Rear self adjusting brakes

Had a manually adjusted vw once. Would go too long between adjustments so I got used to double pumping the brake pedal to get brakes to stop the POS.

Fix the issue no bandaids.

Check that the area the shoe rides on, on the backing plate is not carved out in a pattern from decades of use, had a 65 Mustang with eratic braking till we repaired the backing plates.
