Was just there.

This is the classic symptom of a dead/dying PA. The brake pads give
the brake chime and the auto-check display of a brake drum/shoe.

However, this symptom is also sometimes caused by low pentosin in
the steering fluid reservoir. Check the level and refill if needed.
This was my problem last week. $5 of pentosin beats $350 of PA.
