Hi Eric, Thanks for your prompt reply. My old ABS modulator was burned and so I exchanged with this one which is a used modulator that bought on ebay. After installing it, I found there was brake fluid leaking and I figured out the leaking was from the ABS reservoir cap. I changed a new cap but still having leaking. Some people told me to bleed the ABS (which I didn’t bleed the ABS when changing the modulator) that should fix the problem. I bought the special T-wrench but I can’t find the bleeder and that is why I looking the help from you. I think I have to buy a new one.
