8.8 caliper keeps leaking??? help wanted.

[green93]

ok, so the other day I smell something from back right wheel. I stop look and there is brake fluid all over the inside of my wheel/tire, but i still have brake pressure. so i go to parts store and buy a brand new caliper for the rear and pads etc, bleed them. Everything works perfect. The next day, puddle of brake fluid on the inside of my wheel and once again i have brake pressure. what the problem here guys?? Any info will be helpful.

I'd check to see if it's leaking from the banjo washer.

Its not leaking anywhere around the line..it leaking from the inside of the caliper like where the pads are. Is the banjo washer the brass washers that are used with connecting the line to the caliper?

:yup:

Bummer about what appears to be an internal leak coming from the caliper itself. :(

Not my pic - but does it look something like this?

thats wierd... probally your diff cover seal is bad or maybe it has something to do with the axle breather hose...but i doubt that.

the axle seal is going out. they are on both sides of the carrier

Well.....yes and no. :agree: / :disagree: I agree that the axle seal is probably what is causing the leak - but they are not close to the 8.8 carrier!

The 8.8 axle seals are at the ends of the axle tubes, next to the flang & outboard of the outer axle shaft bearings (shown here on mine). :) This way, the outer bearings also get lubricated from the differential oil.

Sounds like you need a new seal. They are not hard to get to & I can give you info on that if needed.
