't tightened correctly. If it let fluid out then it is also likely that it let air in, contributing to your spongy pedal feel.

spearfish25 · 12-06-2010, 07:44 AM

I had two calipers leak some fluid from the bleeder screw during a track day (white residue trail down the caliper from the screw). Given that the pedal stayed solid, we concluded that some residual brake fluid sitting in the bleeder nipple boiled off (the opening is upward so it can hold a few mls).

It sounds like you boiled your fluid. Either you had some fluid in the bleeder screw top that also boiled off, or your bleeder screws need a little tightening. A 10mm wrench makes it an easy job, but you'll have to pull the wheel to get at the inside bleeder screw (two on each caliper).

If the pedal is spongy, you'll still need to bleed your brakes though.

kenchan · 12-06-2010, 11:20 AM

also make sure you bleed both sides per caliper...

Mike · 12-06-2010, 12:01 PM

you definitely want to bleed them.

I get that all the time at the track, especially the brake intensive track that I go to. My theory is that the heat expands the caliper just enough to allow some fluid to escape around the bleed screw, as I have tightened and tightened mine as tight as they will go, and it only happens on the track.

6mtg37s · 12-06-2010, 10:04 PM

So if I bleed them should I stick to stock fluid? Or is it okay to mix the stock with for example ATE Super Blue? Or any other fluid better than stock.

AP Racing Formula 5.1 is ideal for street and high-performance use. It has the ideal viscosity for ABS systems. Plus, it does not contain dyes that the "blue" fluids use to permanently stain the reservoir with.

I think I am going to pick up your fluid from Stillen over xmas break for my brake overhaul next year.

These don't come in 1L cans though right?
