Brake help
So the left rear brake on my 1970 cutlass keeps locking up like if I pull up to a stop sign that one brake grabs hard enough to make it feel like you’re gonna go through the windshield anyone know what would be causing this it’s just going forward haven’t had a problem when in reverse

Most commonly it's often the parking brake is set too tight. In particular, if you just performed a recent brake job you just need to ensure the parking brake is not set too tight when changing out rear brake components; albeit, the reason my asking about the brake job and parking brake. The CSM describes how to adjust the rear drums - I believe they self-adjust by running in reverse several times. Ensure the anti-rattle spring is not compressed.
Here's a link, but the CSM is your best authority.

Most commonly as stated above there is/was a leaking wheel cylinder and the shoes are contaminated with brake fluid. Another clue would be a low master cylinder. Pull the wheel and drum off and take a look.

I’d be in with the brake fluid idea except brakes do work in reverse and forward. They lock up moving forward but not in reverse. If it were brake fluid they should lock up in reverse also. My bet is mechanical.
