I have a 2004 Hoe, I thought the master cylinder was going bad because i had a leak right where it joins the hydro booster. Well i have a new master cylinder now, but still have the same leak. Now Im guessing its the hydro booster itself. Does anyone know if they can be rebuilt or do you just need to buy a new one? The fluid thats leaking is reddish, (power steering color) So i believe it is that... but not sure because it is much clearer than it was before i changed the master cylinder... then the fluid was darker...like old brake fluid. But still the same leak, from the same joint. there appears to be a channel at the bottom of the hydro booster where the master cylinder couples together with it. does this act like a "weep hole" as a water pump would have?? thanks in advance
