Updated: Nice replacement OEM

I installed this in my 08 Ram Mega Cab 5.7 and so far so good. 3 days after I installed this someone pulled me right in front of me and I had to hit the brakes. It stopped quickly and smoothly as expected without jamming. My old master cylinder could only brake soft to medium, anything hard would lock the rear wheels. This fixed the issue and I'll let you know if anything changes. When changing I used Prestone brake fluid. One thing I noticed when bleeding the bench was that one of the fittings

Pros
  • Master Cylinder
Cons
  • Safety
