Fluid leak help.

Yup! I'd just see if its loose, along with the hose fitting at the bottom.

 

I see no reason why you couldn't.

 

If you are low on brake fluid,check the manual which specs it should have.

 

If it is brake fluid don’t get any on the body paint. It will eat it off.
I also recommend using some brake clean or acetone type solvant with a rag and wipe the fluid off of the tire sidewall. Brake fluid will soak into the rubber and soften it and make it sticky and ruin the tire if left on too long.

 

You can tell by it’s odor. Wheel bearing oil is going to have a strong gear oil smell. The brake fluid well smell like it does when you take off the master cylinder cap.

Brake fluid will loosen up existing dirt and grease and clean things. Gear oil will not. It just adds to the mess.

With hydraulic brakes (aka juice brakes) it is entirely possible that the front wheel bearings are grease packed instead of oil filled. They can run hotter than air brakes.

 

If the leak is brake fluid...repeated pumping of the brake pedal will show a brake fluid leak.

 

I’ve got a ‘65 Ford Galaxie 500 that years ago had a leak. It took around 100 miles of city style braking to empty out the master. No indication of leak anywhere. Put fluid back in and bled back up fine. Than it would empty out slowly again. After a handful of times I
finally discovered that it was a small leak on RR slave. It would slowly bubble out when applied and just soak in to the grease and dry out from the summer heat down here I guess. It was weird for sure. Never felt spongy. The wheel cylinders had so much crud built up in the ends it acted like a dam. At the time it had 76,000 mi on it and it’s original 40 year old brakes. Lol!
