I found it when I took the right rear tire off to find out why the brake were grabbing. It appears that its coming from a large hole in the hub. It doesnt have the look or smell of gear oil. Is it possible that its brake fluid? Doesnt look like the wheel clynder is leaking tho the brakes wouldnt return and grabbed alot and the wheel cyl wouldnt adjust. If it is a axle leak do I have to tear down the axle to fix it? I was planning to put the ring and pinion gear set that patricks sells in down the road.
Thanks | | |

Whatever is leaking dries fairly fast and leaves a slight stain. The right rear brake is shot, gummy crude all over the pads and the hub. I know I cant clean the pads but what can i clean the hub with?
Thanks | | |

If what you have is evaporating quickly, I'd suspect rusty water, blood 8-), or something weird. What does the other wheel look like? Are you low on brake fluid?
Cheers!

Comparing it to the fluid in the master cylinder might work except that the fluid there might be a different color/brand.

If that doesn't answer the question, have someone pump the brakes while you are watching the wheel in question.
Good luck! | | |
