If the brake power assist does not function --
The power assist to the brakes functions only when the engine is running. When the car is moving
without the engine running the brake pedal pressure required to stop the car is increased 3- 4 times.
The brake pedal feels stiff and hard.
Disc brake noise: A slight-to-moderate amount of disc brake "squeal" is considered normal.
Air dam (front spoiler)
A non-factory air dam can negatively influence the normal flow of cooling air to the front wheel brakes.
(See section titled "Wheels and Tires").
If one of the brake circuits should malfunction the red warning light will come on
(See section titled "Warning Lights".)
The pedal stroke increases slightly and the pedal feels softer but the pedal pressure required does not
increase noticeably.
If the light comes on while driving and the brake pedal can be depressed further than normal, it is an
indication that one of the brake circuits is not functioning. Stop immediately, open engine hood and
check brake fluid level.
Reservoir empty: do NOT drive. Tow car to shop for check/repair of brake system. Reservoir not empty:
proceed immediately and with caution to a Volvo dealer for an inspection of the brake system.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or hilly areas. The speed is usually
low which means that the cooling of the brake is less efficient than when driving on level roads.
To reduce the strain on the brakes it is advisable not to use the brakes excessively.
Instead, shift into a lower gear and let the engine help with the braking. A good rule is to use the same
gear downhill as would be used ascending the same grade. For vehicles with automatic transmission use
position 2, or in some cases, 1.
