Brake Pads?

[woodways3]

Hi i want to change the front discs and pads, Will pushing the caliper pistons back trigger a fault code ? If so will a simple code reader clear it ? Thanks .

If it helps, I've just repaired the rear brake calipers on my 2015 Hybrid Yaris, and in doing so I pushed back the pistons without any codes coming up.

I simply did not turn on the ignition until I had fully completed the work and had a firm brake pedal again.

Keep the keys well away from the car when your doing the brakes.

Ideally disconnect the 12v.

If you dont disconnect the 12v Battery, and open the driver door, doesnt the brake system repressurize and eject the pistons if they aren't assembled?

Also if you disconnect the Battery, is the boot lock manual or electronic? Some sites recommend putting a towel over the lock so the boot wont close shut.

If you have a smart key, then make sure you keep it well away from the car while doing the brakes - the car 'awakens' as you approach it with the key and pressurises the brakes. I looked at this a while back, and found some to-do's on Prius Chat - do your research! It could be an expensive trip to the dealer to reset the system.
