Kawasaki Concours 14 Brake Specifications (K-ACT ABS Explained!)

Kawasaki Concours 14’s front brake has dual 310 mm (12.2 in) front discs and four-piston calipers. The front brake disc has an outer diameter of 310 mm, an inner diameter of 80.5 mm, and a thickness of 5 mm.

The rear brake is a single 270mm petal-style disc accompanied by a single-piston caliper, also integrated with ABS technology.

The brake lever adjuster offers six positions, while the clutch lever adjuster has five positions.

The motorcycle employs a hydraulic brake system, which uses brake fluid to transfer force from the rider’s input to the braking components.

Front Brake Specifications

The Kawasaki Concours 14 ABS braking system has dual 310 mm (12.2 in) front discs and four-piston calipers. The front brake disc has an outer diameter of 310 mm, an inner diameter of 80.5 mm, and a thickness of 5 mm. 

The front brake system features a robust hydraulic disc brake setup.

The front brake fluid reservoir, marked with upper (B) and lower (C) level lines, must be maintained between these lines when the reservoir is held horizontally.

Rear Brake Specifications

The rear brake of the Concours 14 is a single 270mm petal-style disc accompanied by a single-piston caliper, also integrated with ABS technology.

Similar to the front, the rear brake system also utilizes a hydraulic disc brake.

The rear brake fluid reservoir, with upper (C) and lower (C) level lines, should be monitored for proper fluid levels.

Brake Pads and Brake Calipers

In 2018, the Concours 14 ABS model introduced floating discs equipped with 4-piston calipers boasting a substantial 310 mm (12.2 inches) size at the front.

Meanwhile, the 2020 iteration of the Concours 14 ABS features a single 270 mm petal-style disc coupled with a single-piston caliper, ensuring efficient braking with the added benefit of ABS.

One key aspect to consider when replacing brake pads for the Kawasaki Concours 14 is the HH friction rating, denoting the highest level of friction.

Notably, the brake pads also employ a double-segment vented design, a thoughtful feature aimed at dissipating heat and keeping the pads cooler during intense braking situations.

Brake Light Switches

The Kawasaki Concours 14 is equipped with brake light switches for both front and rear brakes.

The front brake light switch requires no adjustment, while the rear brake light switch should be adjusted according to the Periodic Maintenance Chart.

Regular inspections of the brake light switches are essential.

For the front brake, simply applying the brake should activate the brake light.

Similarly, the rear brake light switch should be checked for proper operation by depressing the brake pedal.

Any malfunction should be promptly addressed through adjustment by an authorized dealer.

Brake/Clutch Lever Adjuster

The brake lever adjuster offers six positions.

Riders can customize the released lever position by aligning the adjuster number with the corresponding marks on the levers.

Understanding the adjuster positions allows riders to set the distance from the grip to the released lever according to their preferences.

This feature enhances rider comfort and control during various riding conditions.

Brake Pedal Travel Adjustment

The brake pedal travel should be within the specified range (10 mm or 0.39 in.).

To adjust the rear brake light switch and consequently the pedal travel, riders can move the switch up or down by turning the adjusting nut.

K-ACT ABS

The Kawasaki Concours 14 ABS has the K-ACT ABS, an advanced anti-lock braking system designed for touring models weighing over 300 kg (661 lb).

This system is tailored to ensure optimal braking performance while preventing tire lock-up during deceleration.

The K-ACT ABS goes beyond traditional functionality by intelligently linking the front and rear brakes.

It continuously monitors the rider’s brake force on both ends and considers the vehicle speed, delivering highly effective braking without compromising chassis stability.

For instance, when the rider applies the front brake, the ABS ECU seamlessly engages the rear brake to maintain front-rear balance and prevent the bike from pitching forward.

Similarly, when the rear brake is engaged, the system activates the front brake to evenly distribute the load evenly, preventing the rear wheel from locking up.

The system’s sophistication extends to determining the optimal hydraulic pressure for each caliper based on the vehicle’s speed.

Maintenance and Adjustment

One remarkable feature of the Kawasaki Concours 14 is its automatic compensation for disc and disc pad wear in both front and rear brakes.

This means there are no specific parts that require manual adjustment, simplifying maintenance for riders.

However, it’s essential to be aware of the dangers of air in the brake lines.

If the brake lever or pedal feels mushy when applied, it may indicate air in the brake lines or a defective brake.

In such cases, immediate inspection by an authorized Kawasaki dealer is necessary to prevent accidents.

Fluid Level Inspection

Regular inspection of brake fluid levels is a fundamental aspect of motorcycle maintenance.

The fluid level in both the front and rear brake reservoirs must be between the upper and lower level lines when the reservoirs are held horizontally.

If the fluid level falls below the lower level line, riders should check for fluid leaks in the brake lines and promptly refill the reservoir to the upper level.

Tightening the cap and making a 1/6 turn is crucial during this process to ensure a secure seal.

Common Brake Issues

Rear brake dragging is the most common brake problem faced by Concours 14.

Rear brake dragging leads to overheating and, in severe cases, brake damage, lockup, or failure.

A common culprit is low brake fluid, manifesting as a spongy brake pedal or even non-responsive brakes. Add more fluid and inspect for leaks.

Another potential issue is the presence of air or moisture in the braking system.

Symptoms include a soft brake feel or a pedal that depresses the floorboard.

Inspect the master cylinder for any issues.
