Nissan Juke Owners Manual : Brake system
BRAKING PRECAUTIONS
The brake system has two separate hydraulic circuits. If one circuit malfunctions, you will still have braking at two wheels.
You may feel a small click and hear a sound when the brake pedal is fully depressed slowly.
This is not a malfunction and indicates that the brake assist mechanism is operating properly.
Vacuum assisted brakes
The brake booster aids braking by using engine vacuum. If the engine stops, you can stop the vehicle by depressing the brake pedal. However, greater foot pressure on the brake pedal will be required to stop the vehicle and the stopping distance will be longer.
When the brake pedal is depressed slowly and firmly, you may hear a clicking noise and feel a slight pulsation. This is normal and indicates that the Brake Assist System is operating.
Using the brakes
Avoid resting your foot on the brake pedal while driving. This will cause overheating of the brakes, wearing out the brake pads and shoes faster and reduce gas mileage.
To help reduce brake wear and to prevent the brakes from overheating, reduce speed and downshift to a lower gear before going down a slope or long grade. Overheated brakes may reduce braking performance and could result in loss of vehicle control.
WARNING
• While driving on a slippery surface, be careful when braking, accelerating or downshifting. Abrupt braking or accelerating could cause the wheels to skid and result in an accident.
• If the engine is not running or is turned off while driving, the power assist for the brakes will not work.
Braking will be harder.
Wet brakes
When the vehicle is washed or driven through water, the brakes may get wet. As a result, your braking distance will be longer and the vehicle may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed while lightly tapping the brake pedal to heat-up the brakes. Do this until the brakes return to normal. Avoid driving the vehicle at high speeds until the brakes function correctly.
Parking brake break-in
Break in the parking brake shoes whenever the stopping effect of the parking brake is weakened or whenever the parking brake shoes and/or drums/rotors are replaced, in order to assure the best braking performance.
This procedure is described in the vehicle service manual and can be performed by a NISSAN dealer.
