GM Genuine Parts 22895243 Brake Master Cylinder Cap

Works as intended.

I bought this to replace the DOT3 cap on a 2022 Tesla Model S Plaid after upgrading to Carbon Ceramic Brakes with DOT 5.1 fluid from the service center. They don't swap out the cap. Since they don't make DOT 5.1 caps, I opted for a DOT 4 cap. This fit perfectly without any leaks.

Item fitted as it should.

Works perfect for 2018 Camaro ZL1 1LE. I replaced the stock fluid with DOT 4 for track use and wanted to make sure the cap stated the correct fluid.

Perfect replacement for 2016 Chevy SS

Perfect fit for my H2

Fit 2016 REGAL

I was under the impression that this cap would work on my car but it does not tighten down.
