General
The rear brake pedal controls the rear wheel brake and is located on the motorcycle's right side. Operate the rear brake pedal with the right foot.
The front brake hand lever controls the front wheel brake and is located on the right handlebar. Operate the hand lever with the fingers of the right hand.

WARNING
Do not position fingers between hand control lever and handlebar grip. Improper hand positioning can impair control lever operation and cause loss of vehicle control, which could result in death or serious injury. (00032a)
Some models are equipped with an anti-lock braking system.
Non-ABS Brake System
Apply brakes uniformly and evenly to prevent wheels from locking. Use front and rear brakes equally for best results.

WARNING
Do not apply brake strongly enough to lock the wheel. A locked wheel will skid and can cause loss of vehicle control, which could result in death or serious injury. (00053a)
Anti-Lock Brake System (ABS)
Harley-Davidson's Anti-Lock Brake System assists the rider in maintaining control when braking in a straight-line emergency situation. ABS operates independently on front and rear brakes to keep the wheels rolling and prevent uncontrolled wheel lock-ups either on dry pavement or on slick surfaces such as gravel, leaves or when riding in wet conditions.
ABS: How It Works
The ABS monitors sensors at the front and rear wheels to determine wheel speed. If the system detects one or both wheels are slowing down too quickly, which indicates they are close to locking, or if the deceleration rate does not match a criteria stored in memory, the ABS reacts. The system rapidly opens and closes valves to modulate the brake caliper pressure utilizing only the brake lever/pedal pressure being applied by the rider. During ABS activation, the system provides the electronic equivalent of manually pumping the brakes and is capable of cycling up to seven times per second.
The rider will recognize ABS activation by the slight pulsing sensation in the hand lever or the rear brake pedal. The pulsing sensation may also be accompanied by a clicking sound from the ABS module. Both are the result of normal operation. Refer to
Table 1.
ABS: How To Use
While an advantage in emergency braking, ABS is not a substitute for safe riding. The safest way to stop a motorcycle is upright with both wheels straight.
Harley-Davidson ABS is a manual assist system. When in an emergency stopping situation, maintain pressure on the brakes through all ABS events. Do not modulate or "pump" the brake controls. The wheels won't lock until the end of the stop when motorcycle speed reaches approximately 6 km/h (4 mph) and ABS is no longer needed.

WARNING
ABS cannot prevent lockup of rear wheel due to engine braking. ABS will not aid in cornering or on loose/uneven surfaces. A locked wheel will skid and can cause loss of vehicle control, which could result in death or serious injury. (00362a)
ABS: Tires and Wheels
ABS motorcycles must always use tires and wheels that are the same as the original equipment. The ABS monitors the rotational speed of the wheels through individual wheel speed sensors. Changing to different diameter wheels or different sized tires can alter the rotational speed. This can upset the calibration of the ABS and have an adverse effect on its ability to detect and prevent uncontrolled wheel lockups. Tire inflation pressure that is significantly low also can have an adverse effect.
Table 1. ABS Symptoms and Conditions
SYMPTOM | CONDITION |
---|
Pulsing brake lever or pedal during an ABS event | Normal condition. |
Clicking sound during an ABS event | Normal condition. |
ABS lamp flashing | Normal condition - motorcycle turned on - speed under 5 km/h (3 mph). |
Perceived "surge" while braking | Normal condition - most noticeable when braking with one brake (front only
or rear only). Result of a reduction in deceleration which can be caused by
cracks or bumps in road, engine braking (high engine RPMs causing the rear
wheel to slow down), hard braking at slow speeds, and other conditions. This
is due to ABS modulating caliper brake pressure to prevent uncontrolled
wheel lock. |
Temporarily stiff rear brake pedal | Normal condition - engine braking (high engine RPMs causing the rear wheel
to slow down) or down shifting can activate ABS. If applying the rear brake
at the same time or immediately after, the ABS may be closing a valve to
prevent pressure to the rear brake. This is due to ABS modulating caliper
brake pressure to prevent uncontrolled wheel lock. |
Tire chirp | Normal condition - depending on surface, tire can chirp without locking
the wheel. |
Black mark on pavement | Normal condition - depending on surface, tire can leave a black mark
without locking the wheel. |
Wheel lock at low speed | Normal condition - ABS will not activate on front wheel below 5 km/h (3 mph) or on rear wheel below 8 km/h (5 mph). |
