IAPATHFINDER Posted December 9, 2010 Share Posted December 9, 2010 hello, new to the forum. my pathfinder usually just sits in driveway, its my wifes winter ride. today i noticed there was fluid on the tire. reached under to check out what it was, it smelled kinda oily. could the cv boot be leaking?? or maybe just really dirty break fluid?? noticed it was a little low. asked the wife if the pedal felt funny and you can imagine the reply i got. "it doesn't feel like my convertible" which has 20000 miles and 11 years newer. anybody ever seen this issue. i had it apart 2 years ago to replace ball joints and tie rods, but never leaked since then truck has 165000 miles on it and has been rarely taken off road any help is appreciated Link to comment Share on other sites More sharing options...
ahardb0dy Posted December 9, 2010 Share Posted December 9, 2010 where on the tire? Inside? was it on top and running down the tire? or did it look like it was splashed all over? If a CV boot ripped the grease can turn into a thinner liquid. Which tire Pass or drivers side? Link to comment Share on other sites More sharing options...

ahardb0dy Posted December 9, 2010 Share Posted December 9, 2010 Well on the driver side you have brake fluid and clutch reservoir if you have a manual trans that is. Link to comment Share on other sites More sharing options...
IAPATHFINDER Posted December 9, 2010 Author Share Posted December 9, 2010 Well on the driver side you have brake fluid and clutch reservoir if you have a manual trans that is. its a auto trans, there was a small pool on the lip of the rim that felt and smelled like brake fluid, but what was on the tire smelled like oil or grease, its strange looked dry around the master cylinder Link to comment Share on other sites More sharing options...
sewebster Posted December 9, 2010 Share Posted December 9, 2010 Is the caliper covered in brake fluid? Pads? Link to comment Share on other sites More sharing options...
IAPATHFINDER Posted December 9, 2010 Author Share Posted December 9, 2010 Is the caliper covered in brake fluid? Pads? it didnt look like it, but i will be pulling the wheel off today. was mostly contained to the bottom part of the tire where it contacts the pavement Link to comment Share on other sites More sharing options...

unccpathfinder Posted December 10, 2010 Share Posted December 10, 2010 I'd guess power steering gear... Link to comment Share on other sites More sharing options...

IAPATHFINDER Posted December 10, 2010 Author Share Posted December 10, 2010 Neighbor's cat?? Yeah, just pull the tire and take a look... B LOL it was a bad seal on the caliper piston. the caliper was soaked w/brake fluid, what stumped me was the oily smell, but i think that was from over filling my upper ball joint w/grease. thanks for all the suggestions. these trucks are good ole trucks and im impressed at the reliability. this is the third nissan i have owned, 2 of the 3 were good vehicles i will remember how helpful this forum is Link to comment Share on other sites More sharing options...
Precise1 Posted December 10, 2010 Share Posted December 10, 2010 Ok, I figured it was something hard to see with the tire on. Did you rebuild or replace it?? Reason being, you want to clean and grease the slide pins too if you rebuilt it. We try to help, sometimes it works... B Link to comment Share on other sites More sharing options...
Chriskaw440 Posted December 11, 2010 Share Posted December 11, 2010 I was kinda hoping it was the cat.... Link to comment Share on other sites More sharing options...
nunya Posted December 11, 2010 Share Posted December 11, 2010 isn't the power steering pump and reservoir on the pass side? Steering box aint... looks as though this problem got solved before i popped in so i will add my $.02 to the mix. Since you found it to be a caliper, I suggest making both sides on the same level (rebuild/replace both) brakes ain't something you wanna forget and regret...

I never thought of this, but it does make sense. after all it does have 160k on it, we have owned since 120k, and the prev owner never said anything about changing it, when i go back to work i will ask him. good advice.
