caliper leak

[2kool]

2013 ford edge, while freeing up park brake cable on driver side rear  I noticed I have a small leak coming from behind parking brake linkage at caliper. if I tighten that linkage nut a bit , appears leak slows but I think it still has an ever so slight leak. is there a seal behind there that can be replaced or should I just replace that caliper? thank you.

A leaking caliper is dangerous. Speaking just for myself, I would never rebuild a caliper. (I knew a guy years ago that rebuilt one and it blew out 6 months later and caused a minor accidient). If it were me, I'd bite the bullet & replace the caliper. (And I'd go Motorcraft if available). Leaking brake fluid is always  dangerous.

Thanks for responding. Appears it has stopped leaking but I am checking it daily. If I see any ever so slight leak, I am going to replace it.  This is a rebuild with about 30k miles on it. but I had to get rough with a maul to free that sticking cable up.

Thanks guys,  leak is from back side of piston, where park brake linkage mounts.  I am going to replace the caliper.

if feasible, use a motorcraft branded replacement.  rebuilt/remanned by other brands may not perform at the same level, however flawed OEM may be.

 

also service brakes regularly, including slide pins, boots, and fluid.

yes, and thanks for advice. I do maintain the pins etc.... i got a little over zealous trying to work that park cable free and caused that leak. Most of the time, the motorcraft branded parts are out of my budget. That being said, I am a big fan of FORD and also a ford retiree. Thanks again replacement parts scheduled for delivery Friday.

I have basically a similar issue. Rear left caliper is leaking (as confirmed by the dealer today). The brake goes basically to the floor, but car will still stop. If it's pumped one or 2 times, the pressure temporarily comes back for about a second, then back to the floor. I'm not driving it and left at the dealership.

 

My question is, what determines when the brake light indicator goes on? I would think with a fluid leak (or even when I needed the brake booster replaced), that a light on the dash would appear alerting there's a brake issue? The only time the brake light is ever on is when I use the emergency brake in the driveway when it's parked.

 

I have a 2012 Edge limited with approx 154k on it.

 

Thx.

I ?think? the light is triggered when the reservoir gets low on fluid. Peddle going to floor is usually a leaking master cylinder.
