How are rear brake pads changed?
Place wheel chocks in front of the front wheels to begin the process. (Avoid using the emergency brake; doing so makes it more difficult to take out the calipers.)
Place the jack in its proper position and elevate just enough to apply pressure to the jack. To remove the lug nuts from the wheel, use an impact or lug wrench. Spin the lug nuts off the lugs and raise the car until the wheel is raised off the ground. Then, remove the wheel.
Can you replace brake pads while using the handbrake?
Deactivate the electric parking brake before changing the rear brake pads. How come?
The braking system’s brake pads and rotors are used by the electronic parking brake system. The pistons in the caliper are under its control. You must first compress the caliper piston before you can remove the rear brake pads. If your parking brake is engaged, you won’t be able to perform this. To compress the pistons, you would be “fighting with the actuators.
While the actuators are pushing the pistons out, you run the risk of damaging them if you try to compress them. You might specifically harm the caliper piston mechanism and/or actuators.
Fortunately, there is a simple solution to stop this from happening. Before replacing the rear brake pads, you only need to disengage the electric parking brake. The actuators will turn off as a result.
You must switch on the parking brake servicing mode in order to deactivate the electric parking brake.
What’s the mechanism of an electronic parking brake?
When the typical handbrake lever is pressed up, a cable is tensioned. This cable applies pressure to the braking drums or discs in the rear of the vehicle, holding it securely in place. On the back axle of some vehicles, there may be a special disc and pads.
The basic idea is the same regardless of the technology a car employs: pressing the lever locks the back wheels to prevent the car from moving when you don’t want it to.
Electronic parking brakes, often known as electronic handbrakes, operate on the same principles but employ electric motors to produce the locking effect.
The rear brakes’ motors force the brake pads against the discs when the button is pushed or pulled. The motors frequently provide a comforting humming sound as they operate.
Most electronic handbrakes release themselves when you start moving. When you press the accelerator and raise the clutch past the point of biting in a manual transmission vehicle, the clutch will release.
The amount of throttle input’ an automobile needs to release the handbrake, however, is not standardized in the industry. Some need only a light touch of the accelerator to release, while others require quite a few revs.
Driving a manual car with an electronic handbrake can be challenging as a result. The tensing of the automobile at bite can seem rather noticeable, and the release can be quite harsh.
As you become used to it, don’t worry too much if you start to stall. It quickly becomes automatic.
