So i change out everything on the brake system except the booster.
After a short drive the brakes start locking up. It happens sometimes ast but sometimes with a few miles.
I stop release the front bleeding nipples and go again.
What could be the issue?

Welcome to 2carpros.com

Did you replace the rubber brake lines to the caliper. They can collapse internally and cause this to happen. Also, has anyone replaced the brake light switch recently? Also, the push-rod from the brake booster is adjustable. If that isn't properly adjusted, it can keep a small amount of pressure on the brakes. Keep in mind, as brake fluid gets hot, it expands. So in theory, the hotter the brakes get, the more expansion in the fluid and the more pressure applied to the brakes.

I attached a pic of the hose I am referring to. Let me know if that was done and if this is a problem that existed originally.
