Foot brake

업데이트됨 7/23/2018

The foot brake is used to reduce the car's speed while driving.

The car is equipped with two brake circuits. If a brake circuit is damaged then the brake pedal will engage deeper and a higher pressure on the pedal is needed to produce the normal braking effect.

The driver's brake pedal pressure is assisted by a brake servo.

경고

The brake servo only works when the engine is running.

If the foot brake is used when the engine is switched off then the pedal will feel stiff and a higher pedal pressure must be used to brake the car.

For cars with the Hill start assist (HSA)* function, the pedal returns more slowly than usual to normal position if the car is parked on a gradient or on an uneven surface.

In very hilly terrain or when driving with a heavy load the brakes can be relieved by using engine braking. Engine braking is most efficiently used if the same gear is used downhill as up.

For more general information on heavy loads on the car, see Engine oil - adverse driving conditions.

Braking on wet roads

When driving for a long time in heavy rain without braking, the braking effect may be delayed slightly when next using the brakes. This may also be the case after a car wash. It is then necessary to depress the brake harder. For this reason, maintain a greater distance to the traffic ahead.

Brake the car firmly after driving on wet roads and after a car wash. The brake discs are then warmed up, dry more quickly and are protected against corrosion. Take the prevailing traffic situation into account when braking.

Braking on salted roads

When driving on salted roads a layer of salt may form on the brake discs and brake linings. This may extend braking distance. For this reason, keep an extra large safety distance to the vehicle ahead. Also make sure of the following:

  • Brake occasionally to remove any layer of salt. Make sure that other road users are not put at risk by the braking.
  • Gently depress the brake pedal when driving is finished and before the next journey starts.

Maintenance

To keep the car as safe and reliable as possible, follow the Volvo service intervals as specified in the Service and Warranty Booklet.

New and replacement brake linings and brake discs only provide optimal brake performance after a few hundred kilometres after "wearing-in". Compensate for the reduced brake performance by depressing the brake pedal harder. Volvo recommends only fitting brake linings that are approved for your Volvo.

중요

The wear on the brake system's components must be checked regularly.

Contact a workshop for information about the procedure or engage a workshop to carry out the inspection - an authorised Volvo workshop is recommended.

Symbols and messages

Symbol

Specification

Constant glow – Check the brake fluid level. If the level is low, fill with brake fluid and check for the cause of the brake fluid loss.

Constant glow for 2 seconds when the engine is started - automatic function check.

경고

If and illuminate at the same time, there may be a fault in the brake system.

If the level in the brake fluid reservoir is normal at this stage, drive carefully to the nearest workshop and have the brake system checked - an authorised Volvo workshop is recommended.

If the brake fluid is below the MIN level in the brake fluid reservoir, do not drive further before topping up the brake fluid.

The reason for the loss of brake fluid must be investigated.
