Brake Fuild Leaking

Hey guys,

I noticed brake fluid coming out between the master cylinder and it's 'booster pack' behind it. It's all over the 'booster pack' plastic and runs down under the car before dripping off. Anyone seen this problem before? It's not a massively fast leak, something I hadnt noticed until today when my fluid level was low for no apparent reason.

I dont seem to notice extreme brake fade and can't make fluid come out under pressure... I don't have much experience with master cylinders and dont know if it's a simply seal or easy fix?

Anyone had this problem before?

Cheers in advance.

what your describing sounds like you need to replace brake master cylinder seal, grab the R32 GTR service PDF off the net it will show you step by step how to do it..

master cylinder seals usually don't go on their own, usually means you've got air or dirt in your brake lines, or you've mixed 2 fluids together which werent compatible when topping it up in the past

Bought a new seal kit from nissan, when mine was leaking more than usual. They wear out from age too.

Check the bore when you pull the old assy out to check for scoring, damage etc, clean with new brake fluid and use a brake rubber grease if you have some, on the new part before you refitt. Then go a full brake and abs bleed.

Mine stopped leaking after that, and I also cleaned, primed and resprayed the areas where the brake fluid leaked onto/under when I was rebuilding my engine (easy access).

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
