Leak from left landing gear

[BradB]

Any thoughts on what this fluid is?

My Acclaim has been sitting in the hanger for the last week.   I noticed this under a drain that comes out near the gear door on the left side.   Does anyone know what fluid this is?   A problem?   

Thanks for looking.

Hydraulic fluid from the brake caliper.

Color is kinda brownish...indicating old brake fluid...I agree ,fluid appears to be dripping from caliper bleeder nipple in photo...maybe it was struck by an object and is now leaking..or debris under caliper piston o rings...

Have your mechanic rebuild that brake caliper at the least ,and than bleed new fluid to both calipers...how has your braking been?

Looks like you need a new o-ring in your brake caliper. It is an easy job to replace the "o"-ring and bleed the breaks when finished.

Thanks for the replies!   Just pulled my mechanic over to look.  Needs a new o ring.  We checked and added hydraulic fluid.   He is checking to see if he has the parts to fix now.  

 

The braking has has never changed.  I never thought that it had the best brakes in the world,  but there has been no difference.   

Will share all the responses with the mechanic. I appreciate it.   It was much easier to stop in and see him when I could say that I had some hydraulic fluid leaking.   He came right over with what he needed.

When the fluid begins to break down from heat from the caliper it turns brown tha become gummy...after replacing caliper o ring ,bleeding new fluid can improve braking ...I agree I have the same brakes on my Bravo...and they are so so

It might be Hangar Elf urine.

Maybe it was just that @piloto was the last one parked there.

Real ironic. I went to my hangar today after not having been there for a few days. Same exact leak. Going to see Joe Cole on Friday. Does anybody have the part number for the O ring?

Braking power should be enough to lock up the mains.  Probably takes fresh fluid to do it though...

You will find the fluid reservoir in a pretty convenient place on the LB, compared to all the other Mooneys.

Now would be a great time to do a well controlled drain and replacement of the fluid.

You might have air in the system already, based on the pee puddle you have.  If this is the case, your hangar elf will probably use a pressure pot to fill the system from the brake end, forcing fluid back toward the reservoir... 

PP musings only, not a mechanic...

Thanks.  I agree, I'll have him drain and replace the fluid when I get the o-ring replaced next week.

I'll be back out at the airport tomorrow.   I'll try to hunt down the mechanic and ask, he should have it somewhere convienent after looking today.

The 5606 brake fluid in the long bodies turn thick and dark after a few years of use. I would suggest periodically changing the fluid at annual to help keep all the components in top shape. You can eliminate the oxidation and such with high temp brake fluid such as Royco 782, which Spruce carries. It is 100% compatible with 5606, but has much higher flash point, is synthetic, so won't break down like 5606 does. It is mil spec approved, so no issue with approvals. Bleed from the caliper up using a pump or pressure pot.
