Akebono problem:/
 

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.

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.

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.

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.

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

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?

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.

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.

If you boiled the stock fluid this time, it will happen again if you just use the OEM fluid again. I plan on using Motul RBF600 which is overkill but I find piece of mind knowing I will never have to worry about boiling the fluid ever, it is a popular choice here with great results.

Thats i dont want the factory fluid, its such crap. Im thinking about the ate tho.

SuperBlue works fine for me. I would flush the factory stuff out with it rather than topping up though.

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.

Yea I just dont want to touch the rears tho, how many liters do we need again? I've done every brake job except this haha

You'll have to do the rears if you want to get all the air out won't you? :)

I think we used a can and a half flushing/bleeding mine.

You can get away with 1L if you are careful with the bleeding. Best to have 2L and be generous.

If you are going to change fluid you will need to bleed all 4 corners. Go in order of distance from the master cylinder, the rears will take more bleed time than the fronts as there is more fluid in the lines. Right rear, left rear, right front, left front. Bleed the outside of the caliper followed by the inside of the caliper.

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

Two 500mL bottles = 1 Liter.

We recommend either Endless brake fluid or the Motul RBF600.
If you're able to come out to our dealership, I'm sure our dealership can help you out.
I don't know what the issue is that you had with the fluid slightly seeping out of the bleeder cap/screw, but that's never a good thing, I would have it looked at asap. could be something faulty. IF it's all OEM, it might be something easily covered under warranty, but again, that all depends.
you can call us at 800-989-6173 (my extension is 2287) with any questions. We are a very mod friendly dealership ;)
