Immediate improved brake response

After trying this cylinder assembly, I noticed a significant improvement in my car's braking response. The installation was quick and easy which is ALWAYS a plus. The overall quality of the product is impressive and exceeded my expectations. The only downside is that it`s a bit pricier than some other options on the market. .

Pros
  • Reliable and durable cylinder assembly designed for professional use
Cons
  • More expensive than some comparable options on the market

Just buy it - the newer the better!

For this El Dorado 79-85 it is becoming increasingly difficult to find quality parts. I went through 2 master cylinders in a week! Then I got AC DELCO listed here. Everything has returned to normal. My AcDelco device was made in China (NEW). The last was a reconstructed Cardone-USA unit licking out of the bore while seated.

Pros
  • The piston assembly and return spring eliminate brake drag, which can lead to premature wear of the brake pads.
Cons
  • The list is long.
