Castrol DOT4 Brake Fluid

[AUSMHLY]

It seems Castrol has discontinued making/selling DOT 4 brake fluid. I called Castrol and was told they discontinued it in July 2021.
I was thinking if I could find it I would stock up. I asked what the self life was for an unopened aluminum sealed bottle was. He said 3 years.
I asked if they have a replacement, answer is no.

What other brand is recommended for our British cars now?

Any DOT 4 brake fluid. They are all compatible and must meet the DOT standard.

The reason they have discontinued it is Fidel died.

Just don't use silicone. It's more compressible, the last thing you need in the AH brake system.

I've been using DOT 5 in my brake and clutch systems for over 20 years. I started with completely new systems, Other than having to do that, the disadvantages of using silicone have, IMO, have been overrated.

You must be late to the party. Auto-correct had changed it to Castro brake fluid.
