Raybestos MC34404 Professional Grade Brake and Clutch Master Cylinder Assembly

Fit perfect on my 1963 Chevy c10

It fits and works good

Exactly the same unit as was on my 60 year old truck, and functions perfectly, thanks.

Worked perfectly for my 1964 GMC medium duty dump truck with the brake & clutch being together, Exact replacement.

Solid, and identical to the old one it's replacing. Only hiccup is the clutch side cylinder returns slowly (3-4 seconds instead of 1 second on the other one) during the bench bleed... hopefully no big deal.

I bought this for my Dad's 1962 Chevy. It was defective and had to be returned. Hopefully the second one from Amazon is better. We'll see in a couple days. The first one had a problem with the brake side piston. When attempting to bleed the master cylinder per the instructions, the brake side cylinder would get stuck and not return properly. The clutch side piston was fine.

Still a great unit.Same master cylinder that's been in use for over 60 years.

Little sticky on the clutch side but still works
