    Rated 5 out of 5 by from JEGS Master Cylinder This is a great looking master cylinder and is lighter than the stock cast iron units. I also like that it has the option to run the brake lines on the opposite side. I bought this unit after having not much success with rebuilt cast iron units that kept leaking. Also this one was on the lower cost side of other aluminum ones I researched. The two Allen screws to retain the top give it a nice clean look and are an improvement over the bail type retainers. I had a little trouble with getting the front brake line to stop leaking but I am using silicone brake fluid which may add to the difficulty. I used some high temp thread sealer on the outside threads to resolve.

    Rated 4 out of 5 by from Booster I would like to have better finishing on the cap the chrome is a little wavy. The booster has line ports on both sides which makes it universal but the plugs are not finished which takes away from the appearance.

    Rated 4 out of 5 by from Looks nice, works well Looks great in the car and I like that you have to take the top off to add brake fluid, keeps it rom scraping the chrome like the old flip style ones. Easy to install, great for different applications
