Review on Raybestos MC391138 Professional Master Cylinder by Johnny Mcnealy

Great price, quality and fast shipping. Works great on our 2009 Toyota Highlander. It's good that it's new, not renovated. It even includes a guide plate/shim template that you insert into the brake booster to ensure the actuator rod is properly adjusted. This is very important if you are also replacing the brake booster. I had to replace the brake booster because the old master cylinder leaked out of the rear seal and filled the booster with 17 ounces of brake fluid. The stem of the new brake booster was not adjusted correctly for my new master cylinder. Using the included plate as a guide I was able to adjust the bar adjuster to the correct depth. It is very important! I highly recommend this master cylinder. The only thing you might want to get is a slave cylinder bleed kit for a few bucks to make the job of blowing air a little easier.
