How does the brake system work in a Ford Sierra?

A pressure regulating valve is incorporated in the rear hydraulic circuit to maintain the desired pressure ratio between the front and rear circuits.

How to diagnose hard brake pedal master power brakes?

A) With the engine not running, press and depress the brake pedal several times to remove any vacuum from inside the booster.

Why did Goodyear Flush my soft brake pedal?

Took it to goodyear over Thanksgiving weekend (everyone else was closed) and they flushed it with little progress made (maybe a little higher).

Is there such a thing as a soft brake pedal?

But then it was a super soft pedal. took it around the block, slammed on the brakes a few times and managed to get them to lock up a bit (trying to clear air from the ABS). Then got another almost quart through, and thought some air out (hard to tell doing it alone), but still soft.
