Got a 94 montero sr with no to little to no brakes. I just bought it, the previous owner just said that they stopped working. The abs light had been on for a while. I filled with brake fluid and did get very small amount of braking. I have been all under the vehicle and found no leaks. No leaks around the master cylinder. I did notice what looks to be like a leak from the bottom of the abs modular (on the passenger side front fender well). Can they be rebuilt, common gasket leak? something loose? replace? Throw away no more abs? Any suggestions? Thanks
