We have the cure for that one. It’s only free if you get the work done that we tell you it needs. If you are just in messing around, you will pay. Nice try, Marshy. Ian

How much is some? If it’s from normal pad/show wear then it shouldn’t drop much at all and it should be over a greater length of time. It would be far more noticeable of a drop if you’re losing fluid.
Response:
oil on rear brake pads I have noticed that the brake pads on the right rear side of my 1992 GMC 1/2 ton 4X4 have been saturated with either brake fluid or oil. I am preparing to replace the pads and will replace the cylinders at the same time. I am wondering if the source of the contamination could be from a leaking axle seal as opposed to a leaking brake cylinder. (a question) Is there any easy way to tell the difference? BTW, this has been this way for months, and there is no oil spray visible on the wheel. This fact leads me to believe the source is most likely to be brake fluid. Any insight would be greatly appreciated. Dennis answer to your question….. taste it…and make it a fair sampling….. if it seems to numb your tounge and makes your jaws lock up ..like you just ate a pecan and left the bitter stuff in it……. it’s Brake fluid. if you tasted a fair sampling…. and need a second helping to be sure it’s not brake fluid… it’s Gear oil. carry it to a qualified repair shop for a FREE diagnosis and repair quote….they’ll give you some more insight…and likely even a free paper floor mat. ……. HaroldLoyd thinks everyone ought to take advantage of a shops "take a look at it on my rack for free" policy….. Midas.. and Meineke.. are really great resources for looking under your truck on a lift…. if only to mess with em….LMAO.

Brake fluid is bitter as all hell, motor oil has a rather pleasant Doc – Hide quoted text — Show quoted text -> I have noticed that the brake pads on the right rear side of my 1992 > GMC 1/2 ton 4X4 have been saturated with either brake fluid or oil.

Yes, some. But I have also lose some of the transaxle oil over time as well, so its kind of hard to tell.
Response:
Exactly! If it stinks, it’s probably gear oil. I had a driver’s side axle seal go bad on my ‘02 2500HD at around 10K miles. It’s been a while since I’ve smelt that having newer trucks . . . . smelled enough at that time to last a while as well! It will also probably be smoking after you get done driving. Has the brake fluid level dropped off in the reservoir? Later
