Hey I was hanging out under my dash the other day wiring in some new toys and noticed a thin small leak on my firewall that is coming from the back side of my brake pedal. Any tips? Is this something that a lot of people are running into or just me? Thanks for the help. P.S. not sure if this helps but I currently have no issues with braking. Thanks again.

Its your "HYDRA-BOOST" put your hand under the booster, right were it connects to the brake fluid reservoir, there should be fluid leaking its the seal, and also runs throught the seal from the rod, major problems w/these.

I tried to get one through napa...autozone...ect, and they said that they cant get them, its a factory order item. around $550-600 rebuilt through gm. I went to the junk yard found a 05 dmax, $75 and no problems, Installed it my self, to save even more money, its a P.I.T.A, but can be done.
