Master Cylinder and Brake Booster

Well last week my brake light was coming on while driving. Pulled over and found the brake fluid was low. I did brakes about 10k miles ago and thought maybe i didnt correct the level. So i set the level to max. the next morning the brake light was on again. Brake fluid level at min. checked and found no visable leaks. I was suspecting that the master cylinder was leaking internally into the brake booster. So i didnt drive it to work. I checked with toyota and ordered a master cylinder. Part came in and when i went to install it the part did not fit. I returned the part and after a big headache the part was packaged wrong so we ordered another one and i decided to replace the booster also due to the large amount of brake fluid in the booster... Well about 805 dollars later in parts my truck i up and running again.... My trunk is an 05 with 90k on it.... keep an eye on your brake fluid level.....

 

My Taco 2003 was with the same issue, I notice the Brake light and i go to the mechanic, and the brake fluid was leaking into the booster, and already ordered a new booster
I expect it to fix the issue
