Does the brake proportioning valve on a 2001 subaru make 1 rear hang up?
No, the brake proportioning valve on a 2001 Subaru does not cause one rear brake to hang up. The brake proportioning valve is designed to distribute brake fluid pressure equally between the front and rear brakes, ensuring that the vehicle stops evenly and safely. If one rear brake is hanging up, it is more likely due to a problem with the brake caliper, brake line, or master cylinder.
