Review on πŸ”§ Dorman M39500 New Brake Master Cylinder: Superior Performance and Durability for Optimal Braking by Brett Jarvis

Revainrating 1 out of 5

Took two years and 3000 miles, steer clear of this junk and buy a quality part instead

I installed this on my 87 Toyota pickup two years ago and replaced my original Toyota master cylinder. I've driven the truck almost exactly 3000 miles since installing this MC and recently I've noticed that the seals are starting to leak and the pedal is starting to sag when I'm sitting on the headlights. The Toyota MC lasted 130,000 miles from 1987 to 2015. Doorman MC, 2015-2017, 3,000km. I'd be better off just buying a rebuild kit for my OEM but I'm too lazy. Now you will definitely regret it. I'm going to look for an OEM at a junkyard and do what I should have done from the start as I foolishly threw away my OEM after installing this junk on my truck.

Pros
  • Hands free operation
Cons
  • Very expensive
