DAPURPACUID – It cannot be denied, the active safety features installed in the latest vehicles can be said to be ‘safety gods’ when you drive.
The Anti-lock Brake System or ABS feature is a braking system on vehicles to increase driving safety and security. Not only in four-wheeled vehicles, this feature has been included in many motorbikes.
The ABS system installed in two-wheeled vehicles functions so that when braking suddenly, the motorbike does not experience a skid or stall, especially when the road conditions are wet or slippery.
This system is equipped with sensors. When the motorbike is running, the speed sensor will read the speed of both the front and rear wheels. When there is a difference in speed, this information will be sent to the ECU (Engine Control Unit).
Then the data from the ECU is forwarded to the modulator. The ECU will activate the solenoid. When the brake lever is pulled, the fluid pressure on the caliper will automatically become very strong.
The process of reducing, holding and increasing fluid pressure takes place very quickly, around 15-50 times per second, so that the wheels will not lock when sudden braking occurs.
Then what components are in the ABS braking system on a motorbike. As is known, many Honda motorbike lines have been equipped with this feature.
1. Master Cylinder
This component functions as a converter of mechanical movement from the brake pedal into hydraulic pressure. When the master cylinder works, the piston will push brake fluid. This pressurized brake fluid will be distributed to the ABS pump.
2. ABS Hydraulic Control Valve
There are at least three valves in the ABS system. This component is the gate for brake fluid from the master cylinder to the wheel cylinder. This valve regulates hydraulic pressure from the master cylinder to the wheel cylinders. Here’s how it works:
– Valve one is fully open to maximize brake fluid pressure directly to the brakes;
– Valve two prevents brake fluid pressure from being transmitted to the brakes; And
– Triple valve blocks some of the brake fluid pressure so that only some of it is transmitted to the vehicle’s brakes.
3. ABS pump
The pump in the ABS braking system functions to restore hydraulic pressure to the wheel cylinders after the hydraulic pressure is reduced due to opening the ABS valve.
When a wheel is locked, the hydraulic pressure on the wheel is reduced until the wheel spins again. Once the wheels turn, the ABS pump quickly restores hydraulic pressure.
4. ABS Control Module
The ABS Control Module is a processing device that regulates when and for how long the valve opens and closes. This module also regulates when the ABS pump should work.
The module in the ABS control system works based on data sent from sensors. This data is then processed to give commands to the ABS valve and pump.
5. Speed Sensor
These sensors are installed on the front and rear wheels to read the wheel rotation speed and send this data to the ABS module.
6. Wheel Cylinder
Functions to change the hydraulic pressure in the brake fluid into a mechanical movement that pushes the brake lining to clamp the disc.
7. Brake Hydraulic Lines
This part functions as a path for the brake fluid to flow from the master cylinder to the wheel cylinders. ABS is not to make the brakes more grippy, but is an electronic braking system so that the wheels don’t lock.
8. ABS indicator
Motorcycles equipped with ABS have an indicator light on the speedometer that shows its condition. If the indicator shows any of the following signs, there may be a problem with the ABS system.
– The indicator lights up or flashes while driving;
– The indicator does not light up when the ignition key is turned to the On position; And
– The indicator does not turn off at speeds above 10 km/h.
If the ABS indicator on the meter panel remains on when the motorbike is running, the front and rear brakes will function as usual, but without the anti-lock feature functioning.
The ABS indicator may also flash if the rear wheel is turned with the motorcycle off the ground. In this condition, turn the ignition key to the Off position, then back to the On position.
In general, the ABS indicator will automatically turn off after the motorbike speed reaches 30 km/hour. If there are indications that the ABS system is starting to have problems, including the braking system, immediately check the condition of the motorbike at a repair shop.
Don’t hesitate to entrust routine checks and maintenance to reliable and experienced technicians at the nearest AHASS workshop, so that your motorbike is always kept in top condition.
One of the Honda motorbike models equipped with ABS is the Vario 160. Supporting the braking system are 220 mm hydraulic disc brakes at the front and rear.
This combination provides more stable braking control. Including to match the performance of the 160cc eSP+ engine. (dpid/TH)
