Review on ACDelco Professional 18M1878 Brake Master Cylinder Assembly: Efficient Solution for Superior Braking Performance by Rick Rownd

Revainrating 5 out of 5

Worked great on a 1973 K5 Blazer

I believe the truck's original master cylinder was stuck and leaking at the back of the block. I bought this, installed it in a truck, bled the block and then the individual brakes. I don't remember the brakes on this truck ever working so well, except maybe when my dad bought it brand new in 1973, but I've only had the chance to drive it for the last 20 years.

Pros
  • Weight
Cons
  • Crumpled
