Regen brakes disabled wrench light also came on and i feel shuttering on the brake during start motion and when applying brake but when select low gear at transmition the shuttering feeling stop

In general, EVs are equipped with the regenerative-hydraulic hybrid braking system. Whenever the regenerative braking torque is insufficient to offer the same deceleration rate as available in conventional vehicles, the hydraulic braking torque is applied.

You must have an electric or hybrid vehicle. They often use regeneration braking to convert otherwise lost energy during braking to electrical energy to help recharge the battery pack thereby extending range. There is obviously a fault in the system. You need to have the codes read (the codes are why the abs and regeneration lights are on) in order to diagnose the problem accurately.

Service Stability System Message The message center displays the service stability system message when any one of many VSES-disabling DTCs is set. The EBCM sends a serial data message to the IPC requesting this display.
It means there is a problem an till you get it fixed the stability control system is disabled ! ( EBCM ) electronic brake control module Has detected a problem an set a DTC - diagnostic trouble code in it's memory an had the message displayed !
Vehicle Stability Enhancement System (VSES)
The vehicle stability enhancement system (VSES) provides added stability during aggressive maneuvers. Yaw rate is the rate of rotation about the vehicle's vertical axis. The VSES is activated when the electronic brake control module (EBCM) determines that the desired yaw rate does not match the actual yaw rate as measured by the yaw rate sensor.
The desired yaw rate is calculated by the EBCM using, primarily, the following inputs.
?€¢
The position of the steering wheel

?€¢
The speed of the vehicle

?€¢
The lateral, or sideways acceleration of the vehicle

The difference between the desired yaw rate and the actual yaw rate is the yaw rate error, which is a measurement of oversteer or understeer. When a yaw rate error is detected, the EBCM attempts to correct the vehicle's yaw motion by applying brake pressure to one or more of the wheels. The amount of brake pressure which is applied varies, depending on the correction required. The engine torque may be reduced also, if it is necessary to slow the vehicle while maintaining stability.
VSES activations generally occur in turns during aggressive driving. When braking during VSES activation, the pedal may pulsate. The brake pedal pulsates at a higher frequency during VSES activation than during ABS activation.

The gearing system is designed to downshift as you are slowing down. These vehicles do not "free wheel" like the old ones did so you feel the drag when you slow down to a light. I even notice it when I go downhill, sometimes not even having to brake too much before coming to a stop on a slight grade. I imagine it does little for our fuel economy. If it were in a BMW or several other models I would blame regenerative braking but on a LR ,,,no.

Have you checked the rear brakes? They can cause shaking just like the front can.

{: ) A car swerving light on the instrument cluster is the StabiTrak indicator, sometimes called the traction control indicator. A wrench beside it tells it requires servicing.

Your vehicle is equipped with StabiliTrak, which combines antilock brake, traction and stability control systems and helps the driver maintain directional control of the vehicle in most driving conditions.
Traction control activates when the controller senses wheel spin. StabiliTrak will selectively apply the brakes and reduce engine torque to help regain traction.
Stability control activates when the controller senses a discrepancy between your intended path and the direction the vehicle is travelling. StabiliTrak selectively applies braking pressure at any one of the vehicle's brakes to help guide the vehicle in the direction which you are steering.
When you first start your vehicle and begin to drive away, the system performs several diagnostic checks to insure there are no problems. You may hear or feel the system working. This is normal and does not mean there is a problem with your vehicle. If driving conditions delay system initialization, the STABILITRAK NOT READY message may be displayed. If this is the case, your vehicle does not need servicing.
When the StabiliTrak system is both on and actively controlling the stability of the vehicle, the StabiliTrak light will blink for the duration of the event.
You may also feel or hear the system working. This is normal.
StabiliTrak will turn off automatically if a problem is detected in the system. The StabiliTrak light will come on and SERVICE STABILITRAK will be displayed on the DIC. For vehicles without a DIC, the StabiliTrak light and the StabiliTrak service light will both come on. If the SERVICE STABILITRAK message (or StabiliTrak service light) does not clear itself after restarting the vehicle, you should see your dealer for service.

it sounds to me like your brakes are at the wear limit and a metal tab that is built into the pad rubs the rotor to make the driver aware that he needs brake service(new pads). Other possibility is a wheel bearing going out: jack up car and turn wheel slowly to feel if the motion is smooth or rough and noisy, do not confuse with brake drag or noise

It should be bolted on. Depending on the model, things might look different, but a socket wrench set should be all that is required.
Maybe a pry bar.

Power Boosters Virtually all modern vehicles use a vacuum assisted power brake system to multiply the braking force and reduce pedal effort. Since vacuum is always available when the engine is operating, the system is simple and efficient. A vacuum diaphragm is located on the front of the master cylinder and assists the driver in applying the brakes, reducing both the effort and travel he must put into moving the brake pedal.
The vacuum diaphragm housing is normally connected to the intake manifold by a vacuum hose. A check valve is placed at the point where the hose enters the diaphragm housing, so that during periods of low manifold vacuum brakes assist will not be lost.
Depressing the brake pedal closes off the vacuum source and allows atmospheric pressure to enter on one side of the diaphragm. This causes the master cylinder pistons to move and apply the brakes. When the brake pedal is released, vacuum is applied to both sides of the diaphragm and springs return the diaphragm and master cylinder pistons to the released position.
If the vacuum supply fails, the brake pedal rod will contact the end of the master cylinder actuator rod and the system will apply the brakes without any power assistance. The driver will notice that much higher pedal effort is needed to stop the car and that the pedal feels harder than usual.

This is a common fault often caused by low battery voltage, before you start taking expensive actions with the park brake modules etc get your battery checked for 100% efficiency.
Hope this helps, good luck.

Try this, Since you are applying the hand brake. Manually pull up on the emergency pedal and see if the light goes out. If this does work then you could have one of several problems. but, I am thinking that you might be able to adjust the brake tensioner if this car has one.
